Standard Operations
A set of functions is available to set the error and warning status of output modules. Each
of these functions requires a minimum of 2 (or 3) parameters and allows a maximum of
32 parameters. In calculations all functions take the value of first argument A as the
function result, so the use of these functions does not affect the calculated value.
Table 26 Check functions to set errors and warnings
Range Error RNG(A, Min, Max) When A<Min or A>Max:
Error <E4> “RANGE FUNCTION” is set to the executing card
Range Warning rng(A, Min, Max) When A<Min or A>Max:
Warning <W1> “RANGE FUNCTION” is set to the executing card
Conditional Error CHK(A, X) When X is true:
Error <E3> “LOGIC FUNCTION” is set to the executing card
Conditional Warning chk(A, X) When X is true:
Warning <W0> “LOGIC FUNCTION” is set to the executing card
