Change-Of-State; Block Read Mappings - Weidmuller WI-GTWY-9 User Manual

WI-GTWY-9-xxx Wireless Gateway V1.18

4.5.5 Change-of-State

If a value in the block changes by more than the sensitivity amount, then the block message will
be sent (this can only occur for Write mappings). The sensitivity values are set under the
"Sensitivity" option as per section 4.6.
A delay time can be entered to reduce the number of change triggers in active systems. For
example, if 20 seconds is selected in the "Delay" window, then the change message will be sent
20 seconds after the change-of-state occurs - if other changes occur during the 20 second period,
all of these changes are sent in the one message.
The delay time can be set from 0 – 254 seconds.
If you do not wish change messages to occur, select the "Disable" box.

4.5.6 Block Read Mappings

A Read mapping is a request sent to another WI-GTWY-9 to return a block of values. Like the
Block Write mapping it can be triggered by a Real Time clock, Time period or by Host trigger
however the main difference is that the COS Delay is now a Response Timeout as shown below.
