v1210 losing touch functionality

[curtharrington]

Hello,

While writing a program and downloading it on the v1210, I came across a issue that I feel needs attention. I have a port 3 installed in the display to support a modbus network(pretty typical practice for my company). After some testing I plugged in my modbus network into the port 3 and lost all touch capability. I cycled power, redownloaded the application, initialize and reset, disconnected the modbus and still could not use the touchscreen. I took the port 3 out of the display and then powered the unit to find the touch screen worked properly, I grabbed a new port 3 (right out of the box) and installed it, lost touch capabilities again. I downloaded a different program (Which we have working in the field) and still lost touch functionality with the port 3 installed, our test v1210 has been working for at least 3 months with no issues until today, has anybody else run into this?
