Function of the Digital Input
Select one of the following functions for the digital input:
• Input
• Hardware gate
• Latch Function
• Synchronization
Function of the Digital Outputs
Select one of the following functions for each digital output:
• Output, no switching through comparator
• Activation at a counter status greater than or equal to the comparison value
• Activation at a counter status less than or equal to the comparison value
• Pulse on reaching the comparison value
• Switching at comparison values (DO1 only)
Influencing the Behavior of the Digital Outputs through:
The behavior of the digital outputs can be influenced as follows:
• Hysteresis
• Pulse duration
Changing values during operation
The following values can be changed during operation:
• Load value (LOAD_PREPARE)
• Counter status (LOAD_VAL)
• Comparison value 1 (CMP_VAL1)
• Comparison value 2 (CMP_VAL2)
• Function and behavior of the digital outputs (C_DOPARAM)
