Post by risele on dynamic modbus devices ^{CODESYS Forge talk (Post)}
Have the same issue: I'm making a test setup for modbus devices testing and calibration. One is run for every possible address, and it starts with minimal request: if the device is found, it continue to work with it, otherwise it's set to Disabled temporary. Those state machines are running under FOR cycle, and disabled are just skipped. Every instance have its own timer for not running too frequently and a start delay, so the actual requests are separate in time. I also check not for a single error, but have some timer to allow one-two timeouts. The small program disables and re-enables devices temporary (manually, since i could not iterate over MB devices). VAR Reset:ARRAY[1..GVL_MB.MD_COUNT] OF R_TRIG; i:INT; END_VAR {IF hasconstantvalue(GVL_MB.MD_COUNT, 1, >= )} i:=1; MD_1.Enable:=GVL_MB.MDPortsEnable[i]; Reset[i](CLK:=GVL_MB.MDPortsEnable[i]); MD_1.xReset:=Reset[i].Q; {END_IF} {IF hasconstantvalue(GVL_MB.MD_COUNT, 2, >= )} i:=2; MD_2.Enable:=GVL_MB.MDPortsEnable[i]; Reset[i](CLK:=GVL_MB.MDPortsEnable[i]); MD_2.xReset:=Reset[i].Q; {END_IF} There is also program to re-enable devices periodically. METHOD ScanBus VAR_INPUT END_VAR VAR j:INT; (*block auto scanning if calibration is running for any device since it's data-reach process that should not be interrupted with modbus timeouts *) CalibrationBusy:BOOL:=FALSE; END_VAR CalibrationBusy:=FALSE; FOR j:=1 TO GVL_MB.MD_COUNT DO CalibrationBusy:=CalibrationBusy OR MD_Calibrate.AutoTesters[j].xBusy; END_FOR; IF CalibrationBusy THEN RETURN; END_IF tBusScanSchedule(IN:=(NOT tBusScanSchedule.Q), PT:=tBusScanPeriod); IF (NOT tBusScanDelayer.Q) AND (tBusScanSchedule.Q OR (NOT xFirstScanPerforemed)) THEN xBusScanBusy:=TRUE; MissingCounter:=0; xFirstScanPerforemed:=TRUE; FOR j:=1 TO GVL_MB.MD_COUNT DO (* MD_Calibrate is main calibration program. Identifiers - is array of State machines mentioned above Phase_Faulted is a state of Identifiers where I'm sure device is missing on the bus *) IF MD_Calibrate.Identifiers[j].state=eStateMDIdentifier.Phase_Faulted THEN MD_Calibrate.Identifiers[j].Rescan(); MissingCounter:=MissingCounter+1; END_IF END_FOR END_IF tBusScanPauser(IN:=tBusScanDelayer.Q AND (MissingCounter>0),PT:=tBusScanDelay*MissingCounter); xBusScanBusy:=tBusScanPauser.Q; xFirstScanPerforemed:=xFirstScanPerforemed OR tBusScanPauser.ET>=tBusScanPauser.PT; Also the GUI have buttons for each address possible that re-enables the device if required.

depends on if you use PFC200 SL from CODESYS store or the Wago target for the PFC. If you use the SL product you need to setup the interface by a plcshell command...

Have you looked at this? https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ It's not exactly what you're looking for, but I've been able to make some things work more efficiently using this library.

CODESYS runtime version 4.9.0.0 for your Pi. ssh user should be pi. This is for RasperrPi Os 32 bit. If you are on RasperryPi OS 64Bit use Arm 64bit SL product as Runtime.

You need to create a function around this function to check the dialogs you use in your program. That's the way i have done it.

I think you want to implement client side scripting? Maybe creating HTML5 objects is an option, because the JavaScript is executed on the client side. See html5

Post by installwhat on exception in system events handler ^{CODESYS Forge talk (Post)}
I've noticed that exceptions in system event handlers don't stop the runtime or call the exception handler. I've included a very basic example to demonstrate. It seems likely this is undesired but unavoidable. Is that the case? Is there any advice on the matter? Thanks

Well still similar questions remain. I don't know of "CmpRecoverySwitch" and the only thing google has to offer is your xml file. I think you'd need to provide a lot more info before anyone makes much effort here.
