Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work). In general: - Motion function blocks have to be called until they report 'Done', 'Error', 'CommandAborted' or a subsequent motion FB with BufferMode=Aborting is started in the current cycle. - Setting the Execute input to FALSE will not abort any ongoing motion of the motion function block. For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. I think the error SMC_FB_WASNT_CALLED_DURING_MOTION is only a follow-up (and misleading) error that results from the axis not being in operational state anymore (bus problems). Is there an error 'regulator or start not set' in the device log before the error 'motion generating FB wasn't called for at least one cycle'? Which error does the respective function block (Halt.ErrorId) report?

Post by simotion on Online view : code is scanned ^{CODESYS Forge talk (Post)}
If I do online monitoring of code in f.i. a function block, I cannot see if the function block is called or not. In software from other vendors you normally have an indication if the online code you are looking on is scanned at that moment or not. Is there a way in Codesys to determine in the online view if (parts) of the code are scanned or not? Thanks

Post by tvm on SEND_RECV_MSG function block on Schneider Machine Expert ^{CODESYS Forge talk (Post)}
Anyone else using the SEND_RECV_MSG function block for RS-485 communication on Schneider Machine Expert? I have had ongoing issues with it for several years, which Schneider tech support is aware of, but hasn't been able to fix. The latest version of Machine Expert (v2.2) appears to have broken some of the functionality altogether. I'd be interested in hearing from anyone else using this platform for serial communication.

Post by timvh on No source code available for this object ^{CODESYS Forge talk (Post)}
The message means that you (CODESYS) tries to open the function block, but this is not possible because the library which contains the FB is compiled. You either get this when you try to manually open the function block (while editing the application), but it could also happen that an exception occurs in the running application and CODESYS tries to show the location where it occured. If it happened in an FB of the compiled library, it cannot show this and you could get this message too.

Post by ellocco on Leitungsverzweigung mit einem existierenden Block (z.B. AND-Glied) zu verbinden ^{CODESYS Forge talk (Post)}
Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

Post by kumareasu on Persistent variable storage ^{CODESYS Forge talk (Post)}
Is there any function function block which can store the persistent variable in HDD/SSD immediatley. My observation is that the persistent variable is getting stored when we shut down or restart the system (Windows+ CoDeSys RTE SL ). the persistent variables are not stored in HDD/SSD, if I power off the system without proper shutdown. Seeking your feedback.

Post by snhatton on Can't open online view of FB instance from code editor, only from Device/POU windows ^{CODESYS Forge talk (Post)}
Good morning, Yes, this is a known bug that has been reported. For now, the only workaround is to open the function block instances from the device tree. Regards, -Shawn

Post by joanm on Function block method default arguments ^{CODESYS Forge talk (Post)}
The new TwinCAT 4026 will add those default parameters, as TwinCAT drinks from Codesys I guess that will be implemented soon (or maybe, it already is given what tvm says in the previous post).

I think you should use a piece of hardware in between your drive (pulse/direction) and the plc like for example Beckhoff EL2521 - so Ethercat might be to choice if you need CNC and SoftMotion. EK1100 and EL2521

not sure on which plc you are - there might be the option with: https://forge.codesys.com/drv/sm3raspistepper/home/Home/ but it is more or less Pi restricted and need additional hardware too I guess.

That is an output of the Function Block ModbusMasterRTU example: xIsConnected=> xIsConnected In this line the VAR ModbusMasterRTU.xIsConnected is written to VAR xIsConnected xError=> is writing to nothing here.

Post by timvh on Array of Program ^{CODESYS Forge talk (Post)}
You cannot create an array of Programs. Create a Function Block for this purpose instead of a program. You can create an array of FB instances and call each instance in a loop.

Post by rringo on Function block not autofilling ^{CODESYS Forge talk (Post)}
I am attempting to place a block and make it an Analog sensor. When I go to change the name like in the instructional video on youtube it does not give me an option to autofill the block with a known configuration. This is a problem I have in Codesys 2.5 and 3.5. Did I mess up the install of the program or need to install a library? Any help would be appreciated. https://www.youtube.com/watch?v=PkJYQeIUmIM&t=136s at time mark 2:15ish The first image is what I can do and the second is what the videos function autofills to.
