Your function block instance is not called, so the code is not executed to set the light on when the button is pressed.

Hi Guys, I am new to this forum and i would like to ask od anyone got communication with Siemens v20 vfd working via Modbus RTU? I followed many websites and finally got the communication working but have problema with read/write registers. For example if i try to read holding register 40011 which is accel time i get noth but when i set the offset 0x0000 en length 113 i get ale the registers. I cannot get speed control working. I read someth about stw (control Word) and hsw but have some problems to understand it en get it working. It would be really nice if someone could help me with it. Thx

Post by trusty-squire on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
If you are switching a frame based on the "Switch Frame Variable", then just use a variable that is accessible to your program to set your active frame. If you're trying to see which is the active visualization, then use the "CurrentVisu" variable. Note you'll need to enable this by checking it on in the Visualization Manager settings. If it's neither of those, you'll need to be more clear on how you're project is set up.

Post by atone on Set DeviceID of an IO-Link Sensor at Runtime ^{CODESYS Forge talk (Post)}
I need to be able to change (set) the DeviceID of an IO-Link sensor (see DeviceID.png) at runtime. I tried with both ProfinetCommon.PN_PortConfiguration and ProfinetCommon.IOL_PortConfiguration, but I get an error for both when I try to read the port configuration (see PN_PortConfiguration.png). Does one of those FBs is the right one for my purpose? Do I possibly make a mistake when assigning the parameter IOLD_ID/IOLM_ID?

Post by romrot on MS SQL Compact cutting off Database name? ^{CODESYS Forge talk (Post)}
I'm trying to use an fbMsSQL_compact function to read data from an SQL database. It works with some databases, but there is one database that I can't seem to get it to work on. It's set up the same as the other databases that I've tested with the only difference I see is that the name of the database is cut off in the status message. I'll get a message like "User: User logged out succesfully from database: 12345" But the whole name of the database is something like 1234567.

Post by wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

Hi Sir Kevin. May I know how you came up with this solution. Im a bit confused but I tried to put this. [SysCom] Linux.Devicefile=/dev/ttyRS48 (remember, no 5 at the end!) then set com port in codesys to 6. It also works for me but want to know where did you get this. Thank you.
