Post by ggarcia94 on CANOPEN SDO configuration ^{CODESYS Forge talk (Post)}
Hello, I´m connected to two drives via CANOPEN. The connection seems to be ok. However, I´m not able to get the PDOs to work even tho they are configured as in the manual of the drives. Looking at the SDOs I´ve seen that for each PDO there is a "Disable PDO" SDO that does not exist in the manual or in the EDS file of the drives. This "Disable PDO" signal has the same Index and Subindex as another SDO used to set and enable the COB-ID of the PDO. I´m assuming this is normal but why is Codesys creating a "Disable PDO" SDO for each PDO and could that be the reason the PDOs are not working?

Post by nmcc on How to address visualization change with button press... ^{CODESYS Forge talk (Post)}
Hello all, I am extremely new to Codesys and to programming with these languages in general. I have an HMI panel with 8 physical buttons to the right side of it. I am trying to have these set to change the visualization to a specific screen which I have designed 8 of. I currently have "use CurrentVisu" enabled in the visualization manager. I also have input blocks with all of the buttons being directed to output blocks which I want to have as the switcher for the visualization. Picture is attached for what I have currently. This could be the wrong approach to this issue. Any help is much appreciated.

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Hello, I'm trying to understand the reason for the many errors on the EtherCAT master status page. If we set the cycletime to 1ms we see a lot of rxerrors and lostframes, but the send and recive times are quite good (see attachement). And the status of the EtherCAT bus is good (no other errors, all is green, slave has no errors) But when we set 2ms cycletime the lostframe errors are gone, but periodically increses rxerror counter (see attachement). The questions is, what do these errors actually mean and what we can do to get gid of them? Linux RT, imx8, Codesys runtime for ARM 3.5.21.10, Ethercat 4.10 Thanks

Post by artem1223 on Synaxis of library declarations in the ST ^{CODESYS Forge talk (Post)}
Codesys 3.5 17.30, plc - crevis GN-9373. I need to use RTC of pls for write in registers (need to check difference of writen 100 and 200 registers). For this i try to use SysTimeRtc (SysTimeRtc.SysTimeRtcGet) but its not working. After it i tryed to use SysTimeGetMs and something like this but still not working. Library? Mb but check project, SysTime with SysTimeRtc already, all what i know - already is here. Its my first try to learn ST (early used fbd and ladder, yeah), pls help with it. Mb problem with a syntaxis, but im not sure.

Post by baotthitawat on SCADA Systems Are Becoming Easier to Integrate With Modern Applications ^{CODESYS Forge talk (Post)}
One thing I’ve been seeing recently is that more industrial systems are starting to expose realtime SCADA data through APIs instead of keeping everything isolated inside the local monitoring software. This makes integration much easier for cloud platforms, mobile dashboards, AI analytics, and enterprise applications that need realtime industrial data. Instead of exporting reports manually or building complicated middleware, APIs allow external systems to access SCADA data directly in realtime. I think this becomes especially useful for applications like wastewater treatment monitoring, where operators need better visibility into alarms, equipment status, and operational conditions across different locations. Feels like modern SCADA is slowly evolving from a standalone monitoring platform into part of a larger connected industrial ecosystem.

Post by rik123456 on Alarmmanagement – Dynamic Alarm List ^{CODESYS Forge talk (Post)}
Hi, I had a question about alarm management in the CODESYS visualization. I am currently investigating to what extent the alarm visualization can be built dynamically. In my program, I have developed a motor block that is used for multiple motors. When the emergency stop of one or more motors is activated, the corresponding motors are displayed in the alarm list (see image). This works quite well. I achieved this by linking variables to a latch, after which a piece of code displays the motors that are in emergency stop. My question is: do I need to create a separate latch for each motor or can I use a single latch to display multiple alarms of a motor underneath each other? This would then look like this: Time…: M1 Emergency Stop Active Time…: M4 Emergency Stop Active

Post by timvh on library inside library ^{CODESYS Forge talk (Post)}
1) it should be possible to access the type SysTime in the project as A_Lib.SysTime. 2) you could add the SysTimeCore library to the library manager of your library (POU Pool). This might seem as a double library, but because of the placeholder resolution only one will be used. Then, in your library manager of your library, select the SysTimeCore library, right-click, select "Properties" and enable the option "Publish all IEC symbols ...." For more information about library development, you could follow our advanced training course in Ridderkerk. The next is scheduled for 24 and 25 June 2026 https://www.extendsmartcoding.nl/codesys-training/
