To configure the Diag Fault Level parameter, click the button
to open a standard Build Argument dialog.
o 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.)
B.4.3 Diag Clear Tag Status
This command can be selected from the Diagnostics commands list.

Destination Tag – The Input, Output, or Memory tag on which the
diagnostic item will be cleared.
To configure the Destination Tag parameter, click the button to open a
standard Select Tag dialog.
Diag Item – The type of diagnostic item that will be cleared by the
command. Available items include Diag Fault Bit, Diag Fault Level, Diag
Status Code, and Error Status Bit (input and Output tags only).
