Hello. I am using TI AM64x evaluation board TMDS64EVM. It has 8 leds connected via I2C to SoC.I wanna control them via codesys GPIO device. Is that possible? If so how I can do it. I had no problem installing codesys runtime, and running program on device. But when it comes to GPIO access, It couldn’t make it.

Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge talk (Post)}
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel

Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

A bit of work but maybe possible to make your own driver using "CODESYS Control SL Extension Package". Look at the "ExternalIoDrv" example. It is installed in "C:\Program Files\CODESYS 3.5.20.0\CODESYS\CODESYS Control SL Extension Package" when you install the "CODESYS Control for Linux SL".

I'd like to measure tool length using SW. How do I set variable from the accurate drive position when switch turn ON/OFF? Hopefully, I'd like to measure Z-Pos with M-Function in G-Code automatically, And I'd like to set it to G43 as tool length correction.

Probably best to call the FB continuously. So something like this could solve it: IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog := FALSE; fbOpenLatchSettingsDialog.xExecute := TRUE; END_IF IF fbOpenLatchSettingsDialog.xDone OR fbOpenLatchSettingsDialog.xError THEN fbOpenLatchSettingsDialog.xExecute := FALSE; END_IF TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog( itfClientFilter:= VU.Globals.OnlyTargetVisu, sDialogName:= 'visu_AlarmLatchSettings', xModal:= TRUE, pTopLeftPosition:= ADR(TopLeftDialog) );

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!

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

Hi, My problem was related to the behavior of the modulo axis, but maybe you will find something useful from what I write. The solution lies in path processing. Codesys offers a G-code analysis tool. Insert a CNC object into the project. The CNC settings object will be added automatically. By inserting appropriate processing modules into the CNC settings object and parameterizing them, you can test the behavior of the axis. When the effect is satisfactory, remember to add the module from CNC settings in the correct order in the processing path. Each CNC machine case is different. You need to spend some time to get your design tailored like an Armani suit. Good luck.

Thank you for your answer! I'm not sure, but it seems this is not what I am looking for. I attached three pictures. The first one is from the Codesys IDE. I use an Information Model to generate an OPC-UA server. I connected via UA-Expert, and there I see the URIs I would like to change.
