HART function

7.2 HART system connection

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 device status (Page 41)

Configuration

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.

To reassign parameters of the field devices connected to the I/O module, proceed as follows:

1. You start the parameter reassignment of a field device using a HART command that you enter

using the SIMATIC PDM parameter assignment tool.

2. After you complete re-parameterization of a HART field device, the corresponding bit is set in

the HART device status of the connected field device (in the 2nd status byte).

3. The re-parameterization 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 65)

If enabled, a maintenance message can also be triggered by a new parameter assignment with

the handheld device.
