system.serial.openSerialPort() problem

Hi! Have the same problem again. … 72&t=11487

Ignition 7.6.7, x32
Serial Client Module version 1.6.7 (b2014082615)

So did the module suddenly stop working, or did something in your set up change?

Module still running I think.
Just designer is closing and I should start it again.

You’re probably going to need to contact support on this. There isn’t any thing that should have made it stop working, so they’ll need to work with you to see if some system update caused a problem.
