Hello sir, I have a question about what to do if you expect a json to come in. Is it possible to receive it in this function block? I know that siemens also has block to deserialize a list of bytes that is in the json structure. Our client wants to use this form of communication in there system. Regards, Briyan
When I toggle connect bit.... The status bit shows code 16#7002 I am stuck at this.....enable to publish msg....what could be the possible cause and solution of this.....
16#8620 error seems to be "Encoding of the received message could not be detected or is not supported". Are you sending your message through as hex? Or something like an ASCII JSON? Full error list can be found here in the "Libraries for Communication for SIMATIC Controllers" PDF download: support.industry.siemens.com/cs/document/109780503/libraries-for-communication-for-simatic-controllers?dti=0&lc=en-US Hope this helps!
Hmmm, my first port of call for a connection issue would be to re-issue the certificates and make sure they're configured properly in the PLC. 9 times out of 10, when I've had an initial connection issue its because I've made a mistake with the certificates.
How did you configure the connection of plc to internet physically did you connected a router to same switch?

Hi I got error 16#8730 and subfunction diagnostic says 5. Where could be a problem?
Do you have any one for siemens and a thingsboard instance?

I think the problem is in the "use router" part, how to know the PLC is connected to the network
ntp server ?!
