DVP-ES2/EX2/EC5/SS2/SA2/SX2/SE&TP Operation Manual - Programming

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.

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.
