Configuration and Programming 4-7
INT: Interrupt Enable
(Word 1, Bit 10)
In Class 4, when this bit is set (1), the module generates an I/O
interrupt to the SLC processor whenever one of the eight outputs
changes state. When this bit is reset (0), the module will not generate
an interrupt.
RVF: Rate Value Format
(Word 1, Bit 09)
In Class 4, the module transmits the rate value in a two-word integer
format when this bit is reset (0). The module transmits the rate value
in single-precision floating-point format when this bit is set (1).
PRA: Program Range Allocation
(Word 1, Bit 08)
When this bit is set (1), the module programs the range allocation to
the values in words 2, 3, and 4.
IMPORTANT
Interrupt mode is not available in Class 1. Setting this
bit while using Class 1 causes a programming error.
IMPORTANT
An I/O interrupt must be defined if the INT bit is set.
The I/O interrupt subroutine number is defined in the
advanced configuration window of the program’s I/O
configuration. See the SLC 500 Instruction Set
Reference Manual, publication number 1747-RM001,
for more information on I/O interrupts.
IMPORTANT
This bit is not used in Class 1. Setting this bit while
using Class 1 causes a programming error.
