Functions of SitrLRPA
The functions for this block are listed below.
Configuration data
The configuration data comprises the units, the configuration of the
PV
inputs, 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 SitrLRPA are only transferred to the device when the alarm
configuration is synchronized with the device (
Feature
Bit7 = TRUE).
The SitrLRPA function block has the following configuration data which can be read out of the
Sitrans LR 250 by means of the "Read configuration data" command:

Limit monitoring
The block monitors the process value 1
PV1
and, if configured, the process value 2
PV2
for
limits. Both values are cyclically integrated into the process image of the controller.
Configuration of the limits is carried out either by means of PDM and imported by reading the
configuration data from the block, or can be carried out on the block independent of the module
(see
Feature
Bit7).
You can monitor the process value 1
PV1
and the process value 2
PV2
for the following high
and low alarm and warning limits:
●
PV1/PV2AH_Lim
: Limit for high alarm
●
PV1/PV2AL_Lim
: Limit for low alarm
