Post by guilhermeleao on How to communicate 2 pcs that are using CODESYS ^{CODESYS Forge talk (Post)}
I need to connect 2 computers on the same network that are running codesys, so that they can receive and change variable values from each other. This connection must preferably be made using Modbus.

Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Post by rabaggett on Reading Named Pipes in Linux Is there a better way? ^{CODESYS Forge talk (Post)}
I have a Python program that will handle things in my application such as VISA over IP and Telnet control of instruments. I want the main control and HMI in Codesys. My problem is communication between the two. I have looked at several ways to accomplish this, and settled on having the Python program create two named pipes, one to send information to Codesys, and one for Codesys to send information to Python. The information would be packetized with \n for end of packet.. Seems simple. I think the named pipes method should work, but file reading in Codesys using the CAA file library starts to get difficult when the file is never ending, as in this case. Before I spend too much time making something that may be fundamentally flawed I want to ask. Is there a better way? Is there a way to read the file 'one line at a time' which might solve my never ending file problem? Thanks!

Do you think there'd be a way to turn this into a library? How would I2C_master be passed down to POU FBs?

Scan from "IP-Configuration" with PC connected to first EtherCAT slave and "EtherCAT" tick box ticked gives slave info. As does ticking the "Emergency" tickbox.

Thanks Edwin. I have reviewed the example and I'm doing basically the same when calling the methods. The recipe files are in the right directory. Everything looks okay but simply it doesn't work. May migrating to Codesys 3.5.20 will solve this?

Thanks @eschwellinger! So my settings look like this on CODESYSControl_User.cfg: [CmpWebServerHandlerV3] AllowFileTransferServices=1 CallVisuServicesDirectly=0 Sadly, is still asking for user and password as soon webvisu is loaded... Any clue? Many thanks!

Post by paulg on CODESYSControl_User.cfg - link to documentation? ^{CODESYS Forge talk (Post)}
Is there somewhere in the Codesys help files that generally details what configuration options are available for this file, and what details it logs regarding the configuration file? Or is that going to differ by libraries being used? Thanks!

you need to have an own task for the one wire and io update these slaves in an own low prio task!

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.

Post by eschwellinger on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?
