Getting Started with Counters
Step 1: Determine Required Counter Function
Counter Functions
1-Stage Counting (
StA6E 1
)
A single count setting value SV is available in 1-Stage Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily or will be maintained ON depending on the Output Mode selected.
2-Stage Counting (
StA6E 2
)
In 2-Stage Counting, count setting value SV1 controls Output 1 and count setting value SV2 controls Output 2.
Outputs will turn ON momentarily or will be maintained ON depending on the output mode selected.
Batch Counting (
bAtCH
)
In Batch Counting, count setting value SV controls Output 2 which will turn ON momentarily or will be main-
tained ON depending on the output mode selected. Count setting value BATCH SV controls Output 1which will
be maintained ON.
Total Counting (
totAL
)
A single count setting value SV is available in Total Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily or will be maintained ON depending on the Output Mode selected.
Dual Counting (
dUAL
)
A single count setting value SV is available in Dual Counting. Both Outputs 1 and 2 operate concurrently and will
turn ON momentarily or will be maintained ON depending on the Output Mode selected.
Step 2: Determine Required Counter Input Mode
Counter Input Modes:
Counting Up (
UP
)*
With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will increment the count
present value PV by 1. Turning ON the input signal at CP2, will prohibit the input signal at CP1 from incrementing
the PV.
With the input signal ON at input CP1, each trailing edge of the input signal at CP2 will increment the count
present value PV by 1. Turning OFF the input signal at CP1, will prohibit the input signal at CP2 from incre-
menting the PV.
Counting Down (
down
)*
With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will decrement the count
present value PV by 1. Turning ON the input signal at CP2, will prohibit the input signal at CP1 from decrementing
the PV.
With the input signal ON at input CP1, each trailing edge of the input signal at CP2 will decrement the count
present value PV by 1. Turning OFF the input signal at CP1, will prohibit the input signal at CP2 from decre-
menting the PV.
Counting Up / Command Counting Down (
Ud A
)*
With the input signal OFF at input CP2, each leading edge of the input signal at CP1 will increment the count
present value PV by 1.
With the input signal ON at input CP2, each leading edge of the input signal at CP1 will decrement the count
present value PV by 1.
Counting Up / Counting Down (
Ud b
)*
Each leading edge of the input signal at CP1 will increment the count present value PV by 1.
Each leading edge of the input signal at CP2 will decrement the count present value PV by 1.
