Ptxx – Digital Input, Timestamp View

Use Ptxx – Digital Input, Timestamp to view or configure the points for the device.
Ptxx – Digital Input, Timestamp View Example
The Ptxx – Digital Input, Timestamp view includes these parameters:
Parameter
Description
Power Source
Defines the power source for the point.
  • Ptxx – Power is supplied to the sensor from point xx of this module, which is configured to function as a power supply.
    If a short circuit is detected on the Power Supply point, the fault is rolled-up to the Digital Input point.
  • External – Power is supplied to the sensor from an external power supply.
  • SSV – Power is supplied to the sensor from the SSV terminal of this module.
    If an SSV short circuit is detected, the fault is rolled-up to the Digital Input point.
Input Filters
Off → On Filter Time
Defines how long an Off to On input transition must remain in the On state before the device considers the transition valid.
Input Filters
On → Off Filter Time
Defines how long an On to Off input transition must remain in the Off state before the device considers the transition valid.
Enable Timestamp Latching
Determines whether timestamps are latched.
  • When enabled, the device timestamps are not overwritten until acknowledged.
  • When disabled, the device timestamps may be overwritten.
Capture Timestamp for Off → On Input Transition
Determines whether a timestamp is recorded for the Off to On input transition.
Capture Timestamp for On → Off Input Transition
Determines whether a timestamp is recorded for the On to Off input transition.
Enable Chatter Detection
Sets chatter detection. When enabled, chatter from a device that is connected to one of its inputs (for example, rapid transitions from a failed contact) is ignored.
Chatter can cause the device to timestamp invalid input transitions. Typically, chattering signals cause inputs to transition falsely many times in a relatively short period of time.
Chatter Count
Determines the number of acceptable input transitions that can occur in a given time period before considering the input to be chatter.
Valid values are 2…127.
Chatter Time
Determines the amount of time, from 1…10,000 milliseconds, within which the number of input transitions are counted.
Diagnostics
Opens the Diagnostics dialog, which contains diagnostic information.
