IQAN-MD4 3 3 Product description Product description IQAN-MD4 The IQAN-MD4 is a family of combined display and bus master modules capable of running applications created by IQANdesign software. Built on a 32-bit platform the units have large computational power and is capable of controlling large applications. The IQAN-MD4 module. System overview The master module, IQAN-MD4, is the central unit in the system, or in the case of a multi-master system, one of the central units.
I/O 3 Product description I/O +BAT CAN-H -BAT CAN-L +RTC CAN-H +VREF MD4 CAN-L CAN-H CAN-L ETHERNET PORT 0 CAN-H CAN-L PORT 1 Voltage inputs The IQAN-MD4 module has two (2) voltage inputs VIN-A andVIN-B for connection of 0-5 Vdc signals. These inputs can be configured as digital inputs for reading switches. Voltage inputs and digital inputs share positions, see below.
Communication 3 Product description Communication The communication interfaces are used for uploading/downloading applications, connecting to expansion modules, connecting to cameras or diagnostics. CAN related functions The IQAN-MD4 uses a CAN-bus (CAN = Controller Area Network) to communicate with IQAN expansion modules and other systems. The CAN-bus is a robust communication protocol that is widely used and well proven within the automotive industry. The unit has four (4) CAN buses, CAN-A thru CAN-D.
Internal diagnostics 4 4 Safety Safety Internal diagnostics The module performs a number of self-checks that improve safety. Checks include monitoring of voltage supplies, checksums on memory and a watchdog that monitors software execution. The module is using a real time operating system which supervises software execution. If a critical error is detected, the module is stopped, with CAN-bus and outputs off. CAN-bus interruption The IQAN modules communicate on a CAN-bus.
Mounting the module 5 5 Mounting Mounting Mounting the module The IQAN module should be mounted according to the following instructions: Dashboard or panel assembly When installing in a dash or panel the recommended panel thickness is 1.0 - 3.5 mm. Use M4 screws to attach the supplied steel clips.. Panel mounting the IQAN-MD4 Ball or tilt/swivel mount The option to use ball mounting or tilt swivel mounting for display position flexibility is made possible by using Parker’s aluminum bracket.
Mounting the module 5 Mounting Mounting considerations N OTICE IQAN-MD4 shall be positioned in the machine per the following instructions: • The unit is designed for outdoor use. Position the unit in desired location and make sure that it is not exposed to mechanical damage. • The connectors on the reverse side of the unit should be accessible. • Position the unit so there is no risk that the cabling can be folded, crushed, worn or damaged in any way.

Supply voltage Supply voltage Before any installation of the IQAN system can take place, make sure the ignition lock is turned off and the battery is disconnected. Emergency stop Make sure an Emergency Stop disconnecting the power supply, is easily accessible at any time. The figure below shows how to connect the emergency stop. Connecting of Supply Voltage The supply voltage, should be within the operating interval, see Appendix A. Connect the supply voltage to +BAT and -BAT.
Addressing Addressing IQAN-MD4 use of an ID-Tag In IQANdesign 3.0 and higher software, more than one IQAN master module can be used together in a multi-master system. The master modules are each given a unique address by using an ID-Tag. The value of the ID-Tag identifies the master and will enable a single project application to be loaded into more than one master module over the CAN bus. The functionality needed for each master is loaded based on the ID-tag address.
Diagnostic interfaces Diagnostic interfaces IQAN software includes many tools for tuning, measuring, accessing logs and otherwise checking the performance or troubleshooting your control system. To use the diagnostic tools with an IQAN master module you may choose between different ways to connect to the unit. CAN diagnostics connection One of the CAN buses of the IQAN master module may be dedicated for diagnostics.
Video input Ethernet diagnostics communication The "A" (C3) Ethernet port is used for diagnostic communication or uploading and downloading project files using IQANdesign/IQANrun. On port A, the IP address is automatically assigned using DHCP. It is recommended to use an environmentally sealed panel mounted RJ45 connector for easy access. Parker part number 20077785. Video input The IQAN MD4 master modules are capable of showing video inputs from an external source.
Video input Analog Cameras It is also possible to connect an analog camera by routing the video feed through a video server with ethernet connection. In this case, it is the video server that needs to have the correct IP address set.
Reference voltage, VREF Reference voltage, VREF The IQAN module is internally equipped with a voltage regulator to generate the reference voltage VREF. The standard reference voltage will feed different kinds of sensors and potentiometers. On the IQAN-MD4 there is no -VREF pin, instead the -BAT is used as -VREF. To get the best result, connect as close to the connector as possible to minimise voltage fluctuations. In connection examples that follow, -VREF will refer to the -BAT pin.
Voltage inputs Voltage inputs Connecting sensors to the voltage inputs The sensor signal range must be 0-5 Vdc. To detect signal errors such as short circuits or interruptions the active signal range be within 0.5-4.5 Vdc. [V] 5 Error detection range Active signal range Error detection range 0 t Active signal range. The current consumption related to the voltage input is negligible.
Voltage inputs Connecting a 2-wire temperature sensor to voltage in When you connect a PTC (positive temperature coefficient) temperature sensor you may need to use a pull up resistor on the input signal. Please check the technical data for your specific temperature sensor. EXAMPLE Connect the negative terminal of the temperature sensor to -VREF, and the signal to VIN-X. The pull up resistor will be connected between VIN-X, and +VREF.
Voltage inputs Connecting switches to the voltage inputs using +BAT It is recommended to connect system voltage +BAT to the input through a switch in order to reserve 5Vdc VREF for sensors and potentiometers. EXAMPLE Connect the positive and negative terminals of the switch to supply or the unit’s +BAT, and DIN-X, respectively. +BAT IQAN module DIN-X switch Connecting a switch to DIN-X and +BAT.
Directional pulse count input Directional pulse count input Connecting a directional pulse count channel (DPCNT) The DPCNT is a physical analog input. The directional pulse count input channel is used to count pulses. It is bi-directional, which means it can add and subtract pulses. The DPCNT is primarily designed for input from an encoder wheel. For maximum frequency, see Appendix A.
Low-side digital outputs Low-side digital outputs The low-side digital outputs are designed to drive small loads, e.g. lamps and buzzers. Low-side digital outputs work by grounding a signal through the module. See Appendix A for maximum loads per output. EXAMPLE Connect the lamp to the low-side digital outputs using a DOUT(LS) position, and the +BAT, as supply. +BAT IQAN module load DOUT(LS)-X Connecting a switch to DOUT(LS)-X and +BAT.
