Up Counter
To set the counter, proceed as follows:
1.
First set the counter to the decimal value 100 (hexadecimal 0x64) via "Set
counter," by setting the counter value in the output data:
Data Bytes
Output Data
D3
D2
D1
D0
Value
0x00
0x00
0x00
0x64
2.
Report the counter value as valid in the control byte with bit 5 (set counter),
so that it is applied as the output value:
Control Byte
Output Bit
B7
W 6
W 5
W 4 W 3 W 2 W 1
B0

The set counter value then appears in the input data with the following data bytes
D0 to D3:

5.
For counting upward, wait for the first and additional count pulses:
There must be power at the input “U/D.”
First, make sure the counting is enabled with +24 V at the input “U/D.”
