Parameter
Mnemonic Parameter Name Modbus
Address
(Decimal)
PV.IN PV (Temperature) Input Value (see
also Modbus address 203 which
allows writes over Modbus to this
variable). 1
RNG.LO Input Range Low Limit 11
RNG.HI Input Range High Limit 12
A1.--- Alarm 1 Threshold 13
A2.--- Alarm 2 Threshold 14
Cal offset 4 26
LOC.t Local Trim – added to the remote
setpoint to compensate for local
temperature variations in a control
zone. 27
A1.HYS Alarm 1 Hysteresis 47

Cal point 3 67
A2.HYS Alarm 2 Hysteresis 68

StAt
Instrument Status. This is a bitmap:
B0 – Alarm 1 Status
B1 – Alarm 2 Status
B2 – Alarm 3 Status
B3 – Alarm 4 Status
B5 – Sensor Break Status
B10 – PV Overrange (by > 5% of
span)
B12 – New Alarm Status
In each case, a setting of 1 signifies
‘Active’, 0 signifies ‘Inactive’. 75
A3.--- Alarm 3 Threshold 81
A4.--- Alarm 4 Threshold 82
Di.IP
Digital Inputs Status. This is a
bitmap:
B0 – Logic input 1A
B1 – Logic input LA
B2 – Logic input LB
B7 – Power has failed since last
alarm acknowledge
A value of 1 signifies the input is
closed, otherwise it is zero. Values
are undefined if options are not
fitted or not configured as inputs. 87
FILT.T Input Filter Time 101

6 – PV only
7 – PV and Alarm 1 setpoint read

- Instrument version number. Should
be read as a hexadecimal number,
for example a value of 0111 hex is
instrument V1.11 107

0 – Operating mode - all algorithms
and I/O are active
1 – Standby - control outputs are off
2 – Config Mode - all outputs are
inactive 199
COLOR Colour change

Green normal/Red on alarm – 200
MV.IN Input value in millivolts 202
PV.CM
Comms PV Value. This may be
used to write to the Process
Variable (temperature) parameter
over Modbus when a linearisation
type of ‘Comms’ is selected,
allowing the instrument to control to
externally derived values.
If sensor break is turned on, it is
necessary to write to this variable
once every 5 seconds. Otherwise a
sensor break alarm will be triggered
as a failsafe. If this is not required,
turn sensor break off. 203
