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.. -
Page 6: V79 Pdi-1 Module
V79 PDI-1 MODULE The main features of the V79 PDI-1 module are sixteen microprocessor-controlled input channels that can be connected with individual ground returns, or a common single-point ground. The input channels provide a flexible, reliable method to detect and report the change-in-state of a circuit. The change can be from infinite resistance (open) to continuity (closed), and vice versa. -

CHANNEL Table 1 Dip switch SW1 1-8 provides filtering control for channels 1-8 while SW2 1-8 controls channels 9-16. Refer to Table 1 to determine which switch corresponds to a particular channel. A port is configured for AC operation by positioning the corresponding switch to ON position. -
Page 11: Operation
(Section 4.4), and presentation (Section 4.5). GENERAL The V79 PDI-1 and V80 PDI-2 modules are used in applications requiring notification of device status (e.g., burglar and fire alarms, event counters/timers, process control, etc.). The PDI-1 module has 16 channel switch inputs providing a reliable method to detect and report a state change from high resistance (open) to continuity (closed) or vice versa. -
Page 12: User-Programmable Features
USER-PROGRAMMABLE FEATURES You may program the Sampling Setup, Reporting Setup, and Dynamic Configuration on the PDI which are discussed in Section 4.2.1 through Section 4.2.3 respectively. 4.2.1 SAMPLING SETUP Sampling Setup allows you to program the Debounce Delay and Latch Polarity for the input channels. -
Page 13: Report Start Time
4.2.2.2 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. -
Page 14: Terminating Character(S)
4.2.2.6 TERMINATING CHARACTER(S) The Terminating Character(s) is added at the end of an event sample to match the requirements of the host terminal or application software. The Terminating Character(s) consists of one or two hexadecimal characters. Terminating Characters are 0D Hex ( Carriage Return ) followed by 0A Hex ( Line Feed ). - Page 15 Once the PDI is selected, it will go into Command Mode and allow you to send data commands. The PDI data commands begin with two capital letters designating the specific command and are terminated with a Carriage Return. Most data commands also require a number between the command letters and Carriage Return.

Page 16: Clear Event Buffer Command
4.3.1 CLEAR EVENT BUFFER COMMAND The Clear Event Buffer (CB) command is used to clear all stored event samples from the buffer of the selected channel(s). The Clear Event Buffer command has the following format: CB n<cr> where c = Channel# (1 to 16 or 0 for all). 4.3.2 CLEAR EVENT COUNTER COMMAND The Clear Event Counter (CC) command is used to reset the event counter for one or more channels to zero without reading the value of the event counter. -
Page 17: Report All Buffered Events Command
4.3.4 REPORT ALL BUFFERED EVENTS COMMAND The Report All Buffered Events (RA) command instructs the PDI to report all event samples currently stored in the buffer of the selected channel(s). The Report All Buffered Events command has the following format: RA n<cr>... -
Page 18: Report Event Latch Data Command
4.3.7 REPORT EVENT LATCH DATA COMMAND The Report Event Latch Data (RL) command instructs the PDI to report the active state of the initial event and the time the initial event occurred (if time tagging is enabled). This command does not reset the latch buffer. The Report Event Latch Data has the following format: RL c <cr>... -

(HI to LO) as determined by the Latch Polarity (see Section 5.1.3). On the PDI-1 switch closure module, an input is considered to be at a "HI" or "1" state when it is closed (continuity) and a "LO" or "0" state when it is open (infinite resistance). - Page 20 Therefore, if a PDI module is connected to a relay or switch that has "dirty" contacts, the total measurement will be less than the actual activation duration of the circuit by the amount of time spent settling.

Page 21: Event Sample Presentation
EVENT SAMPLE PRESENTATION Event Sample presentation varies slightly in format depending on module configuration. Entries such as, time tag, data format, number of active channels, etc. all change how event samples appear to a host-controller. However, all event samples are presented in the same basic order of fields as follows: UU:MM,CC 1 0 MM/DD/YY HH:MM:SS where,... - Page 22 The following examples show the messages received using data commands where the PDI is installed in Unit 1 Module 15 with time tagging enabled. If you select the module and issue the RD1<cr> 1), the module will respond with a single message showing the Event Duration for Channel 1 similar to the following: 1:15,1 1320 11/18/93 09:12:22 where...
-
Page 23: Configuration
If you issue the RL1<cr> command (Report Event Latch Data for Channel 1), the module will respond with a message showing the state of the input that started the initial event. This will be "1" (closed) for LO to HI Latch Polarity or "0" (open) for HI to LO Latch Polarity if using the PDI-1. - Page 24 For example, if the PDI is installed in a non-cascaded unit as Module 2 and you are using the default port select code ($BT), send into configuration mode. No characters should be typed between $BT2<cr> and $CONFIG<cr>. If this happens, the entire configuration sequence will be discarded and you will have to send the configuration sequence again.

Page 27: Reporting Setup
Type the desired debounce delay time followed by <ENTER>. 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. If you type "2" from the "Sampling Setup" menu shown on the previous page (Latch Polarity), the PDI will respond with the following: SET LATCH POLARITY Latch Polarity...HI TO LO... -
Page 28: Reporting Method
If you respond to one of the above selections with 1 to 6, a sub-menu will be presented for that item. After making any necessary changes under sub-menus 1 to 6, you be returned to the Reporting Setup menu. The "Exit" selection will return you to the Configuration Main Menu. -
Page 29: Report Start Time
When Schedule Reporting Method is selected, the PDI will begin reporting event samples as events occur at the programmed Report Start Time (see Section 5.1.4.2). The Report Start Time is programmable up to 24 hours in advance of the current (time-of-day) clock time. Event samples are stored in the buffer until the Report Start Time is reached at which time all buffered event samples are reported to the host module. -
Page 30: Report Interval
IMPORTANT: The Current Date and Time is not updated during data entry. You must consider any delays from the time you enter the Report Start Time until you exit the Configuration Main Menu. Be sure to set the Report Start Time far enough ahead of the current time to complete all configurations and exit configuration mode. -
Page 31: Host Address
5.1.4.4 HOST ADDRESS By responding to the Enter Selection: message at the end of the Reporting Setup Menu on page 23 with "4" (Host Address), you may program the address of the designated host module. The designated host module is where event samples are sent when using Immediate or Schedule Reporting Method. -
Page 32: Terminating Character(S)
With time tag enabled, a MM/DD/YY HH/MM/SS entry is appended to all samples, where MM is the month, DD is the day, YY is the year, HH is the hour, MM is the minute, and SS is the second according to the base unit's time-of-day clock. 5.1.4.6 TERMINATING CHARACTER(S) By responding to the Enter Selection: message at the end of the Reporting Setup Menu on page 26 with "7"... -

Page 34: Dynamic Configuration Procedure And Commands
DYNAMIC CONFIGURATION PROCEDURE AND COMMANDS PDI-1 or PDI-2 dynamic configuration commands are issued through a host module. Some configuration commands apply to all types of DAC modules, while others apply to specific modules. The PDI will recognize dynamic configuration commands only when Dynamic Configuration is enabled (see Section 5.1.5). Use the following procedure to send dynamic configuration commands to the PDI from a host module: Select the PDI from the host module by sending a select sequence which... -
Page 35: Debounce Delay Command

Each command should be terminated with a Carriage Return. 5.2.1 DEBOUNCE DELAY COMMAND The Debounce Delay (DB) command programs the PDI Debounce Delay time (see Section 4.2.2 and Section 5.1.3). The Debounce Delay command has the following format: DB n <cr>... -
