1 GENERAL

BayTech's PDI modules are designed for use with the M16 and M8 (DAC) Data Acquisition Controllers. Both modules are used to detect events where an event is defined as a change-in-state of an input and return to the original state. The V79 PDI-1 module is used for the detection of switch closure in applications requiring notification of device status such as burglar alarms, fire alarms, event counters and timers, process control, etc.. The V80 PDI-2 is used for the detection of optically isolated voltage inputs in applications requiring industrial control of motors, process monitoring, limit switch status, and the monitoring of relay status.

All events detected by either module are recorded as an event sample and sent to a host computer/controller connected to a V71 host module. The current status of input channels may be provided to the host computer/controller upon request. Event samples or input channel status may be provided with a "time stamp" or "Time Tag" which is available through the use of a "time-of-day" clock located in the M16/M8 base unit. A time tag includes the month, day, year, hour, minute and second the event occurred or the input channel status was taken.

Event status is supplied to the host computer/controller in one of the following modes:

1)Upon user request (COMMAND).

2)At a specific date/time (SCHEDULE).

3)Real time reporting of events (i.e., as events occur IMMEDIATE).
