  1. Hi, Thanks for your answers. I read the relevant help topics, and I tried with different settings combinations, for example, the time out, the baud rate. I found in the forum a program uploaded by Emil, which configure the Jazz PLC as Slave Modbus with RS232 Protocol, but I changed to RS-485. I'am using SCADA/”Indusoft” and, NPort 5150 as a protocol converter from RS485 to TCP/IP. In the Scada the configuration of the driver is Modbus TCP. I have a problem when the program tries to communicate with the PLC. The error is TIME OUT, but I have a method to know if the Nport and the Jazz PLC communicate. The Nport has a program with which, it monitoring the RS-485 port. The Nport reports 12Tx 1 Rx. This is the reason for what I asked previously for the RS485 connections. Thanks, Regards.
  2. Hi!!! Thanks, my problem was the intarface. I used a USB to Serial Converter, and it had hadware problems, but i tried with other computer, and the PLC works nice. Thanks. Regards.
  3. Hi, I have a problem with commnunication, I try to connect a Nport5150 to Jazz PLC R31 wich has a MJ20-RS; but I have a problem with the connections, because the Nport has 3 pins ( Data A, Data B and "GND") and the MJ20-RS only has 2 (Data A, Data B , my question is, where can I connect the GND terminal? And finally, i need help to acces the database of the Jazz PLC with MODBUS, i mean to the headers of MODBUS (eg. 0X:0, DW:10) I'm interesting only in the Jazz PLC R31. PD. I have problems with my english, I'm starting to study, that's why I write as short as possible. Thanks, Regards. Adrian G.
  4. Hi, I have a problem with JazzPLC, I can't download a program. I tried with different RS-232 configurations,but none works. The PLC is a JZ10-11-R31,and I try to connect the PLC and the PC with an MJ20-RS but it doesn't works. Then, Icheck the cables and connections and they are corrects. I hope youcan help me. Regards
