750-838 /021-000 CANopen programmable field-bus controller DE-9
10 kbit/s to 1 Mbit/s, digital and analog signals;
Program memory 640 KiB, data memory 832 KiB

The programmable field-bus controller for CANopen combines the functionality of the CANopen field-bus coupler with the functionality of a programmable logic control (PLC).

Programming of the application is done with Wago-I/O-PRO 32 in accordance with IEC 61131-3, covering all five programming languages. The programmer can access all field-bus and I/O data.

Three different memory versions are available:

  • 128 KiB/64 KiB program/data (750-838)
  • 256 KiB/192 KiB program/data (750-838/0020-000)
  • 640 KiB/832 KiB program/data (750-838/0021-000)

Characteristics and use:

  • The use of decentralized control can better support a PLC or PC
  • Signal pre-processing reduces field-bus transmissions
  • Complex applications can be divided into multiple tasks
  • Tasks can be prioritized
  • Peripheral equipment can be controlled directly, resulting in faster system response times
  • Programmable response in the event of a field-bus failure
  • Simple, self-sufficient control
