Hi, these are the components. -TIA Portal V15 -Siemens S7-1511-2 PN -RTU540 540CMD01 -Analysers I am new to this and I have data coming from the Analysers to RTU. I'm told that I can manage to receive data from RTU to SCADA directly. But instead, I want to communicate RTU and PLC and I want to read data in TIA Portal. I wanted to use MODBUS TCP protocol for this. RTU Slave ID: 255 RTU IP: 172.16.4.2 Subnet Mask: 255.255.0.0 PORT 1- PLC IP: 172.16.4.50 Subnet Mask: 255.255.0.0 (Connected to RTU) PORT 2- PLC IP: 192.168.0.2 Subnet Mask: 255.255.255.0 (Connected to PC) PC IP: 192.168.0.50 I have given my MB-Client details in attachment. No particular error, "STATUS" stays in "7002" as it means connection established. But no data is sent to PLC, "BUSY" is permanently false. I used "MB_MODE" as 0 and also 103. I changed "MB_DATA_ADRR" to 400011 when "MB_MODE" was 0 and "MB_DATA_ADRR" to 11 when "MB_MODE" was 103. None worked. In RTU Config panel, I chose 03:Read Holding Registers option and gave Adress:10 for a data which as coming directly from Analyzer. Thanks for any kind of help, Attachmentsiemens.zip (33 Downloads) |
