B-44 SLC Status File
S:27
and
S:28
Status I/O Interrupt Enabled
These two words are bit-mapped to the 30 I/O slots. Bits
S:27/1 through S:28/14 refer to slots 1 through 30. Bits
S:27/0 and S:28/15 are reserved.
The default value of each bit is 1 (set). The enable bit
associated with an interrupting slot must be set when the
interrupt occurs to allow the corresponding ISR to execute.
Otherwise, the ISR does not execute and the associated I/O
slot interrupt pending bit becomes set.
Changes made to these bits using the Data Monitor function
or ladder instructions other than IID or IIE take affect at the
next end of scan.
••••
Dynamic Config These bits may be set/reset by the user program, comms., or
with the IIE or IID instruction. Changes made to these bits
using a programming terminal’s Data Monitor function or
any ladder instruction take effect immediately.

S:29 Dynamic Config User Fault Routine File Number
You enter a program file number (3 to 255) to be used in all
recoverable and non-recoverable major errors. Program the
ladder logic of your fault routine in the file you have
specified. Write a zero value to disable the fault routine.
To provide protection from inadvertent Data Monitor
alteration of your selection, program an unconditional MOV
instruction containing the program file number of your fault
routine to S:29, or program a CLR instruction at S:29 to
prevent fault routine operation.
