After an edge reversal at input
byByte8_Control from Low to High, the specified values are
transmitted to the counter module.
Selection in control byte
00000000
00110011
byByte9_Status
This input may be used to store the last count value in the module, or to start counting at 0 on restart.
·
1 = Count value is stored
·
2 = Count value is cleared on restart (default)
·
The written data are supplied at the following outputs:
– abyPDO_Data1ToIO
– abyPDO_Data2ToIO
Note!
The counter module takes up two Rx and two Tx PDOs.

Byte Specify start or comparison values to the counter module.
Example:
The module was parameterised as 2 x 32 bit counter. If the counter is to start at a
count value 77, this value must be available at input byByte2_Counter01.
byByte8_Control Byte Accept specified values at the following inputs after Low to High edge reversal.
