Siemens SIMATIC ET 200iSP User Manual

• The response data record must always be read in full as the data record can be changed by
the I/O module after it is 󹪝rst read with a successful or error status.
If the processing status in the response data record indicates "successful" or "error", the data
record contains current response data or fault displays.
• The client may only write a request data record to the I/O module again when it has read the
response to the previously written request data record via the corresponding response data
record. Otherwise, the response from the I/O module is overwritten.
• The STATUS component in the response frame (HART device status in the response data)
provides information on whether errors have occurred and, if so, which errors.
Each request is stored on a channel-speci󹪝c basis, and the corresponding request data record is
locked. Another writing of the same request data record is thus not possible and is
acknowledged with BUSY.
The disable of the request data record is reset after the termination or completion of the
requested HART command.
A.6.2 HART operating data records
Reading/writing data in RUN
