Error management
The two HART status bytes (HART device status) that are transferred with each field device
response contain error statements about HART communication, HART commands and the
device status.
These statements are evaluated by the I/O module and provided in the system in maintenance
messages.
Configuration/commissioning
You configure the I/O module in the SIMATIC system with HW Config. Actual analog value
acquisition and HART variable use are configured for the individual channels in the input
address space of the I/O 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 configuration tool.
To reassign parameters of the field devices connected to the I/O module, proceed as follows:
1. You trigger reconfiguration of a field device with a HART command entered using the
SIMATIC PDM configuration tool.
2. Once you have reconfigured 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. As a result of field device reconfiguration, the module triggers a "Configuration changed"
maintenance message if such a message is enabled. This maintenance message is a
notice, not an error, and is automatically deleted by the module after approximately 1
minute.
If enabled, a maintenance message can also be triggered by a new parameter assignment
with the handheld device.
