hysteresis value is common to all four analogue inputs, faults and set points. The current
hysteresis value can be displayed by simply entering the command name as shown in the
example below:
TX4A::>HYST
Hysteresis level 0.10mA
TX4A::>_
If the command name is entered with additional attributes the hysteresis level can be
configured to any valid level. An example of configuring the hysteresis level is shown
below:
TX4A::>HYST SET 0.21
Setting Changed
Hysteresis level 0.21mA
TX4A::>_
The range of the hysteresis is from 0.01mA to 1.00mA.
6.15 ANALOGUE SELECT COMMAND
This command is used to display and configure the analogue transmission protocol for
each of the analogue inputs. Each analogue input can be configured to either Analink or
Fastlink. The current selected transmission protocols can be displayed by simply entering
the command name as shown in the example below:
TX4A::>ANASEL
Chan[1] = Analink
Chan[2] = Analink
Chan[3] = Analink
Chan[4] = Analink
TX4A::>_
If the command name is entered with additional attributes the analogue transmission
protocol can be configured to Fastlink or Analink for each analogue input. An example of
configuring input 1 is shown below:
TX4A::>ANASEL SET 1 FASTLINK
Setting Changed
Chan[1] = Fastlink (Marker Error)
Chan[2] = Analink
Chan[3] = Analink
Chan[4] = Analink
TX4A::>_
The ‘marker error’ has been displayed because analogue input one has been configured
to Fastlink but a valid Fastlink marker channel address has not been specified. See the
Fastlink marker command (FSTMRK) for details on assigning a valid marker address.
