Interfacing the XMP 2600 1 The GPIB interface Interfacing the XMP 2600 The XMP 2600 has two types of interfaces used for remotely controlling it: a GPIB (IEEE 488) Interface and a Serial (RS232) Interface. The two interfaces differ only in the communication hardware and protocol. Input and Output Queues, Command and Query Parsing and Execution are identical no matter which interface is being used to remotely control the XMP 2600. The XMP 2600 has two remote controlling modes.
Interfacing the XMP 2600 The serial interface The serial interface The Serial Interface is RS232 hardware interface with three types of operating modes: Monitor Mode, Remote Terminal Control Mode and Remote Computer Control Mode. Pressing the terminal’s ENTER key while the Serial Interface is in Monitor Mode and the GPIB Interface is OFF will cause the Serial Interface to switch to the Remote Terminal Control Mode.

Usage Guidelines 2 How to communicate with the XMP 2600 Usage Guidelines How to communicate with the XMP 2600 The purpose of this section is to give the user of the XMP 2600 power system basic guidelines on how to communicate with the Power Supply.
How to communicate with the XMP 2600 Usage Guidelines To use this synchronization feature properly, you must follow each message sent to the XMP 2600 with a read operation, reading one character and verifying its value (6). Recovering from communication halts If, for some reason, communication with the XMP 2600 halts, use one of the following methods to clear the XMP’s input and output queues and reestablish communication: 1. Press the front panel LOCAL button. 2.
Usage Guidelines Recommendations on using the XMP 2600 Starting a session Issue a CLR or RESET command (and wait for 15 seconds) when you start using the XMP 2600. This will ensure that the XMP 2600 is in a known state, ready for you to program it. When queries are not used If you do not use queries often (see bellow) in your program, send commands in small groups (no more than 4 per second). Use delays to spread commands over time, if necessary.
Recommendations on using the XMP 2600 Usage Guidelines Identify the XMP 2600 Using the *IDN? query, it is possible to verify that the device you are communicating with is indeed a XMP 2600 power system. The *IDN? query also returns the firmware revision code for the XMP’s main controller. Use the GPIB? query to make sure the XMP 2600 is operating in IEEE488.2 mode.
Usage Guidelines Recommendations on using the XMP 2600 Check occupied channels Power Modules of the XMP 2600 have addresses that assign them to “channels” (or “slots”). Use the CHNL? query to find out which channels are occupied by Power Modules. Check installed Power Modules Once you know what channels are occupied, your next step is to verify that those channels are assigned the correct Power Modules.
Recommendations on using the XMP 2600 Usage Guidelines Protection setup Use the PROT command to setup the way Over Voltage and Over Current protection values are assigned (automatically or manually). If you have decided to use manual protection settings, use the OVSET and OCSET commands to setup the desired protection values. Select the Foldback scheme you wish to use (FOLD command) and the amount of reprogramming delay you wish to apply (DLY command).
Usage Guidelines Handling SRQ and the IEEE488.2 Status Structures To globally control the outputs of all the Power Modules, use the OUT command with no module number. Verification Read the output voltage and/or current of the activated Power Modules. Use the VOUT? (measured at the output connector), VLOAD? (measured at the sense lines) and IOUT? queries to verify proper operation. Allow at least a second from the output activation to the time you read back the output’s actual values.
Handling SRQ and the IEEE488.2 Status Structures Usage Guidelines The status reporting mechanisms of the XMP 2600 are rather complex. If you do not intend to use the advanced warnings and protection features of the XMP 2600 you may choose to disregard most of the reported status with the exception of the main status byte and the error code registers. Definitions of We will start this discussion with a short explanation of the various elements comprising structural the Status Structures.
Usage Guidelines Responding to SRQ events Handling SRQ and the IEEE488.2 Status Structures The SRQ event of the IEEE488.2 bus is the summary of the entire Status Structure of the XMP 2600. The following paragraphs will show how to traverse the Status Structure tree in order to find the cause of the generated SRQ. This explanation will, also, show how to setup the programmable elements of Status Structure in order to be notified only on events of interest.
Handling SRQ and the IEEE488.2 Status Structures Usage Guidelines Remote communication time out The Remote Communications Time Out bit is the only element of this part of the Status Structure. The bit is set to 1 when the Time Out mechanism is enabled and a Time Out event occurs.
Usage Guidelines Handling SRQ and the IEEE488.2 Status Structures The first element of the Power Module Status Structure we should look at is the Events Register. The Events Register The Events Register, together with its corresponding Events Enable Register generates the summary bit. Note that the Events Enable Register is common to all the Power Modules. The Events Enable Register determines which of the Power Modules Events may cause an SRQ. The content of the Events Register is cleared when read.
Handling SRQ and the IEEE488.2 Status Structures Usage Guidelines The Power On Retain or Initialize feature is another powerful tool for controlling the turn on behavior of the XMP 2600. 16 XMP 2600 Programming Manual rev. 1.
Basic Programming 3 Basic setup and usage Basic Programming This chapter guides you through the process of programming the XMP 2600 to provide power at the outputs of its Power Modules. Basic setup and usage Assuming the XMP 2600 is initialized at turn-on (or no advanced features were used before) it is possible to rely on the default setup of the XMP 2600 and use a very small and basic set of commands.
Basic Programming Output Setup The XMP 2600 has a host of features that enhance its usage. This section describes the parameters involved in setting-up the outputs of the XMP 2600 Power Modules. Overview of Power Module output rating output setup Each XMP 2600 Power Module is defined by its output rating (the amount of voltage and parameters current it can deliver). The user can use a Power Module up to its output rating, named Vmax and Imax.
Basic Programming Output control where can be programmed between the output setting value (Vset or Iset) and the output rating (Vmax or Imax) + 10%. When changing the settings of an output while using a manual setting mode for the protection thresholds, follow the guidelines shown here: For up programming, raise the protection thresholds before you raise the output settings. For down programming, set the new output settings before you lower the protection thresholds.
Current limiting schemes Basic Programming Issuing the OUT 0 command, globally disables the outputs of all the Power Modules. Turning the output on or off Use the OUT ,1 command to turn on the output of a specific Power Module. Not that only if the other conditions mentioned at the top of this section are met then the Power Module’s output will be activated. Use the OUT ,0 command to turn off the output of a specific Power Module.
Basic Programming Reprogramming Delay Linear foldback When the linear output foldback mode of operation is selected (using the FOLD ,2 command), when the output current of the Power Module reaches its limiting value, output voltage and output current are reduced (depending on the characteristics of the connected load) down to 0 volts and 30% of the set current (for an output short-circuit).
Basic Programming Reprogramming Delay To set the amount of Reprogramming Delay, use the command: DLY , where nn.n can range from 0 to 25.5 seconds. The normal value to use for the Reprogramming Delay period is 1.5 seconds. 22 XMP 2600 Programming Manual rev. 1.
Advanced Features 4 Workpoint window warning Advanced Features This chapter introduces some of the advanced features of the XMP 2600 and provides guidelines on the usage of those features. Workpoint window warning Power Modules of the XMP 2600 can monitor their outputs and warn the user if the output values exceed a defined range.
Workpoint window warning Advanced Features Note that the WHIGH and WLOW commands refer to both the voltage and current thresholds. Voltage mode example Lets say that the Power Module in channel 1 is to be set to provide 12V with a current limit of 10A. The voltage setting and, optionally, threshold values might be set using the commands: VSET 1,12 VHIGH 1,12.5 VLOW 1,11.
Advanced Features Load protection The events enable masks Registered Power Module’s events can be enabled to seep in thru the status structure (using the CESE command) up to the main status byte and the SRQ generation mechanism (use the *SRE command to set the events that will generate an SRQ). Using these events-enable masks and monitoring service requests generated by the XMP 2600 relieves the governing software from routinely checking the XMP’s or Power Module’s status.
Advanced Features Arm, trigger, sync and ramp The high level thresholds act similar to the OVP and OCP features (but use a different mechanism) while the 2 low level thresholds provide you with additional protection features: Under Voltage and Under Current Protection (UVP and UCP). Arm, trigger, sync and ramp ARM To ARM a Power Module means to tell the Power Module to store new output settings values (Vset, Iset, OVset, OCset and polarity) for future use without modifying its output.
Advanced Features Arm, trigger, sync and ramp Output on While this operating mode is selected, a trigger supplied to the Power Module will cause its output to be turned on. If the output of the Power Module was already turned on then it will remain on. To select this operating mode, send the following command: TRIG ,4 Output off While this operating mode is selected, a trigger supplied to the Power Module will cause its output to be turned off.
Arm, trigger, sync and ramp Advanced Features Output settle In this SYNC generation mode, a SYNC is produced when the output of the Power Module settles to within 2% of Vmax or Imax from the programmed Vset or Iset. A new SYNC signal is generated following any commanded change of the Power Module’s output, be it a new Vset or Iset value, a ramp operation or an output on/off state change. You can use the SYNC signal to synchronize external hardware to changes in the Power Module’s output.
Advanced Features Synchronization of operations While ramping its output, the Power Module uses, for the ramp calculations, a resolution much higher than the output programming resolution. This fact ensures that no calculation-induced errors will affect the produced output ramp. Ramping must not be combined with any foldback mode other than mode 0 (voltage/current operating mode).
Synchronization of operations Advanced Features Output on/off To turn on or off a group of Power Modules (or all of them) at the same time, turn on the Power Modules you wish to use (individually, using the OUT ,1 command) then use the global output enable commands: OUT 1 → global enable of Power Modules OUT 0 → global disable of Power Modules Other operations If you wish to command a group of Power Modules (or all of them) to perform a simultaneous change in their output, you can use the trigger mec
Advanced Features Synchronization of operations Using software (OPC mechanism) to serialize operations The Power Modules of the XMP 2600 generate an internal OPC (Operation Complete) event that informs the main controller when they have completed the current operation. The XMP 2600 has several commands and queries that can use that OPC internal event. One such command is the *WAI command.
Advanced Features Selective shutdown Selective shutdown XMP Power Modules are shutdown when they detect a fault. Since the XMP 2600 is mostly used in systems where several outputs feed the same load it is desirable to have other Power Modules shutdown together with the faulty one. The XMP 2600 provide its user with several methods of controlling Power Modules shutdown behavior. The following sections describe the way to control the shutdown behavior of Power Modules.
Advanced Features Selective shutdown A cleared bit (having a value of 0) defines the module to be “single shutdown”, i.e. no other Power Modules are shutdown when this one detects a fault. Shutdown on non-fault events In addition to Power Modules being shutdown due to detected faults, the XMP 2600 can shutdown modules on non-fault events such as: Errors reported by Power Modules (not including errors 7 and 8 that are major faults). Distribution lines dropout warning (sense warning).
