Can a CAN bus IO module act as a controller? The answer is of course no! Because it does not have the master station control function.

Although they all have bus interfaces and integrate a lot of IOs, the CAN bus IO module has not been written into the control program.

Its task is only to act as an accessory for CANopen PLC, so that PLCs with insufficient IO interfaces have additional.

The IO port can collect information or output control commands in a larger range.

Whether it is an integrated CAN bus IO module or a combined CAN bus IO module, their working principles are similar, and we have already developed finished products.
