Post by sivakov on Change the default ssh port ^{CODESYS Forge talk (Post)}
Of course there is! =) just edit file/etc/ssh/sshd_config and restart ssh service. but you'll lose the possibility of runtime management through "update Linux", so there enother question - how to change default port in codesys it-self?

Post by timvh on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
You should only open de COM port once and then leave it open. This hCom should not keep on incrementing. (off course when you are done communicating, you need to close the COM port)

Post by joanm on Programmatically change the IP addresses of the Modbus TCP slave devices ^{CODESYS Forge talk (Post)}
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

Post by kevinl on RevPi Connect RS485 ^{CODESYS Forge talk (Post)}
I figured this out on my own with this logic: usually the Serial port on a Raspberry pi is on /dev/ttyUSB0 then you need to set linux.DeviceFile=/dev/ttyUSB in codesys you then must set com port to 1 so i assumed codesys subtracts 1 from the number and adds this to the filename... (in code it would look like this: var comPort : byte := '1'; linuxDevice : string := '/dev/ttyUSB'; filename : string; end_var filename := concat(linuxDevice, (to_string(comPort-1)); filaname then is /dev/ttyUSB0 RevPi uses ttyRS485 as Serial port so you must remove the last number from the name and set the com port to this number +1 i hope this is understandable ;-)

no parameter seems ok but RS485 does only work with CODESYS if the send/receive is determined by hardware as I remember correct

no config file is ok, the feedback is: your hardware must support this send/receive switching
