Hello, Hope you are well.

I have a question regarding MODBUS Master CP341 RS422 / 485 interface (6ES7341-1CH02-0AE0). We are using a Modbus Master with a number of Schneider Electric SEPAM-40 slaves. We are reading this data with the S7-400 CPU through ET200M (PROFIBUS). 

We are able to read values ​​well. T he challenge is; the values ​​on the S7-400 CPU appear to update after 75 seconds. This is too long. We have checked the values ​​on the SEPAMs and they update almost immediately?

Just wondering what might be the problem? Is it possible to change the update cycle? Is there anything else we can check?

Thank you.

Hello Kiiza,

you post in the wrong forum. This here is the german-speaking part of the forum, not the english-speaking part.

Will you post a new topic in the english forum or should I suggst the moderator to move your topic to the english forum?

Thank you. 

Let me repost it in the English forum.

Closed cause question posted twice.

The second thread with the subject MODBUS RTU UPDATE CYCLE is published within the conference Communication / Networks.

Best regards
