If Diag Status Code is selected, then the third parameter is New
Status Code. You can define your own status codes in your
diagnostic routines, but PointeControl does automatically
record I/O errors (see above).
The value of Diag Status Code may be an Input/Memory/Output
tag, a literal numeric value, or some other logical expression
that is evaluated every time the block is executed.
To configure the Diag Status Code parameter, click the
button to open a standard
Build Argument
dialog.
o
If Error Status Bit is selected, then the third parameter is Error
Status Bit. The parameter is not configurable since it simply
toggles the bit from 0 to 1. (To reset the bit to 0, use the Diag
Clear Tag Status command described below.)
