Technical support / Using NANO-10 PLC as modbus gateway
« on: July 11, 2016, 07:17:53 AM »
Hello,
I'm working with a Nano-10 PLC on a project, where I must to access a third party device by remote TCP/IP connection. Nano is connected to this device through RS-485 port. Remote connection has to be done through modbus ASCII protocol, and I was reading chapter 19 of Nano's manual, and says PLC works as Modbus gateway, but repeating only RTU commands. I was trying to do this using 502 port and PLCs IP. Connection seems to work but communication fails because of the RTU-ASCII differences.
Is there some way to use PLC as gateway but through ASCII mode?
Best Regards,
Alberto
