Inverted Instrument Status. This is an inverted (bitwise) version of the preceding parameter and is provided so that scrolling
messages can be triggered when a condition is not active. Bit mappings are as the “Instrument Status”, Modbus address 75

HYST.H
Ch1 On/Off Hysteresis in Eng Units
86
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.

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.
