Switch “T” on, switch “C” off
(see Channel 2 & 3 configuration above)
Definition for range, over-range/under-range and status flag:
Temperature inputs:
Model
min./max. Status flag
Value Range
Pt 1000 (-50…400 °C)
-500 / 4000
Limits -500...4000
Ni 1000 (-50…210 °C)
-500 / 2100
Limits -500...2100
Ni 1000 L&S (-30…140 °C)
-500 / 1400
Limits -300...1400
Each time the min./max. values are reached, the min./max. status flag is set.
Resistance, voltage and current inputs:
The overall value range is defined by the range type:
Model
min./max. Status flag
Range of the calculated
values
Resistance 0…2500 Ω
0…25000 Min. Flag not set
Limit exceeded
25500 (25000+2%)
Voltage input (-10...+10V)
Xx / yy
102% of the defined range
Current input (-20...+20mA)
Xx / yy
102%
Each time the min./max. values are reached, the min./max. status flag is set.

The status flag remains set until the status has been read. With media mapping
the status flag is read at the end of each COB. This means that the status flag
is reset at the end of each COB.
With direct access, the status flag is reset as soon as the user program reads
the status flag.
