The Sixth to Ninth byte determine the alarm mode
configuration and the connection configuration for
PT100 and the cold junction configuration for
THERMO modules for each channel respectively
Alarm mode configuration is configured with the fol-
lowing values. By default the alarm modes are dis-
abled. Each channel has 2 alarms. Each alarm one
threshold value is associated. The alarm (which is
one bit in the diagnostic status data of the module) is
active, if the input value of the associated channel is
above/below (dependent if it is a high or low alarm)
the threshold value. The configured hysteresis value
is taken into account for the alarm recognition. The
hysteresis value is that distance that must be
reached, before the alarm is cleared again.
Bit 3 to 2
00 = alarm 1 off
01 = low alarm
10 = high alarm
Bit 4 to 5
00 = alarm 2 off
01 = low alarm
10 =high alarm
The connection configuration for PT100 modules
can be configured with the lower two bits of these
configuration bytes for each channel separately. Fol-
lowing table shows the values:
Bit 1 to 0
00 = 4 wire connection
01 = 3 wire connection
10 = 2 wire connection
For the THERMO module, these bits determine the
cold junction compensation mode.
Bit 1 to 0
00 = external PT1000
01 = manual compensation with
value from first connector
10 = internal compensation (which
has an error of typically 2%)
