15 4.3.10 REPORT A SINGLE BUFFERED EVENT COMMAND The Report A Single Buffered Event (RS) command instructs the PDI to report the first event sample stored in the buffer of the selected channel(s). The Report A Single Buffer Sample command has the following format: RS c <cr> where c = Channel# (1 to 16 or 0 for all). 4.4 EVENT SAMPLE REPORTING[...]

16 The PDI module can observe, record, and report when an event happened, how long the event lasted, and how many events occurred for each individual channel. The initial occurrence of an event will set the event latch bit and store the associated time in the latch buffer . You may read the state of the initial event and the time it was recorded (i[...]

17 4.5 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 or[...]

18 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> command (Report Event Duration for Channel 1), the module will respond with a single message showing the Event Duration for Channel 1 similar to the f[...]

19 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. This will be "1" (v[...]

20 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 $BT2<cr>$CONFIG<cr> to enter into configuration mode.
