5.1.5 Hold module
With the help of the hold module, it can be determined how to proceed in the event of invalid measurement
values. It ensures the last valid measurement value is retained until a new valid measurement value is
available or passes the error on after a certain number of invalid measurements. The hold module is only
available for the universal inputs in the "Freq", "PWM", "Voltage", "PT1000", "KTY81110", "KTY81210",
"NI1000" and "TK5000" channel modes.
The following table specifies the relevant parameters for the module:

5.1.6 Alarm/trigger module
This module monitors the alarm limits and trigger levels and creates an entry in the alarm list if necessary. The
global triggers are also set (see "Alarm flags" on page 31 or "Trigger flags" on page 31). The alarm/trigger
module is available for inputs (universal inputs and internal channels).
All of the parameters of the "Alarms" and "Trigger" tabs of the "Measurement channels" (see "Measurement
channels" on page 65) and "Internal channels" (see "Internal channels" on page 84) configuration sections
are relevant to this module. Additionally, the parameters in the following tables are also relevant:
Configuration section Parameter Explanation
Alarm settings On alarm A The alarm is recorded in the alarm list.
On warning A The warning is recorded in the alarm list.
On fault alarm A The fault alarm is recorded in the alarm list.
On fault warning A The fault warning is recorded in the alarm
list.
