I´m using Codesys 2.3 with an 750-880 PLC and trying to access Wago I/O modules 750-430 and 750-530 by BYTE/WORD variable (or maybe an array), unsure if it´s possible or maybe i am doing it wrong!
The DI has adress %IX8.0 to %IX8.7 resp. DO %QX4.0 to %QX4.7 whitch is an BYTE, is it possible to write/read an BYTE variable to the output resp input, or maybe assign it to and BOOL array, if so what would the approche be?
I have made an declaration of
bTest AT %QB4 : BYTE;
And then trying to do
bTest := 123;
Even tryed just declaring
%QB4 := bTest;
But unfortunately it does not work, both options get no build error but the I/O module does not respond.
I even tried to move "bTest AT% QB4: BYTE" to Global variables but it makes no difference either.
I am unsure if this works in Codesys 2.3 and/or 750-880, since i do not see the %QB4 under the device in the PLC_config tab?
Any pointers to doing this the right way would be appreciated!
