NOTIFICATION/REQUEST MESSAGE BLOCK
8-66
8.8.1 Notification/Request Message Block Operation
The Notification/Request Message block is a loop function block that sends and receives
messages based upon being triggered by a “send” source input transition from 0 to 1 or a
send command being issued via operator write.
On a warm start, the previous state values for the send input and remote acknowledge input
are maintained. On a cold or frozen restart, the previous send input and remote acknowledge
values (saved as part of the block) are set to FALSE.
8.8.2 Notification/Request Message Block Parameters
The mnemonics, valid values, and data types for all fields that may be selected for display
and/or be used in making softwiring connections are listed in Table 8-7. The following further
defines the Notification/Request Message block configuration parameters.
Block Type
NM
This is the Notification/Request Message block type.
Occurrence
1 to 4096
There may be up to 4096 ‘instances’ allowed of the NM block type.
