Version A
For the digital channels:
•
Current value
•
Previous value
•
Count of transitions to not normal (counts)
•

There are a few channels that can be configured for special functions. All the physical digital input channels can
accept pulse inputs (e.g., from a flow meter) and the physical analog input can be used to totalize volume when
the input is flow rate. These channels have an extended data set.
Extended Data Set –
For the analog channel:
•
Daily total volume (available on separate channel, 154)
•
Continuous running total volume (available on separate channel, 155)
For the digital channels:
•
Flow rate
•
Daily total volume
•
Continuous running total volume
The Messenger W also maintains a set of daily data.
The daily data set is a separate set of current and max/min values that span the 24 hour period from midnight to
midnight, UTC time. At midnight, an end of day report is generated from this data.
Because Modbus channel data is polled, Modbus digital channels do not maintain count or duration values.
