DIO Counter Type:
This parameter will have the following options:
1. Up Counter
2. Down Counter
This parameter defines the behavior of cycle count parameter of the digital IO as an up counter or
down counter for the corresponding channel. This parameter contains the following two values.
Up counter (0): The cycle count associated with digital IO increments by one for every cycle of
digital IO. The cycle count continues to increment beyond the configured cycle limit value (up to
max limit of 20,000,000) in case cycle count type is configured as up counter. The cycle count stops
incrementing after it reaches the max limits of 20,000,000.
Down counter (1): The cycle count associated with digital IO decrements by one for every cycle of
digital IO. The cycle count does not decrement beyond zero after the respective IO is operated
more than the configured maximum cycles in case the cycle type is configured as down counter.
The transition of digital IO from OFF to ON to OFF is counted as one cycle.
•
DI Inversion: This parameter will have the following options:
1. OFF
2. ON
This parameter enables or disables the inversion on digital input for each corresponding input
channel. If this parameter is enabled, then the inverted status of the respective input is
communicated to PLC. The invert functionality is not applicable to LED indication on the PCH
Portal. This parameter has two values:
ON (1): Enables the inversion mode in the PCH Portal.
OFF (0): Disables the inversion mode in the PCH Portal.
•
DI De-bounce time:
This parameter defines the de-bounce time for each corresponding channel to avoid jitter in the
input signal. This parameter applies for both ON to OFF and OFF to ON transition. If the de-bounce
time configured is 0, then it disables the de-bounce logic.
The valid range of this parameter 0 to 120 msec in decimal.
•
DO Fault Mode:
This parameter will have the following options:
1. OFF
2. Last Good
Fault Mode (FM): This field is presently not used and the same is removed from the data map in
the next release.
