SUPERVISORY MESSAGE BLOCK

8.9 SUPERVISORY MESSAGE BLOCK (SM)
The supervisory message block is used to send a single, logic or manually initiated, message
over the ICN, or internally (within the MODCELL unit) to an addressable attribute. This block
can be used to send any one of the following types of messages to the specified instrument
types:
Message Type Instrument Types
Read All instruments
Read with Quality MODCELL only
Write All instruments
Set MODCELL only (within instrument)
Tune Any instrument except MODCELL (CTRL, REC, SLU, or
MATH)
Configure Any instrument except MODCELL
Demand Configure Any instrument except MODCELL
The block can be configured to wait a specified maximum time for the transaction to complete.
A separate supervisory message block must be configured for each message.
Block outputs are the result, message active and failure flags, the failure count, a message
code indicating success or type of failure, and quality information. A functional block diagram
of a supervisory message block is shown in Figure 8-42. The general and message displays
used to configure the supervisory message block are shown in Figures 8-43 and 8-44.
