1Count24V/100kHz
2.6 Count Modes
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)
Influencing the Behavior of the Digital Outputs via:
• Hysteresis
• Pulse duration
Values that Can Be Changed during Operation:
• Load value (LOAD_PREPARE)
• Count (LOAD_VAL)
• Comparison value 1 (CMP_VAL1)
• Comparison value 2 (CMP_VAL2)
• Function and behavior of the digital outputs (C_DOPARAM)
