history (change of state).

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

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.
