Hi all I’m getting these errors in docker logs when running the container - container keeps trying to restart. Does anybody know why? Thank you Best Chris PORT: 502 MAX CONNECTIONS: 5 OPERATION MODE: 0 MODBUS DELAY MS: 0 KBUS CYCLE TIME MS: 50 KBUS PRIORITY: 60 start init daemons dip-switch not found in /sys/devices/ INFO: PROFIBUS DP device “UIO\_DPC31\_XINT” not available start kbusmodbusslave verbosity level is 7 Not running in background kbusmodbusslave running… ADI Device[0]: libpackbus Found kbus device on: 0 Modbus: Wait for KBUS to be initialized KBUS open device failure.

Have you disabled the runtime ? Is the K-bus properly running (end module present, etc…) ? ---

runtime is disabled, yes we use Controller Type 751-9301 without KBUS docker container cannot run without KBUS? ---

Docker can run without K-Bus, but you are using pfc-modbus-server. As its name says, this container is made to provide kbus IO’s to Modbus server on a PFC. It has no purpose on CC100. What do you want to do ? Provide IO’s to Modbus or to another Containerized application ?

Thank you for the links. We would like to use RS485 (X11) interface on CC100 (751-9101) as Modbusmaster and read the attached energy counters (879-3020) using the Modbus interface. ---

Well in this case forget about pfc-modbus-server.

thank you, I’ll have a look do you also know about doing this in pure python? ---

I’ve only used PyModbus for TCP communication but it looks it can handle serial communication as well. You should mount the /dev/tty serial port like it’s done in the Node-RED example.
