Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

Post by remcoborghuis on C0032 Error to type Pointer to IoConfigParameter

Hi All, I'm using codesys on a raspberry PI. I use V3.5 SP18 Patch 2 development system and codesys for raspberry pi 4.8.0.0. Sometimes when I build the project I get error messages C0007: Expression expected instead of ',' and C0032: Cannot convert type 'Unknow type: '!!!'ERROR'!!!" to type 'POINTER TO IoConfigParameter'. I can't click on the message to bring me to the fault. After I do a "Clean all" the build finishes successful. Anyone who can help me with this problem? Thanks! Remco Borghuis

Hi, you can take a look at https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html Maybe it helps.

Post by tvm on Cannot pass array of constant size to a function as a reference
CODESYS Forge

It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Update: I was able to successfully use the SysCom.lib. I had to install SysTypes2Interface library as well and wrote following code. Declaration hCom : RTS_IEC_HANDLE; pResult : POINTER TO RTS_IEC_RESULT; Implementation hCom := SysComOpen(ComSettings.sPort, ADR(pResult));

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5

I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

I'm having trouble getting started with the SysFile library. I tried copying and running the code found here: https://forge.codesys.com/forge/talk/Engineering/thread/f17c3d0e64/ Every time I try to run the file handle pointer returns: 16#FFFFFFFFFFFFFFFF <dereference of="" invalid="" pointer=""></dereference> I can see the file when I look in the Device -> Files window Any idea what I'm doing wrong?

Wow.... I missed this one in the manual - so there is a special syntax to invalidate a reference... Great :) Seems to work. (it's just mentionned in the examples line)... I've always assigned 0 to the variable, with := 0 - like setting a pointer to 0. In theory, that should work as well. Thanks!

Hi, I am trying to access active alarms in code(As alarm count variable updates only when we go to to alarm table frame in visualization). I wrote following code but it is not working: VAR iCountActiveAlarms : INT; parritfActiveAlarms : POINTER TO ARRAY[0..0] OF IAlarm; itfAlarmManagerClientAll : IAlarmManagerClient; END_VAR AlarmManager.g_AlarmHandler.GetActiveAlarms( itfAlarmManagerClient :=itfAlarmManagerClientAll, iCountActiveAlarms => iCountActiveAlarms, parritfActiveAlarms => parritfActiveAlarms); The Value is always 0. Please help.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
