Comparison Instructions Section 5-18
Example The following example shows the comparisons made and the results provided
for TCMP(85). Here, the comparison is made during each cycle when IR
00000 is ON.
5-18-3 BLOCK COMPARE – BCMP(68)
Note BCMP(68) is an expansion instruction for the SRM1. The function code 68 is
the factory setting and can be changed for the SRM1 if desired.
Limitations Each lower limit word in the comparison block must be less than or equal to
the upper limit.
DM 6144 to DM 6655 cannot be used for R.
Description When the execution condition is OFF, BCMP(68) is not executed. When the
execution condition is ON, BCMP(68) compares CD to the ranges defined by
a block consisting of CB, CB+1, CB+2, ..., CB+31. Each range is defined by
two words, the first one providing the lower limit and the second word provid-
ing the upper limit. If CD is found to be within any of these ranges (inclusive of
the upper and lower limits), the corresponding bit in R is set. The comparisons
