I am using device, which is communicating over 485 with protocol MODBUS. I’ve wanted to replace my old gateway with this WIZ108SR, but it’s not working. On osciloscope I can see, that some data come from WIZ108SR if I try it with test program, but device is not responding. Probably he doesn’t recieve correct data, but I don’t know why.
The WIZ108SR product offering only ‘Serial data transfer to Ethernet’ functions (and vice versa function).
Is the ‘old gateway’ has function for MODBUS protocol data format generator?
Unfortunately, I guess you have to find a different solution like Modbus-TCP supported gateway device.
WIZnet doesn’t have the appropriate Modbus-TCP device solutions.
Thanks.
