11.15.2 Long/Short Value
The first byte of word address +1 contains a number that indicates the length of the
fault-specific data in the fault entry. These possible values are:
PLC fault table
00 = 8 bytes (short)
01 = 24 bytes (long)
I/O fault table
02 = 5 bytes (short)
03 = 21 bytes (long)
11.15.3 Example of SVCREQ 15
When inputs %I0250 and %I0251 are both on, the first Move function places a zero (read
PLC fault table) into the parameter block for SVCREQ 15. When input %I0250 is on and
input %I0251 is off, the Move instruction instead places a one (read I/O fault table) in the
SVCREQ parameter block. The parameter block is located at location %R0600.
