How can I read data from an NJ301 or NJ101 OMRON PLC from node-red?
I am trying to use the "FINS Read" node of https://flows.nodered.org/node/node-red-contrib-omron-fins.
In the GitHub description https://github.com/Steve-Mcl/node-red-contrib-omron-fins says it works for NJ, but when trying to read a variable I get:
"Response is NG! endCode: 2108, endCodeDescription:Write Not Possible: Cannot change."
How should the node and the PLC be configured?
I attach the OMRON configuration. For the NODE-RED I followed the specifications in the webpages
