Parameters/address space
4.3 Explanation of parameters
Interference frequency suppression
Suppresses the interferences affecting analog input modules that are caused by the
frequency of the AC voltage network used.
The frequency of the AC voltage network is likely to have a negative effect on measured
values particularly with measurement in the low voltage range and on thermocouples. With
this parameter, the user specifies the line frequency that is predominant in the plant.
Measuring range resolution
Parameters for the thermocouple measurement type.
Allows you to increase the resolution to 2 or 3 decimal places for a configurable section of
the measuring range. See section Scalable measuring range (Page 23).
Measuring range center
Determines the temperature over which the scalable measuring range is symmetrically
spanned. The value must be within the nominal range of the underlying measuring range. It
is specified in integers.
Maximum / Minimum
Corresponds to overflow / underflow for the scalable measuring range.
Hardware interrupt enable
Enabling of a hardware interrupt if the high limit 1/2 or the low limit 1/2 is violated.
Low limit 1/2
Specify a threshold which triggers a hardware interrupt when violated.
High limit 1/2
Specify a threshold which triggers a hardware interrupt when violated.
Potential group
Specifies that a BaseUnit with incoming voltage supply is located on this slot (see system
manual ET 200SP distributed I/O system
(http://support.automation.siemens.com/WW/view/en/58649293)).
