"On"
You can find general information about the "On" mode in the On chapter.
"Out of service"
You can find general information about the "Out of service" mode in the Out of service section.
The descriptions of the operating modes are identical for SitransP and the APL; refer to the
online help for the standard APL blocks for information on them.
10.1.3
Functions of SitransP
The functions for this block are listed below.
Configuration data
The configuration data comprises units, configuration of the 4 to 20 mA signal and HART
variables, and scaling of the 4 to 20 mA signal. 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 SitransP are only transferred to the device if HART communication
is used (
Feature
Bit2 = TRUE) and the alarm configuration is synchronized with the device
(
Feature
Bit7 = TRUE). No alarm configuration is transferred from and to P420.
The SitransP function block has the following configuration data which can be read out of the
SitransP by means of the "Read configuration data" command:
