Additional DIO-Modules

Scope

The Commonplace Robotics control for the igus robolink robots comes with one digital input / output module with seven digital inputs (24V via Optocoupler) and 7 digital outputs (24V max 300 mA via reed relay). If these DIOs are not enough it is possible to add two further digital input / output modules to the control.

Mechanical Integration

Do not hotplug! Disconnect the control from the power source before changing components of plugging / unplugging cables!

• Add the bus extenders to the control. They have to be pressed in the C-Rail and pressed to the existing control beneath the Digital IO module.
• Plug the additional digital IO module
• Set the CAN ID with the selector on the front face:
  • First (already existing) IO module: 0 (this results in CAN ID 0x70 = 112)
  • Second (additional) IO module: 2 (this results in CAN ID 0x80 = 128)
  • Third (additional) IO module: 4 (this results in CAN ID 0x90 = 144)

Electrical Integration

Digital Inputs:

• Connect the ground pin (Output connector 1, to GND
• Supply 24V to one of the input pins
• Example on the left: 24V via switch to input pin 4
• Result in CPRog: digital input Din24 is triggered

Digital Outputs

• Connect the supply pin to 24V power supply
• The supply is forwarded to one of the outputs pins via reed relays
• Connect a valve or another component to the output pin
• Connect the component to GND to close the electrical circuit
• See the example with the lamp on output 5 on the left.
• In CPRog:
  • Reset and Enable the robot
  • Set DOut 25 to true to switch on the lamp
