Post by seler on Custom button with output status ^{CODESYS Forge talk (Post)}
I did some work around by adding IN switch on top of OUT bulb picture(SwitchImage) and setting IN switch button to invisible but this is not quite elegant. How to combine it to one visu element?

Post by tristan on Textfield display problem ^{CODESYS Forge talk (Post)}
Hello Tim, I am using CODESYS Visu V4.8.1.0. It works when I turn off the "Support client animation and overlay of native elements". But if I do that, dialog box moving and other options are also disabled so it is a bit problematic. Thank you for helping.

No that is not possible for function blocks, although it is possible to that with methods and functions as you see in your second pic.

Were you able to figure out if it is possible to change the Application/Product URI of your server? I am having the same problem.

Hi, It was my fault. I was using a REAL variable instead of INTEGER. Sorry for posting this.

Post by timvh on Alarmmanagement – Dynamic Alarm List ^{CODESYS Forge talk (Post)}
Probably best to create an alarm template for your motor function block. Then automatically the alarm manager can be filled with all the alarms for all instances of the motor function blocks (based on the created alarm template). See: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_cds_obj_alarm_group_template.html

I updated the runtime to CODESYS Control for Raspberry Pi SL 4.22.0.0, SDK 3.5.22.30. Same outcome as before. Now I study if migrating to PFC100 is ok or to change to Siemens PLC because of this issue.

What do you think about having an AI Agent specialized in ST programming in Codesys? I see this saving hours and hours of work for those who program on a daily basis.

It's already fine to use, with help of exporting/importing as PLC_Open, at least CODEX is good in editing directly at XML and/or providing changes description separately.

Downloaded and installed edge gateway 4.19.0.0. Unfortunately same behavior: "Control for Linux SL" NOT shown in drop lists on either "Deployment" Tab of tool "Deploy Control SL", or as "installed packages" on "Operation" tab (only "CODESYS Edge Gateway for linux" is shown).

Am I alone in this? Is this a known fault? Should I look for the reason of the lacking update option for "Control for linux SL" in my system or is it a potential fault in the codesys system?

Post by egr99 on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
Hi there, Read the above description and experienced the same: Reading coil/discrete input/input register/holding register doesn't fill the mapped I/O variable. Any suggestions? Defined (see attachment): - Ethernet (with parameters according to the used Ethernet adapter of my Windows 11 laptop) - -Modbus TCP Client - - -LOGO231 as Modbus TCP Server - - -WS242 as Modbus TCP Server (WaveShare Modbus TCP <-> RTU converter) - - - -WS242_01 as Modbus Server, COM port (slave-id 1 RTU) - - - -WS242_03 idem (slave-id 3 RTU) - - - -WS242_11 idem (slave-id 11 RTU) Writing coil/holding register works from a mapped I/O variable works fine. Verification of Modbus traffic with WireShark: QUERY to and the RESPONSE of all slave-ids are correct Status of all defined is CONNECTED, RESPONSE_SUCCESS, RUNNING etc. Request counters increase with expected frequency. Error counter = 0. (To have all counters works fine I had to change Modbus TCP Client's parameter OptimizationON to FALSE). LOGO231 works fine: values in mapped I/O conform expectation WS242 without Modbus Server, COM port and with defined channels (for only 1 slave-id possible) works fine. PLC Settings: Update I/O while in stop: I see xBusy changing from FALSE to TRUE and vice versa. Always update variables: Enabled 1
