4.5 Counter Inputs
The following features are supported and remotely configured for each input
individually:
A 16-bit number which is converted to a 32-bit number
with scaling at the iHost system. The current value is
reported to the iHost system during every
communication. When the 16-bit maximum is reached
the counter rolls back to zero and continues.
How long the input must be open (or closed) before a
change of state is confirmed.
Yes = increment the current value by 1 when the input
changes from Closed to Open.
Yes = increment the current value by 1 when the input
changes from Open to Closed.
Yes = create a data log entry for the input with how
many counts the current value increased by for each
30-minute period of the day. The 30-minute data logs
are reported to the iHost system during routine
communications.
In ideal conditions, the processor detects changes of state within 10ms.
4.6 Analogue Inputs
The following features are supported and remotely configured for each input
individually:
An 8-bit value. The Level is reported to iHost during
every communication.
Yes = Take a date/time stamped routine level reading at
the frequency specified (1 min to 24 hours). Date/time
entries are reported during the next iHost
communication.
Dead band Crossing
Logging
Each input has a dead-band percentage. When the level
changes by an amount exceeding the dead-band, the
RTU adds a date/time stamped entry in the analogue
input log.
Threshold Crossing
Logging
Each input has 4 threshold levels providing 5 zones.
When the level crosses a threshold, the RTU adds a
date/time stamped entry in the analogue input log.
Yes = initiate an immediate iHost communication as
soon as a dead-band-crossed event is generated.
Yes = initiate an immediate iHost communication as
soon as a threshold-crossed event is generated.
How long the input must be in a new zone (or dead-
band) before a threshold crossing (or dead-band
crossing) is confirmed.
