Channel shadowing
Channel shadowing
With reference to the "Standard connections: Channel mapping" section of this document, Cello 4S allows up to eight
channels to be monitord and recorded with each physical input being allocated, in the configuration file, to one of those
channels. However in addition any physical input can be copied, or "shadowed", to more than one channel with each
channel then being treated differently.
For example:
Forward and reverse signals ('FR' mode):
Flow and direction ('State') signals ('FD' mode):
Transient pressure recording:
Pressure, P1
Ch. 1: 15 minute logging rate, high resolution
Flow, GPi2
Ch. 2: Count, 5 minute logging rate
Ch. 3: Event, high resolution
Ch. 4: 1 minute logging rate, low resolution
Forward, GPi2
Ch. 2: Count, F only
Reverse, GPi3
Ch. 3: Count (FR), F - R
Ch. 4: Count, R only
Flow, GPi2
Ch. 2: Count, F only
Direction, GPi3
Ch. 3: Count (FD), +F and -F
Ch. 4: State
Pressure, P1
Ch. 1: 15 minute logging rate, high resolution
Flow, GPi2
Ch. 2: Count, 5 minute logging rate
Ch. 3: Media temperature
Ch. 4:
Reserved for Pressure input P2
Ch. 5:Transient events
(Note - transient recording
is fixed on this channel)
