Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Yes, I tried to do what you put in the first code. However, I have a problem with that and that is that the inputs must be declared with the type. I have many data types running in my code (real, int, uint, bool) and I can't put them in the same function, another thing is that I need to instantiate that function for everything I want to write to the slave. You put a for to 200 but it means that it has to be the same data type and inside the array, but I want to get them individually. I'm struggling to do it in a good and efficient way like wago's E-cockpit does. in the first screenshot you can see, you simply type in value, change the package of things you want to write in value change and it does everything by itself automatically, without comparing any old and new values and even less having the need to activate a bool. , it is perfect.

You could create a DUT of the Type Union and add an array of 2 bytes + an Int. Then write the byte values in the array of the Union and read the Int. Or VAR iInt : INT; byHigh : BYTE := 2#1111_1111; byLow : BYTE := 2#1111_1111; END_VAR iInt := TO_INT(byHigh*16#100 + byLow);

This works for me in Schneider Machine Expert 2.2, which is based on Codesys 3.5.19. It did not work in Machine Expert 2.1, which was based on Codesys 3.5.16. METHOD PUBLIC Method1 : INT VAR_INPUT TestVar: INT:= 5; END_VAR Method1:= TestVar; PROGRAM SR_Main VAR TestFB: TEST_FB; Var1: INT; END_VAR Var1:= TestFB.Method1();

Post by tvm on multiply gives negatives ^{CODESYS Forge talk (Post)}
It's probably because you have an INT in the input to the MUL function, which will then try to output an INT as well. INT variables can only handle values of -32768 to 32767. Your value of 523000 won't fit in an INT, so it turns into an invalid number. Use a DINT. This is usually better for working with time values anyway, because time values are all 32 bit. Or if you can't, use INT_TO_DINT(gvlp.detectie_nalooptijd_s) in the input to the MUL function.

Post by spiessli on Objects in OPC UA Information Model ^{CODESYS Forge talk (Post)}
Hi, I have an OPC UA information model with objects defined in it. I can import the model and use the data types defined in it and create instances of these types. These instances are accessible at Root > Objects > DeviceSet > CODE[...] > Resources > Application > GlobalVars > OPC_UA_Symbols for created instances and at [...] > Programs > PLC_PRG for mapped instances. The object defined in the information model is accessible in UA Expert by the name I have defined in the information model (Manipulator) at Root > Objects > Manipulator. How can I assign values to the Variables defined in the object "Manipulator"? Cheers, spiessli
