PAS600 + M251 data mapping table

[Alexander_Akulov]

Hello Team! We had a difficulties in reading data from PLC Modicon M251 to upper ECS PLC via modbus TCP/IP.

According to the project the ECS PLC should be connected to the M251 (as single data concentrator for the sensors) not the PAS600. So all the signals from all PAS600 will be re-mapped in new addresses in the M251.

The configuration is made in LV SMD.

We need to know which modbus registers we will read from M251.

Hello @Alexander_Akulov , 

If you need to know M251 registers related to LV SMD application, please check this thread:

hello @Alexander_Akulov ,

Not sure that PLC supports RSTP, for me ETH1 is a basic switch.

@Romain_Polette  has provided the right link, all "functions" are grouped by range of address in the PLC.

Idea to have the PLC is to get the alarming made by the PLC ( compute the various thresholds).

If you just need the temperature readings SMD is not mandatory.

Kind Regards

Hello @Guillaume_Evrard 

We have temperature measurements only. We need to send values in upper level to ECS. Which registers should we read from PLC itself in that case? 

Thank you in advance!
