I'm trying to figure out how to use the WAGO 750-651 module for serial communication in Codesys.
I am already using the onboard serial port and this works quite well.
Judging by the contents of this thread:
l viewtopic.php?f=11&t=8418&start=15 l
It seems that it is not possible to access the module as a COM port like in Codesys 2.3?
Is this correct? Or could someone help me getting it to work properly?
Thanks
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
If you asking for Codesys V2.3 where you are refer to the wago version codesys runtime. If i not mistake to use the com module on wago there is separately library you need to use.
you may straight ask the library file from wago directly, if you can't get the library file just let me know. i'm try get from singapore wago for u.
Thank you

I was asking how to do it in CoDeSys 3.5, not 2.3.
Wago provides good examples and documentation for 2.3, but unfortunately not for 3.5
I did however manage to get it working.
It seems that the serial port isn't exposed in CoDeSys 3.5 as a port, but rather you have to use the control and status word along with the buffer to send data.
I made small program in SFC to do exactly this, it will take a string and transfer 3 bytes at a time while manipulating the control word correctly.
