Name:
ConfigOutput02
This register can be used to set the range of the current signal. This is determined by how they are configured.
The following input signals can be set:
•
0 to 20 mA current signal
•
4 to 20 mA current signal
Data type Value
USINT See bit structure.
Bit structure:
Bit Description Value Information
0 0 to 20 mA current signal 0 Channel 1: Current measurement range
1 4 to 20 mA current signal
... ...
0 0 to 20 mA current signal 7 Channel 8: Current measurement range
1 4 to 20 mA current signal
4.3.13.8.8 Lower limit value
Name:
ConfigOutput03
This register can be used to configure the lower limit for analog values. If the analog value goes below the limit
value, it is frozen at this value and the corresponding error status bit is set.
Data type Value
INT -32,768 to 32,767
Information:
•
When configured as 0 to 20 mA, this value should be set to 0.
•
When configured as 4 to 20 mA, this value can be set to -8192 (corresponds to 0 mA) in order
to display values <4 mA.
Keep in mind that this setting applies to all channels!
4.3.13.8.9 Upper limit value
Name:
ConfigOutput04
This register can be used to configure the upper limit for analog values. If the analog value goes above the limit
value, it is frozen at this value and the corresponding error status bit is set.
Data type Value
INT -32,768 to 32,767
Information:
The default value of 32767 corresponds to the maximum default value at 20 mA.
Keep in mind that this setting applies to all channels!
