V78 CRM-1 COMMAND SUMMARY

Command Description

history (change of state).

DRr<cr> (r=Relay# 1 to 8,

0=all*)

SAr<cr> (r=Relay# 1 to 8,

0=all*)

Sample. Read and report the current status of the

selected relay(s).

* Multiple relays are selected using 4 formats. Examples: SA1,2,3,4,5,6,7,8<cr>, SA1-

8<cr>,

SA0<cr>, SA1,2,4-8<cr>

For example, suppose the CRM-1 is installed in Unit 1

Module 15 with time tagging enabled. Once you select

the CRM-1 and issue the RS1,2<cr> command, the

module responds with a single message from Relay #1

and Relay #2 similar to the following:

1:15,1 1 11/18/93 09:12:22<cr><lf>

1:15,2 1 11/18/93 09:12:22<cr><lf>

where 1:15,1 represents Unit 1/Module 15/Channel 1,

1:15,2 represents Unit 1/Module 15/Channel 2, 1

indicates that Relay #1 and Relay #2 are energized,

11/18/93 09:12:22 is the time tag which is the same

for both relays in this example, and <cr><lf> is the

Carriage Return and Line Feed terminating characters.
