Connection with PLC


I have connected the CB Series UR5 robot to a PLC as a MODBUS Client.

I am sending registers to the PLC using:

			modbus_set_output_register(signal_name, register_value, is_secondary_program)

I have set the frequency of the signal to 125 Hz from MODBUS installation tab.

But when I checked from PLC, I see the frequency is 1.33 Hz.

Any idea why this happens?

Also, is there any other way to communicate with PLC in much higher speeds?
