I am new to this forum and I am just beginning to us codesys.
I am trying to get communication between berghof EC1000 and roboteq 2130. I am using 232 serial port. I am using a program I got from the codesys store ( http://store.codesys.com/serial-com.html
). I am using Codesys v3.5 SP1 Patch 4.
My problem is that I can send one message through the serial port whit out any problems, but when I try to do it again nothing happens. Then I have to logout from the project and download it again to be able to send the messages again.
Can anybody please help me with this problem?
