2.2.10 Interference frequency suppression
The frequency of your AC power system can interfere with the measured value especially
when measuring in low voltage ranges and using thermocouple elements. Enter the line
frequency for your system here (50 Hz or 60 Hz).
The interference frequency suppression parameter applies to all analog electronic modules.
This parameter is also used to specify the integration and conversion time of the various
modules. See the technical data for the analog electronic modules.
2.2.11 Reference junction slot
This parameter allows you to assign a slot (none, 2 to 63) with a channel for measuring the
reference temperature (calculation of the compensation value).
Reference
For information on connecting thermocouples, refer to the
manuals
for the analog electronic
modules.
2.2.12 Reference junction input
This parameter can be used to set the channel (0/1) for measuring the reference
temperature (calculation of the compensation value) for the assigned slot.
Reference
For information on connecting thermocouples, refer to the
manuals
for the
analog electronic
modules
.
2.2.13 Synchronize DP slave with equidistant DP cycle.
This parameter can be used to enable or disable cycle synchronization.
After enabling cycle synchronization the ET 200S I/O are synchronized with the global
control frame of the master (as equidistance cycle).
