Your are right. I have changed to 9600 and the comunication worked, but then when I downloaded the program with the new paramaters the on-line connection via serial and TCP/IP, now its not working and I think that it is because the baud rate. I test in another PLC that was with the same program but with other baud rate (a greater one) and the on-line connection worked. Now I can't conect with the PLC to change that... You have any ideia what can I do now? I have already try to connect with a cable to serial connection and reset the PLC but that isn't working. The MB 107 is for simulate the SB2, just for test.

Hi everyone! I'm trying to comunicate my PLC with a Energy Analyzer by the protocol MODBUS RS485 to read some registers. I configured the program with this parameters: PORT 1 (COM1) I configured the energy analyzer with the same parameters. To read the registers : I'm using the V700, and change the DIP Swtich to RS485. Even after that all, isn't comunicating. Is importante to say that the energy analyzer is comunicating with PCs, so I don't think that the problems is with him. Can you help me understand what may be happening? Thank you all
