Docker conflict with Wago PLC 8212 with codesys project

Hardware and Linux
1

Hello,

Environement
Codesys 3,5,19.7
PFC wago 8212 FW26

I installed
docker on the sd card
influxdb and grafana on the linux of the plc.
There is a codesys project with webserver running in the PLC

After few seconds after succesful download the RUN led flashes red.

After a stop and reboot of the PLC WITHOUT the SD card , the project run well.

I’m really intrested to use grafana with influxDB , but without any support when a conflict occurs , I prefer to use only codesys objects like curve, and Cartesian XY chart

When displaying values with Cartesian XY chart it’s not possible to have the date and time of the barchart of the considered point.

I hope that in a next version of codesys it will be present.

Perhaps somone knows a trick ?

Soo, i’m looking for someone that knows well linux, grafana , influx db , codesys to learn how to built a project with wago plc , that will make a grafana dashboard to display barcharts of counters.
Make me an offer , I will pay for it. $$ (german , English or American : no problem if you don’t speak too fast.)

Remote work possible, with anydesk or teamvwever

In Codesys FW26 docker is available and already installed.
You should really look into running both InfluxDB and Grafana in Docker containers - not in the “linux of the PLC”.
And to “push” data to InfluxDB, I prefer Node-RED (also running as a docker container).

It seems that Codesys runtime stopped the application. Go to WBM and check logs and show us which exception it throwed. Runtime has higher priority, so linux should kill influx first :wink:

Hello,

here is the runtime log file and the exception issue.

runtime_log.txt (2.3 KB)

I installed docker on the “linux” and then moved it to the sd card .
after i dowloaded the containers influxdb and grafana and node_red too.

here is a screenshot of the diffrents containers

I dowloaded the codesys example xy cartesian chart overlamping and it’s not more simple.
It’s a pity that there is no possibility to have a X axe with time or timestamp

thanks for your help.
