Hello; Please tell us which model of Siemens PLC you are planning to use, a CPU from another manufacturer (or a Modbus simulstor) will gather much less replies from the Siemens forum. Siemens does provide complete documentation on all their automation products through this site, such as the communication manual for that relay (including Modbus RTU parameters and registers). This information can help you whatever hardware you have selected as Modbus RTU master. https://support.industry.siemens.com/cs/ca/en/view/109816798 In attachment you will find a sample of the Modbus registers starting at Modbus address 3xxxx, and accessible through Modbus Function 4. Hope this helps Daniel Chartier |
