Hart Configuration Tool - Siemens SIMATIC ET 200SP HA Equipment Manual

HART function
7.2 System connection
The I/O module receives the commands, e.g. from the HART configuration tool, forwards them
to the intelligent field device and returns the responses. The interface of the I/O module is made
up of data records that are transferred internally between the IM and I/O module via the ET
200SP HA IO device. The data records must be created and interpreted by the client.

• HART configuration tool (Page 36)
• HART device status (Page 37)
Configuration
You configure the I/O module in the SIMATIC system with HW Config. You configure the
individual channels with respect to the actual analog value output and the use of the HART
variables in the input address space of the module.
You can configure one field device per channel. The configuration/parameter assignment of the
connected field device is then carried out from this configured field device using PDM or the EDD
for the ET 200SP HA.
Parameter reassignment of the field devices
The I/O module generally accepts triggered reconfigurations for field devices. Access rights can
only be allocated in the parameter assignment tool.
You trigger reconfiguration of a field device that is connected to an I/O module with a HART
command entered using the SIMATIC PDM configuration tool. The corresponding bit is set in the
HART device status of the connected field device (in the 2nd status byte) after parameter
reassignment of a HART field device is completed.
The parameter reassignment of the field device causes the analog module to issue a
maintenance message "Configuration changed", if this is enabled. This maintenance message
should be regarded as a notice and not an error. It is automatically deleted again by the I/O
module after approximately 1 minute.
Maintenance events (Page 56)
If enabled, a maintenance message can also be triggered by a new parameter assignment with
the handheld device.
7.2.2

HART configuration tool

Definition
The HART parameters can be set either using an external hand-held device (HART Handheld) or
a HART configuration tool (PDM). Both assume the function of a "client":
The parameter assignment tool affects the entire I/O module; the HART handheld is connected
in parallel to the field device.
