You have the choice of programming the PDI via verbose (menu-driven) or non-
verbose (dynamic) configuration mode. When using verbose mode, a series of menus
will prompt you to enter the desired parameters. Non-verbose mode allows you to
program the PDI by downloading configuration commands.
USER-PROGRAMMABLE FEATURES
You may program the Sampling Setup, Reporting Setup, and Dynamic Configuration
on the PDI.
SAMPLING SETUP
Sampling Setup allows you to program the Debounce Delay and Latch Polarity for
the input channels. The Debounce Delay is used to guard against erroneous events.
An event will not be valid unless the input channel has remained at a changed state
for the debounce duration. The debounce delay may be programmed from 0 (for no
debounce) to 65535 milliseconds. The Latch Polarity is used to latch individual
inputs based on a positive going (LO to HI) or negative going (HI to LO) input. The
latch information is retained in memory until recalled by the user. The default
Debounce Delay time is 100 milliseconds and the default Latch Polarity is a HI to LO
transition.
REPORTING SETUP
Reporting Setup allows you to program how the PDI reports event samples to the host
module. The items you may program in the Reporting Setup include Reporting
Method, Report Start Time, Report Interval, Set Host Address, Data Format, Time
Tag, and Terminating Character(s).
REPORTING METHOD
Reporting Method is the manner in which event samples are sent to the designated
host module. The PDI provides three Reporting Methods: Command (upon request
via data commands), Immediate (upon exiting configuration), and Schedule (where
reporting begins at a specified time). The default Reporting Method is Command.
REPORT START TIME
Report Start Time is the time reporting begins when Schedule Reporting Method is
selected. The start of reporting may be delayed up to 24 hours from the current time
recorded by the M Series time-of-day clock and reporting will occur in cyclic periods
as determined by the Report Interval. The default Report Start Time is 00:00.
