Table 5- 6 Configurable "Measuring" parameters
Parameters
1)
Value range
Default
Reconfiguration in RUN
Measuring
• Measurement type
See section Measurement
types and measuring ranges
of the analog on-board I/O
(Page 120)
Voltage
(channels 0 to 3)
Resistance
(channel 4)
Yes
• Measuring range
±10 V
(channels 0 to 3)
600 Ω
(channel 4)
Yes
• Temperature coefficient
Pt: 0.003851
Pt: 0.003916
Pt: 0.003902
Pt: 0.003920
Ni: 0.006180
Ni: 0.006720
0.003851 Yes
• Temperature unit • Kelvin (K)
2)
• Fahrenheit (°F)
• Celsius (°C)
°C Yes
• Interference frequency suppression
400 Hz
60 Hz
50 Hz
10 Hz
50 Hz Yes
3)
• Smoothing
None/weak/medium/strong None Yes
1)
All parameters can be set channel-selective
2)
Kelvin (K) is only possible for the "Standard range" measuring range and not for the "Climatic range" measuring range
3)
The interference frequency suppression must have the same value for all active input channels. This value can only be
changed through reconfiguration in RUN with single channel parameter assignment (data records 0 to 4) if all other in-
put channels are disabled.
Table 5- 7 Configurable "Hardware interrupt" parameters
Parameters
1)
Value range
Default
Reconfiguration in RUN
Hardware interrupts
• Hardware interrupt low limit 1
Yes/No No Yes
• Hardware interrupt high limit 1
Yes/No No Yes
• Hardware interrupt low limit 2
Yes/No No Yes
• Hardware interrupt high limit 2
Yes/No No Yes
1)
All parameters can be set channel-selective
You can find an overview of the limits for the hardware interrupts in the section Structure of a
data record for input channels of the analog on-board I/O (Page 166).
