Timer and Counter Instructions

Refresh Methods for Timer/Counter PV
Overview
There are two PV refresh methods for instructions related to timer/counters, "BCD" and "BINARY".
Method
BCD Sets the timer set value in BCD.
Binary Sets the timer set value in BINARY.
The PLC Setup for all of the timer/counter-related instructions. The refresh method is valid also when
setting an SV indirectly (i.e., using the contents of memory word). (That is, the contents of the
addressed word is taken as either BCD or binary data according to the refresh method that is set.)

Setting method for PV refresh
BCD and binary PV refreshing can both be used in the same project. The setting of the PV refresh
method in the PLC Setup will be ignored.
