Configuring the Distributed I/O (DP)
3.6.7 HART Modules
Requirement:
HART modules are analog modules to which HART transducers can be connected
(HART=Highway Addressable Remote Transducer).
HART modules are required for distributed use with the IM 153-2 (ET 200M).
To assign parameters to the HART transducers, start the parameter assignment
tool SIMATIC PDM
SIMATIC PDM is installed on the programming device/PC.
Representing HART Measuring Transducers
The transducers for HART modules are represented as interface submodules in
the configuration table.
Example: The module is located in slot 4. The transducer for the first channel is
then represented as slot 4.1.
To start SIMATIC PDM:
• Double-click one of the "slots" for HART transducers.
As you can also use the SIMATIC PDM tool for assigning parameters to
PROFIBUS-PA field devices, you can start it as follows:
• Assign a PA field device to a PA master system by dragging & dropping it from
the "Hardware Catalog" window, and then double-click this PA field device.
3.6.8 Configuring Software Redundancy
The configuration of a "warm standby" system consists of:
• Two S7 stations with one PROFIBUS-DP master interface each
(each of these interfaces forms its own subnet)
• One or more slaves with the property "can be used redundantly with active
backplane bus" (e.g. ET 200Ms with IM 153-3) which are connected to both
subnets.
This configuration guarantees that the standby station is able to take over the
processing of the user program if one station (this is, one of the two DP masters)
fails. The slaves that are connected to both stations are then controlled by the
reserve station.
