Endless Counting

Definition
In this mode, the 1Count24V/100kHz counts continuously starting from the load value:
• If the 1Count24V/100kHz reaches the high counting limit when counting up, and another
• If the 1Count24V/100kHz reaches the low counting limit when counting down, and
• The high counting limit is set to +2147483647 (2
• The low counting limit is set to -2147483648 (-2

Function of the Digital Input
For the "Function DI" parameter, select one of the following functions for the digital input:
• Input
• HW gate
• Latch function
• Synchronization
Function of the Digital Outputs
For the "Function DO1" and "Function DO2" parameters, select one of the following
functions for each digital output:
• Output, no switching by comparator
• Switch on at count greater than or equal to the comparison value
• Switch on at count less than or equal to the comparison value
• Pulse on reaching the comparison value
• Switch at comparison values (DO1 only)

count pulse then comes, it will jump to the low counting limit and continue counting from
there without losing a pulse.
another count pulse then comes, it will jump to the high counting limit and continue
counting from there without losing a pulse.
