STEP 7, SIMATIC PDM, HART handheld
You can assign the HART parameters either with an external HART handheld device or with
SIMATIC PDM. SIMATIC PDM accesses through the HART analog module while the HART
handheld is connected directly in parallel to the field device.

System environment for HART applications
Transparent message data - Format
The ET°200iSP HART analog modules support the
transparent message data format. Using
SIMATIC PDM you therefore have direct access to the HART field device for the commands
and responses.
Each HART analog module is equipped with a common HART modem for the 4 channels. In
other words, with SIMATIC PDM you can only directly access one channel of the module at
any one time (multiplexes of the channels). It is not possible to simultaneously directly access
another channel of the same module.
