Hi,
I have an Rx3i IC695CPE310 and I need to be to read/write to the cpu registers (4xxxx / %R) using modbus.
It look like the plc is set to a read only mode and I cant find any information if it is possible to set the plc to a writable mode.
I have set the option 'Modbus Address Space Mapping Type' to 'Standard Modbus Addressing' using Proficy Machine Edition. This enables me to read the plc registers just fine. How ever this option does not enable writing.
Could anyone let me know if this is possible to achieve on a CPE310 and which settings to enable?
Regards
Ryan
P.S. to give a bit more information on the specific application. I need to pull information from the plc into our bespoke web applications. I am currently using a library in java to pull memory value from older plcs in the facility. I am also testing the modbus read/write using a modbus master simulator called 'Radzio! Modbus Master Simulator'
