of 148 1.1 How to Use This Manual This manual is divided into three main sections: 1. Installation and wiring (Section 2) 2. Technician level configuration (Section 3) – this section is meant to be consulted when going through section 2. 3. GSC400 Operation. Day to day end user operation and configuration (Section 4) In addition there are appendixes that contain detailed supplementary information. 1.2 Safety / Information Generator systems contain high voltage circuitry.
of 148 1.3 Receiving, Handling, and Storage Receiving: Every effort is made to ensure that your GSC400 gen-set controller arrives at its destination undamaged and ready for installation. The packaging is designed to protect the GSC400 internal components as well as the enclosure. Care should be taken to protect the equipment from impact at all times. Do not remove the protective packaging until the equipment is at the installation site and ready to be installed.
of 148 1.4 GSC400 Product Number Identification The GSC400 series product numbering scheme (i.e. product number) provides various information – including options selected by the customer – about the unit. A product number has the format given in Figure 1. The product number is located on the backside of the GSC400 controller under the bar code.
of 148 2. Installation and Wiring This section contains information on the wiring of the GSC400 controller. It is meant to be used in conjunction with Section 3 GSC400 Configuration which covers the configuration of the GSC400. 2.1 MOUNTING ..................................................................................................................................13 2.2 GSC400 COMPONENT RATINGS / STANDARDS ........................................................................15 2.
of 148 install the GSC400 in a grounded enclosure. Ensure that the ground wire makes direct contact with the metal in the enclosure; scrape off any paint. Also consider using shielded spark plugs. Isolate the GSC400 enclosure with isolation mounts to prevent excess vibration to the GSC400. It is recommended to limit the maximum average ambient temperature around the GSC400 to 700C to provide headroom. Figure 3 - Dimensions of mounting holes.
of 148 2.2 GSC400 Component Ratings / Standards UL Listing The GSC400 is UL listed to UL508. For conditions of acceptability refer to UL file number: E250327 or contact DynaGen. The conditions of acceptability are also packaged with every unit. U 12V / 24V Operation The GSC400 controller can be placed in either 12V or 24V electrical systems. The user must order the correct GSC400 as 12V operation requires 12V relays and 24V operation requires 24V relays.
2.3 Wiring - Overview This section will explain how to wire your application to the GSC400. Table 1 gives the type and part number for all the mating plugs that plug into the GSC400 terminals. If you do not wish to crimp your own plugs, Table 29 on page 120 gives the part numbers of the various starter-kit harnesses you can order from DynaGen. Only commonly used circuits on each connector are wired. Table 29 lists the circuits (i.e. wires) that are included as part of the harness.

of 148 2.4 Powering the GSC400 and Basic Connections 1 2 3 Engine Logic Battery Logic Extra Relay Logic Menu Location Advanced Setup > Engine Logic Advanced Setup > Battery Setup Advanced Setup > Outputs Setup > Extra Relay Page 47 57 69 There are a group of 8 spade terminals on the back of the GSC400. Their functions are described below.
of 148 Emergency Stop Input Pin 9 of the configurable switched input connector must be grounded (can use pins 11 or 12) to disable the emergency stop feature. When enabled the emergency stop feature forces the controller to remain in the OFF mode and sounds the buzzer. Remote Start Contacts (RSC) A normally open switch needs to be placed across pin 10 of the configurable switch input connector and ground (pin 11 or 12 on the same connector can be used for convenience).
of 148 2.5 Speed Inputs 1 Speed Sensing Menu Location Advanced Setup > Speed Sensing Page 55 The GSC400 senses engine speed via two spade terminals on the bottom of the unit (not needed for J1939). Magnetic input, generator AC voltage, or J1939 can be used. 2.5.1 Generator AC Voltage / Magnetic Pickup Two wires must be run to the speed inputs (even if using generator output).
of 148 This could be caused by the GSC400 speed sensing terminals picking up stray signals during cranking. The speed sensing on the GSC400 is sensitive in order to pick up low voltages during cranking. The GSC400 then thinks the generator has started. Confirm by checking the speed displayed on the controller during cranking (value beside “RPM”). 1. Check that there are no breakers off. This can unload the GSC400 sensing inputs allowing the wiring to act as an antenna. 2.
of 148 2.
of 148 2.6.2 Senders The sensor types Dynagen supports out of the box for engine temperature and oil pressure are given in the following table. Fuel Level, Oil Level, and Fuel in basin types are not supported out of the box; the PC Configurator must be used to store a custom table for these types. Table 4 – Default Senders for Temperature and Oil Pressure Sender Manufacturer and Type Supported Sensing Range Part Number Pins on J2 Datcon High Range 3 and 4 129 to 330 0F High Temp.
of 148 Each sender has a particular pin it is supported on. If your sender part number is not listed in the table or your desired pin is not supported, the PC Configurator can be used to create and store a custom table (refer to manual MAN-0079, the GSC400 PC Interface manual). The GSC400 has Open and Shorted sender diagnostic features. These are disabled by default. The Open Sender Detection will trigger if the analog input voltage rises above 4.76V.
of 148 1. Confirm that the sender is connected to the correct input pin terminal. Check the wiring for continuity. Check that the GSC400 is setup correctly in the advanced menu. 2. With the generator not running, unplug the sensor (analog inputs) plug from the controller. It’s the 2x4 pin connector on the bottom. On the GSC400 sensor terminal, measure the DC voltage of the input pin to battery negative. Do this on the GSC400 terminal, not the plug. It should read 5VDC.
of 148 2.7 AC Voltage / AC Frequency 1 2 AC Voltage AC Frequency Menu Location Advanced Setup > AC Voltage Advanced Setup > AC Frequency Page 58 58 The GSC400 controller requires a neutral reference from the generator. All voltages are measured line to neutral and then converted for display as line to line if required. Battery negative needs to be connected to the neutral of the electrical system as the GSC400 AC voltage sensing requires a battery negative reference.
Figure 5 – GSC400 Three Phase Voltage Configurations
Figure 6 – Three Phase AC Voltage Step down Options
2.8 AC Current 1 AC Current Menu Location Advanced Setup > AC Current Page 62 The GSC400 controller is designed to measure AC current from the generator with the use of current transformers (CTs). CTs with a rating of 5A on the secondary are required. The maximum allowed current on the GSC400 AC current terminals is 5A. U Use large AWG wires for runs longer than 5ft. The shunt resistors used for sensing of current are very low resistance. The accuracy can be affected by resistance of CT wires.
Figure 7 – CT Installation Do’s and Don’ts (from DWG1469R1.0) 2.9 AC Current and Voltage Calibration Each GSC400 undergoes an advanced two point calibration at the factory and typically does not required calibration except in the following instances: 1. Current Transformers (CT) are used that have poor tolerances. 2. The AC signal from the generator is distorted with a high total harmonic distortion (THD). One cause is VFD (Variable Frequency Drive) devices.
2.10 Configurable Switched Inputs / Configurable Outputs 1 2 Configurable Switched Inputs Configurable Outputs Menu Location Advanced Setup > Inputs Setup Advanced Setup > Outputs Setup Page 67 69 Configurable Switched Inputs Four of the switched inputs (A to D) trigger when battery + is applied. The other four inputs (E to H) trigger when battery - is applied. The switch inputs are user programmable. They are disabled by default.
Figure 8 – Configurable Switched Input / Configurable Output Example
of 148 2.10.1 Timed Output on Failure Shutdown If you wish to provide a timed output when the engine shuts down you can do the following. 1. Set the “Energized to Stop” feature to one of the Switched Inputs A to H. 2. Set the “Energized to Stop” duration in the Engine Logic menu to the duration you wish to time the configurable output. 3. Set the desired Configurable Output you wish to have timed. Only failures are valid. Wire the GSC400 as shown below.

of 148 Troubleshooting Notes 1. To check for proper CAN communications place GSC400 in AUTO mode with the ECU powered and check that the engine temperature on the front panel display is not displaying N/A (engine temperature must be set to J1939). “N/A” indicates no communications with the ECM. 2. The ECM should start and run the engine – even if there are no CAN communications with the GSC400 – when the GSC400 turns on the fuel and crank outputs.
of 148 2.12 Modbus Setup 1 Modbus (RS485) Menu Location Advanced Setup > Set Modbus Page 74 Modbus has the capability to start and stop the genset and to transition from OFF to AUTO to do this. Modbus should be disabled while performing maintenance or repairs by unplugging the Modbus connector. GSC400 has a RS485 connection and supports the Modbus protocol. It is a slave device and must be polled by a master.
of 148 Communication Notes: 1. The GSC400 only supports commands 0x03 (read multiple registers) and 0x06 (write single register). If an attempt is made to send another command the GSC400 returns “incorrect command”. 2. Can only request to read 20 registers at a time. If over 20 GSC400 returns “illegal data address”. 3. Also need to watch out for discontinuities in register map. The GSC400 will return invalid data for non-existing registers (often returns a value of 0). 4.
of 148 2.13 Idle Mode 1 2 Configurable Switched Inputs Configurable Outputs Menu Location Advanced Setup > Inputs Setup Advanced Setup > Outputs Setup Page 67 69 For generators that have the capability of idling at a lower speed than the speed at which power is produced, the GSC400 controller has an Idle Mode feature that suppresses the warnings and failures for under-voltage, under-frequency, and under-speed. The GSC400 displays “Idle Running” when this feature is enabled.

of 148 3. GSC400 Configuration This section will explain the various menus used to configure the GSC400. Most GSC400 configuration is done from the Advanced Setup Menu. 3.1 MAKING MENU SELECTIONS ......................................................................................................44 3.2 ADVANCED SETUP MENU OVERVIEW ........................................................................................45 3.3 ENGINE LOGIC ..................................................................
of 148 Important! For Firmware Versions Below 2.00 After changing any settings on the controller, the controller needs to be reset. This can be done one of two ways: 1. Power off, wait for 2s, and power on the controller. 2. Press the Run key, wait until the controller begins the start sequence and then press the OFF key. You will see a flickering of the screen as the controller updates. The GSC400 incorporates an Advanced Setup menu. Only OEMs or knowledgeable users should change these parameters.
of 148 If you are satisfied with the selection then you must highlight the selection and then press enter. You will then be taken back to the previous menu. If there is no checkmark you must make a selection. See the next bullet point. If you wish to make another selection scroll down to the desired selection and press enter. A checkmark should appear beside the option selected. Then – with the desired option still selected – press enter again to exit the menu. 3.
of 148 Exerciser Set Inputs Setup (i.e. Configurable Switched Inputs) Battery Setup Set Password Set Maintain Set Modbus Common Faults Other Settings occurs. Generators require periodic operation as part of their scheduled maintenance. This menu allows settings to control how often the engine/generator is started and for how long. This menu allows you to assign features/warnings, for example low oil pressure, to one of eight digital inputs.
of 148 3.3 Engine Logic The Engine Logic menu contains settings that control the starting and stopping of the engine. All parameters in bold below are located in the engine logic menu unless otherwise noted. The Crank Disconnect setting determines the speed that must be attained before the crank output is turned off and the genset is considered to be running. The Crank Oil Pressure parameter is used to determine when to check for the Locked Rotor condition.
of 148 If the Midheat Time is greater than zero, the glow plug output remains on during cranking but not during crank rest. The glow plug output turns off if a crank failure occurs, once crank success is reached (unless the PostHeat is set to a value greater than 0s), or if the Midheat time expires. After the crank rest delay expires, the controller turns on the fuel and crank outputs and attempts to start the generator again. This is repeated until the number of tries equals the Crank Attempts.
of 148 go into Cool Down mode where an output is turned on (one of the configurable outputs must be set to Cool Down). Once the Cool Down time has expired, the fuel relay is turned off and the controller enters the OFF mode. By default it is possible to manually bypass cool down by pressing the OFF or AUTO keys. To prevent this, the Bypass Cooldwn can be set to disabled. If a failure occurs, cool down is bypassed and the GSC400 goes into the FAILURE mode.
of 148 3.4 Sensor Inputs The GSC400 has support for the following sensor types: Table 7 – GSC400 Engine Parameters Engine Parameter Advanced Menu Location High Engine Temperature High Engine Tmp Oil Pressure Oil Pressure Fuel Level Fuel Level Oil Level Oil Level Fuel In Basin Fuel In Basin Low Engine Temperature Low Engine Tmp Auxiliary Analog 1 Aux Analog 1 Auxiliary Analog 2 Aux Analog 2 Negative engine temperatures are not allowed for the sender inputs on the GSC400.
of 148 triggered. The controller will display a message and sound the alarm in the case of a warning or will shut down and sound the alarm in the case of a failure. 3.4.1 Switched Inputs If using a switch, it must be switched to ground but can be either normally open or normally closed. Set the “ Signal Source ” menu to “Switch Input” and the “ Switch Setting ” menu to “Closed = Fail” for normally open switches or “Open = Fail” for normally closed switches.

of 148 Open Sender Detection or Shorted Sender Detection provides diagnostics on the sender. See the installation chapter for more details. Set to Warning, Failure, or Disable. When changing the units, the controller will do a conversion of all settings to the new unit. It is possible that the conversion will cause one or more settings to go out of bounds. 3.4.4 Low and High Engine Temperature The Low and High Engine Temperature types can share the same sender.
of 148 They can be programmed with low and high warning and failure levels. The warnings and failures are displayed as “Short Aux An1”, “Open Aux An1”, “Low Aux An1”, and “High Aux An1”. The “Aux An1” is the programmable portion mentioned above. They can be programmed to measure and display three measurement types: Temperature, Pressure, and Level. These special submenus are located under the standard submenu items in the Aux Analog 1 / 2 menus.
of 148 3.5 Speed Sensing The speed sensing menu allows you to select the source to use for sensing the rotational speed of the engine. There are three options to choose from: 1. J1939 Input – If the engine/generator comes equipped with an engine control module (ECM) that supports the J1939 protocol then the GSC400 can obtain the engine speed from the ECM. 2.
of 148 For example if you have 100 teeth on the flywheel that the magnetic pickup sensor is attached to and the speed that your generator runs to produce power is 1800RPM the calculation would be: Rated Frequency (Hz) = (100 x 1800) / 60 = 3000Hz. You would enter 3000Hz for the Rated Frequency. Refer to the following tables for more examples.
of 148 3.6 Battery Setup The Battery menu allows the user to set the low and high battery warning and failure levels. In addition, the generator can be made to automatically start when in the AUTO mode if the voltage drops below the Recharge Level. The controller will display Low Voltage During Cranking on the screen if during cranking the voltage drops below the Low Vol InCrank setting. Note: When the generator is running, the battery voltage will equal the alternator charging voltage.
of 148 3.7 Generator (AC Voltage / Current / Frequency) Setup The AC Frequency, AC Voltage, and AC Current menus allow the measurement and display of the AC voltage, current, and frequency from the generator. 3.7.1 AC Frequency In the AC Frequency menu, under and over frequency warnings and failures can be configured. The DisconnectFreq setting is used by the GSC400 controller as a backup to the speed input (only if speed is set to magnetic pickup).
of 148 Selecting a Voltage Group to Use The Voltage Group submenu can be used for this purpose. Alternatively one or two configurable switched inputs can be used to determine the voltage group to be used. See section 3.7.2.1 below. The configurable switched inputs override the Voltage Group submenu. Table 12 – GenSet Configurations and How to Configure Them in the GSC400 Refer to Figure 5 on page 29 for a diagram of each of the various three phase configurations.

of 148 3.7.2.1 Voltage Select Inputs You can choose a voltage configuration by setting one or two of the configurable switched inputs to Volt Select 1 and Volt Select 2. This allows the GSC400 to automatically re-configure its voltage display as well as warning/shutdown trip points relating to AC voltages and currents. This is useful for mobile generators where the voltage selections can be selected via a CAM switch. Warning: The Voltage Select Inputs override the Voltage Group parameter.
of 148 3.7.3 AC Current The GSC400 controller is designed to measure AC current from the generator with the use of current transformers (CTs). The maximum current on the AC current terminals of the GSC400 is limited to 5A. The “Turns Ratio” sub menu is used to setup the CT ratio. All numbers in this menu are in terms of 5A. For example selecting 1000 is the same as 1000:5A (the GSC400 displays 1000A on the screen when the current measured on the GSC400 AC Current terminals is 5A).
of 148 3.8 J1939 Setup The GSC400 will work with any generator as long as it supports the standard messages listed in the SAE J1939 specification. Standard messages include oil pressure, engine temperature, and engine speed. Some engine control modules have proprietary messages that are intended for specialized devices and are not displayed by the GSC400. Viewing Engine Parameters from J1939 To use J1939 instead of a local switch or sender: 1.

of 148 until the GSC400 accesses the data from the bus. Note that loss of ECM may not be triggered since other parameters may be receiving data from the bus. ECM Boot-up Delay ECMs can take up to 10s to boot-up when they are first powered. Ensure that the crank time is long enough to take this into account. If extended cranking is not desired the glow plug (preheat) time can be set to turn on the fuel relay for a set time before cranking begins. Ensure that no configurable output is set to preheat.
of 148 The user can enable/disable the DTC feature and configure its behavior with the following settings. DTC DISPLAY – This setting enables or disables active fault messages (DM1) monitoring. When the DTC DISPLAY feature is enabled the GSC400 can receive active faults in the RUNNING, OFF and AUTO modes on the J1939 bus. Any new received active faults will trigger a message "NEW ACTIVE DTC" and the user can read the message on the GSC400 front panel display.
of 148 3.9 Digital Inputs (Configurable Switched Inputs) Setup There are eight configurable switched inputs. Each input can be selected to any of the features given in Table 18 below. Table 17 – Configurable Switched Input Selections Name Low Air Pressure Low Hydraulic Pressure Low Oil Pressure EPS Supplying Load Description This input generates a Low Air Pressure failure when active only in Crank. It is ignored in the OFF, AUTO, and RUN modes.
of 148 Running” is displayed on the GSC400 display when this input is active. The idle mode can also turn on a configurable output (see the Voltage Regulator configurable output feature in Table 18 on page 69). This output is usually used to turn off the generator voltage regulator when idle mode is entered but can be used for any purpose.
of 148 3.10 Digital Outputs (Configurable Outputs) Setup There are eight 200mA configurable outputs (all switched to ground) and one 40A digital output (dry contact), the Extra Relay output, all of which are configurable. Each feature (listed in Table 18 below) is permitted to be set to only one configurable output.

See section 3.5 for more details.
of 148 Warning Backlight Auxiliary Warning Temperature Warning (section 3.4) is activated. This turns off the digital output if the LCD backlighting turns off. The controller enters the sleep mode (section 4.4.2) when this occurs. This turns on the output if the Auxiliary Warning Digital Input (see Table 17 in section 3.9) is active. Maintenance Timer This turns on the output if maintenance is required to be performed on the engine/generator. See section 3.13.
of 148 3.11 Exerciser Setup The GSC400 can be set to automatically start the genset at regular intervals while in the AUTO mode. This is controlled by the Exerciser Setup menu. The Exerciser Enable should be set to Enabled if this feature is desired. The GSC400 will display a message and sound the buzzer for a set amount of time (Pre-Alarm Delay) to alert nearby personnel that the generator is about to start. The engine/generator will run for a set period of time (Run Duration) and then shut down.
of 148 3.12 Password Setup The GSC400 allows a 4 digit password to be entered to protect the advanced setup menu from any unauthorized changes. This password will be needed to perform any changes to the advanced setup. If the password is entered incorrectly, the controller will allow 3 more tries before the GSC400 returns back to the main menu. To set each digit of the password, do the following: Select Password No.1 (Digit 1) Enter the desired number 0-9 Select Password No.
of 148 3.13 Set Maintain This menu controls the service feature that is used to alert the user of required generator maintenance and can be enabled or disabled from this menu. If enabled, the count interval menu allows the user to set the number of hours until next service. The number of hours to next service is displayed in the Basic Setup menu under Maintenance (see Table 6 on page 90).
of 148 Figure 11 – Example of Common Fault 1 Usage 3.16 Other Setting The Other Setting menu contains the settings used to control the features in the following sections. 3.16.1 Dummy Load The dummy load feature allows the user to turn on an output if the AC current is below a settable threshold (Load On Point). This is useful for applications where the generator must have a minimal load to prevent damage to the generator.
of 148 3.16.2 LCD Heater There is an option for an LCD heater that allows the LCD display to operate normally down to -400C (for more information contact Dynagen). There is an option in the “Other Setting” menu called “LCD Heater” that allows the heater to be enabled or disabled. It is set to disabled by default. 3.16.3 Fan Control The fan control is meant to operate in conjunction with the engine run configurable output. The fan control also has a “fan control” configurable output that must be set.

of 148 4.4.3 AUTO Mode When the GSC400 is set to the AUTO mode, automatic starting will be enabled. Possible triggers include RSC (start/stop), battery recharge and exerciser run (all of which are controllable from the menu system). If the engine is started, failures will be automatically detected allowing for safe engine operation. While in AUTO mode the controller will display engine temperature, battery voltage, fuel level, and engine hours. The LCD will turn off after a programmable amount of time.
of 148 the switched input connector. The controller will automatically shut the GenSet down and re-enter the AUTO mode if it initiated a generator start. When the controller is in the RUN mode, generator parameters will be displayed on the screen to allow the user to monitor the engine status. These include engine speed, generator voltage and current, and engine temperature as well as others. The parameters are displayed in groups and the screen scrolls between the various groups.
of 148 4.5 GSC400 Start / Stop Behavior THE LCD WILL TURN OFF DURING THE FIRST 2 SECONDS OF CRANKING TO LIMIT THE VOLTAGE DIP EFFECT ON THE CONTROLLER DURING CRANKING. Since the GSC400 startup and shutdown behavior can be configured by the manufacturer the exact startup and shutdown behavior can vary. Behaviors such as the amount of time to wait before starting, preheat, crank time, etc, all are programmable. There are three ways to start the generator (start conditions): 1.

of 148 4.8.1 Clock Setup The Clock Setup menu will allow you to set the clock. The clock is important if you are planning to use the event log (records all failures and warnings and when they occurred) or the exerciser feature (starts the generator for a settable period).
of 148 The controller can be made to NOT sound the alarm when the controller is not in the AUTO mode. This is controlled by the Not In Auto setting. “Disable Beep” is the default selection. The OFF Mode Start setting can be set to Enable to allow a manual start from the OFF mode. Otherwise a manual run can only be performed when the controller is in the AUTO mode.
of 148 4.8.3 Event History Log The GSC400 incorporates an event history logging system. When engine failures, events, or DTCs (Diagnostic Trouble Codes) occur, an entry is created in the GSC400 Event History Log. See Table 24 – – Event Log Entries below for the possible events that are stored. A total of 100 entries can be recorded. Entries may be viewed simply by scrolling up or down using the “UP” and “DOWN” keys.

Flashing Red A flashing red illuminated LED means the GSC400 is in OFF – sleep mode. Solid Red A solid red illuminated LED represents a Low Coolant (Temperature and/or Level) failure condition.
of 148 4.10 Warnings and Failures The GSC400 incorporates many types of warnings and failures. Most are only active in the RUN mode while a few are also active in the AUTO and/or OFF modes. Warnings and failures can be triggered from a Switched Input, Analog Input, AC Voltage, AC Current, Speed Signal Input, as well as others. The Advanced Setup section of this manual will give more information of the specific warning and failures for each type of input.
of 148 4.10.1 Returning to OFF Mode from a Failure When the GSC400 enters in the FAILURE mode press the Off key. This will silence the alarm and “ENTER TO RESET?” will appear on the GSC400 display. Press the Enter key to exit the FAILURE mode and enter the OFF mode. Note: it is not possible to enter the AUTO mode directly from the FAILURE mode. 4.10.2 Diagnostic Trouble Code Shutdowns This section only applies for electronic engines and if the Diagnostic Trouble Code (DTC) feature is enabled.
of 148 For mechanically-connected engines, once the maximum is reached it will continue to display the maximum unless the hourmeter is reset through an authorized dealer. J1939 has the priority; it overrides the local engine hour value when the GSC400 is connected to J1939. 4.11 J1939 This section applies if J1939 is enabled for one or more parameters. The parameters are displayed the same for J1939 as they are for analog inputs.
of 148 4.12 J1939 Diagnostic Trouble Code (DTC) Display This section applies for electronic generators (i.e. generators that use J1939) which have the DTC feature enabled. The GSC400 can read J1939 diagnostic trouble codes (DTCs) from an electronic ECM, if enabled (see section 4.1.3 on page 65 for information on how to configure and customize the GSC400 DTC feature). 4.12.1 DM1 Messages When the engine’s ECM detects a fault, it will send an Active Diagnostic Trouble Code, DM1, message.

of 148 Appendix E Modbus Map The GSC400 follows the Modbus standard. Modbus is a master-slave communication protocol in which only the master can initiate a communication request. A slave device never initiates communications. Please refer to the standard for more details. E.1 Communication Details The GSC400 communicates on Modbus only as a slave device. The GSC400 supports only the modbus RTU (Remote Terminal Unit) mode. Query and response messages share the same message structure.
of 148 modbus register 40002. Use “0x01, 0x2C” for modbus register 40300. 2. The third and forth bytes specifies the number of registers to read. Larger requests will generator a modbus error. For example use ‘0x00, 0x14” to read 20 registers. 0x06 – Write Single Register Note: There are only two addresses that support the 0x06 command: 40098 and 40130. The Data field contains 4 bytes: 1. The first two bytes specifies the starting register to write to (value = modbus register - 40000). 2.
of 148 When the GSC400 controller goes from the Run to OFF or Menu to OFF, modbus communications will be unavailable until the controller is in the OFF mode for 2 seconds.
