MP370 profibus communication

Import-User-1 Posts: 3609 Rating: (29)	I have in the plant the OP35 panel which we need to be replaced with the MP370. OP35 is connected to S5 PLC via profibus. I've converted the program from OP35 to MP370 by ProTool v6.0 SP2. MP370 Panel is working correctly when it is connected to PLC by serial cable but when I connect it on profibus I don't have a communication with PLC. At the OP35 parameters were set like this: Driver: Simatic S5-L2-DP V6.0 CPU type: S5 115U CPU944 OP address: 4 Interface: IF1B Baud rate:500 On the MP370 I've set parameters like this: Driver: Simatic S5-DP V6.0 OP address: 4 Interface: IF1B Baud rate:9.6 Block lenght:Clas B small. I've tried to change the position of switches on the back side of a MP370 (like it is written in the manual) but it still doesn't work. Can you tell what is the problem? Would the upgrade of PRoTool to SP3 helped in something? Thank you!!

Because the MP370 is a Windows CE device. If you use profibus select a baudraut of 12Mbaud. What you have to watch out for is that several functions are resolved in a different way in the MP370. I have made a configuration with MP370 and CPU945 .It runs perfectly. Best regards, Andre van Gijsel
