Hi, I have S7-200 Smart PLC and Rosemount™ 370XA Gas Chromatographs both are communicating on Modbus 485. I am able to establish communication between both controllers. I am able to read integer data type [9013 to 9036]. When I tried to read data from Floating point [7134 to 7145] then I am getting following error.
When I checked the Rosemount GC with Modbus Scan I am able to read I am able to read integer data type [9013 to 9036]. When I tried to read data from Floating point [7134 to 7145] then I am getting error. But in Modbus Scan when I change the Transmission Mode from STANDRAD TO DANIEL Mode then I am able to read the data from Floating point [7134 to 7145]. For Reference please find the attached Rosemount Controller manual. Please let me know to read floating point data type. Regards, Yogendra AttachmentGC_comminication.pdf (208 Downloads) |
