3 Configuration Software
 Auto-Clear Processing
The Auto-Clear processing box defines whether or not the PROFIBUS Master Unit should ignore a
failure of this particular slave, when Auto-CLEAR has been enabled in the Master Unit (See Auto-
CLEAR Box on page 69 in section 3-3-1 Configuration User Interface). When Ignore Auto-CLEAR
has been selected, a failure of this particular slave device (i.e. the slave device requests new param-
eters, or fails to respond) will not activate the Auto-CLEAR mode. The Master Unit will however, ser-
vice the slave device.
This feature can be used with slaves which can fail during operation, but for which failure it is not
necessary to switch the entire network to Auto-CLEAR mode.

 Configuration Data Convention
The Configuration Data Convention setting defines how the slave device will handle the special
identifier format data parts of the Check I/O configuration message. The slave can perform the
check either according to the original PROFIBUS DP standard, or according to the PROFIBUS DP-
V1 standard. This allows PROFIBUS DP slaves to use either standard PROFIBUS DP data types or
extended PROFIBUS DP-V1 data types.

will cause an Auto-CLEAR event.
When Auto-CLEAR has been enabled in the PROFIBUS Master Unit, a failure of this particular slave
will not cause an Auto-CLEAR event. The Master will however service the slave device (e.g. send new
parameters).
The Check I/O configuration message will contain PROFIBUS DP-V1 Data type definitions in the spe-
cial identifier format data parts and the slave device will perform the check on this assumption.
