Functions of SitrFC43
The functions for this block are listed below.
Configuration data
The configuration data comprises the units, the configuration of the
PV_In
input and the HART
auxiliary variables
SV
,
QV
and
PV
and the limits for messages. After a change is made in the
device, reading of configuration data must be triggered with "Read configuration data" in the
parameter view of the faceplate. If the parameters were read back before a complete download
to the PLC, the configuration does not need to be reloaded from the device.
The message limits of the SitrFC43 are only transferred to the device when the alarm
configuration is synchronized with the device (
Feature
Bit 7 = TRUE).
The SitrFC43 function block has the following configuration data which can be read out of the
FC430 by means of the "Read configuration data" command:
