Applicable Program Areas
Operands
N1: First Number in Range
N1 must be a timer number between T0000 and T4095 or a counter number between C0000 and
C4095.
N2: Last Number in Range
N2 must be a timer number between T0000 and T4095 or a counter number between C0000 and
C4095
Note N1 and N2 must be in the same data area, i.e., N1 and N2 must be timer numbers or counter numbers.
z Operand Specifications
Flags
Function
CNR(545)/CNRX(547) resets the Completion Flags of all timers or counters from N1 to N2. At the same
time, the PVs will all be set to the maximum value (9999 for BCD and FFFF for binary). (The PV will be
set to the SV the next time that the timer or counter instruction is executed.)
