Modbus Input Output Size

Post by ECNJAPR »

I have modified the RAP file for the virtual Modbus TCP Master and Modbus TCP Slave to have more Inputs and Outputs, but when I try to write in the register 33, I get an error. I modified the RAP file, saved the config-start, reset driver and reboot the device to make sure the configuration was loaded but it looks like the old 32 word input/output config is still running.
The communication between RevPi and my PC is running with writes and reads working as usual but the address above 32 are not usable which I need.

There is a video tutorial available that shows how you can create your own RAP file. Maybe you start with this and add your functionality step-by-step.
