DVP-ES2/EX2/EC5/SS2/SA2/SX2/SE&TP Operation Manual - Programming
-136
instruction uses C245 as high speed counter (group A) at the same time, PLC takes C243
as the source counter automatically and no syntax check error will be detected.
 Designers have to specify the comparison value of a hardware comparator before they
enable a comparison instruction. If the comparison value of a hardware comparator has to
be changed after a comparison instruction is enabled, it is suggested that users should
disable the comparison instruction first. After the users specify a new comparison value, the
users can enable the comparison instruction again.
 If users want to change the value of a hardware comparator without disabling the
high-speed comparison instruction which is being used, they have to check whether the
model used support this operation. The models which support this operation are listed
below.
Model name ES2/EX2 EC5 SS2 SA2 SX2 SE
Version V3.20 V1.00 V3.00 V2.60 V2.40 V1.00
Note: If the comparative value changes, it will not be stored in the hardware comparator
until the instruction is scanned.
