Dear All,

I am trying to establish connection between Siemens S7-1215C DC/DC/DC and OWEN PLC 110 (http://www.owen.ru/en/automation_systems) through Modbus TCP. Siemens S7-1215C is client and OWEN PLC 110 is server.

First of all I have tried to connect OWEN PLC 110 with Universal Modbus OPC server (OWEN is server) in order to identify the adress of the registers. Connection was succesifully established. I could read and write bits and words. Please see results: Безымянный22.JPG

So now it is difficult to do the same with Siemens and OWEN PLC 110. I want to read and write the same reqisters/bits in Siemens (Client). Please see attached configuration: Безымянный

My question is how can I establish configuration if configuration OWEN PLC 110 with Universal Modbus OPC server was right. I have got results. Please see attached configuration for two bits: Безымянный1 and two words: Безымянный2. 

OWEN PLC 110 info: 

PLCInfo

PLC model MODEL PLC 110-30 

Binary  VERSION 0.2.49 

Need Target version >= 3.04

IP 192.168.0.3

GATE 192.168.0.1

MASK 255.255.255.0

I suspect that we have got problems in Siemens as all configuration in OWEN PLC 110 have been checked through Universal Modbus OPC server. Sorry that all attachments are in russian. Please advise how to configure Siemens S7-1215C  to do the same considering the configuration in Universal Modbus OPC server.

Thanks,

Arif
