PLC goes to RED LED

[SimonGoldsworthy]

I attempted to compile and run your SCL code but it failed to compile as variables vhod1,2,3,4 are not declared anywhere (as previously reported by Ken M).

Variables Vhod1,2,3 and 4 are declared in the symbole table. Vhod1 is I126.0, vhod2 I126.1, vhod3 I126.2, vhod4 je I126.3 .

Ok it compiles, now how about how you were calling it ? what parameters did you pass and are you sure the instance DB was up to date ?

In the simbol table i wrote simbol name : Exercise FB1 FB1 and the ExerciseBD DB1 FB1.
var_input:
Dis_input01:bool:=false; // inputs set through the OP
........................
........................
Dis_input04:bool:=false;
End_var

var_output
vhod1:bool:=false; // inputs on the PLC
.
.
vhod2:bool:=false;
end_var

with the goto statement i was only trying to compare somehow the inputs of the plc and of op.

Is this what you wanted to know if not, then please be more specific.

 

[SimonGoldsworthy]

What variables did you enter as the passed parameters when you called the block ? (or did you not enter any but set the OP to write to the instance data block addresses that contain the function block's parameters ?)

Well i simulated it through the variable table.
