Hello m.shoaib khatana; We have worked with many Profibus-DP to Modbus RTU converters, generally the selection depended on what product was available locally and fast... Generally these gateways act as Profibus-DP slaves (your PLC is then a DP-master) and on the Modbus side they are masters 9so they can request data from the Modbus RTU slaves) We have had no problems with products from Moxa, Anybus and Hilscher in the past, but there are many manufacturers of such products on the web. Here are some links from the ones we used: www.moxa.com/product/MGate_4101_MB_PBS_Series.htm www.hms.se/products/products.asp?PID=140&ProdType...gateway NT 100-DP-RS - Hilscher Gesellschaft für Systemautomation mbH Another option would be to use a CP 341 with a Modbus RTU loadble driver to act as a Modbus master to your multimeter, and collect the data directly in your CPU. There aremany threads available on the subject in the forum. See the following links: 6ES7341-1AH02-0AE0 CP 341 RS232C (V.24) SIMATIC S7-300/S7-400 Loadable Driver for Point-to-Point CPs: MODBUS protocol, RTU format, S7 is master |
