I have problem with modbus serial port on wago cc 100. I follow all steps in wago guide
for rs485 on cc100.
Wago cc 100 firmware: 03.09.07(21) (latest)
Nodered 3.0.1 docker image.
Modbus version 5.23.1.
Modbus device: IMI TA160 modbus valve actuator.
Guide i followed:
Here is error message i get from node-red console when doing a modbus read request:
./entrypoint.sh: line 14: 6 Segmentation fault /usr/local/bin/node $NODEOPTIONS node_modules/node-red/red.js --userDir /data $FLOWS
Im trying to read off register 0. Which should return me a value of 0. I have also tried to write to said register, but node-red still crash. I have also tried other registers to no avail.
I have to delete node-red-contrib-modbus to restart the flow.
There is 2 guides on how to use modbus rtu with nodered and wago cc100.
So far i followed this: Using RS485 port on CC100 with NodeRED
But maybe this guide is right one?
