Conguration
You congure 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 congure one eld device per channel. The conguration/parameter assignment of the
connected eld device is then carried out from this congured eld device using PDM or the EDD
for the ET 200SP HA.
Re-parameterization of the eld devices
The I/O module generally accepts triggered recongurations for eld devices. Access rights can
only be allocated in the parameter assignment tool.
To reassign parameters of the eld devices connected to the I/O module, proceed as follows:
1. You start the re-parameterization of a eld device using a HART command that you enter
using the SIMATIC PDM parameter assignment tool.
2. After you complete re-parameterization of a HART eld device, the corresponding bit is set in
the HART device status of the connected eld device (in the 2nd status byte).
3. The re-parameterization of the eld device causes the analog module to issue a maintenance
message "Conguration 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.
If enabled, a maintenance message can also be triggered by a new parameter assignment with
the handheld device.
WARNING
Impact of a connected HART handheld
Note that the "O" setting of the "HART gate" parameter is bridged by a connected HART
handheld.

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