0 = input open
1 = input voltage < 1 VDC
If SWX4-3 open:
1 = input open
0 = input voltage > 3 VDC
6 User DIN4 Digital If SWX4-4 closed:
0 = input open
1 = input voltage < 1 VDC
If SWX4-4 open:
1 = input open
0 = input voltage > 3 VDC
30 User DOUT1 Digital State of digital output 1
0 = not energized
1 = energized
Start Analog Channels (data values are floating point, precision is user configurable)
62 User Analog Analog Onboard analog input, 10-bit ADC can be configured
for 0-1 VDC, 0-5 VDC, 0-10 VDC, or 0-20 mA
154 Daily Flow
Volume Derived Accumulated flow volume for the day
(flow rate from ADC input)
155 Running
Flow Volume Derived Accumulated flow volume since last volume reset
(flow rate from ADC input)
4.2 Channel Data
All values read from physical IO or from a Modbus slave device are continually updated and tested as defined by
the configuration parameters. For each channel, based on its type (analog or digital), there is a basic set of data
collected. For purposes of discussion, the term “not normal” is used to indicate an analog value that has violated a
limit threshold or a digital value that does not match its configured ‘normal’ state.
Basic Data Set –
For the analog channel:
•
Current value
•
Max/min values (daily and trip)
