Data Tables
In the SLC 500 data tables, table N111 is the destination table for the
Read message and N211 is the source for the Write message.
Table N211 contains the following values for setting the date and time
in a power monitor with a password of 0 to January 1, 2003 at 12:00
midnight.
Table N211
The Read Clock from PM3K and Set Clock from SLC bits are used to
initiate the messages, and are reset when the message instruction
either completes successfully or an error occurs. In your application
code, if the message rungs are controlled programmatically, be sure
that only one message is enabled at a time.
