D.)
Output of the error number over actual value output 0…10 VDC (terminal 17+18):
As a temperature display is not required in case of malfunction, the actual value output is used to output the error
in case of alarm.
Offered for this purpose, within the 0…10 VDC range, are 13 voltage levels, each of which has one error number
assigned. (
section 8.19 "Error messages" on page 49).
For statuses that require AUTOCAL, or when the device configuration is not correct (error no. 8…12, or 104…106,
111…114, 211, 302, 303), the actual value output switches back and forth between the voltage value that corre-
sponds to the error and the end value (10 VDC, i.e 300 °C or 500 °C) with 1 Hz. If the START signal is output
during these statuses, the voltage value no longer changes.
An alarm message can be reset by activating the RS bit or by switching the controller off and on.
Resetting the alarm message using the RS bit becomes effective only when the RS bit is deactivated.
Invalid alarm messages can occur when the controller is switched off due to the undefined operating status. This
must be considered in evaluating the higher-level controller (e.g. PLC) to avoid false alarms.

Error messages
Besides the error diagnosis coded in the protocol, the PROFIBUS diagnosis (expanded device diagnosis) can also
be accessed. The error numbers appear as plain text in the project design tool, as they are stored in the GSD file.
The following table shows the assignment of the output error numbers to the errors that occur. In addition, the
cause of the errors and the necessary measures to remedy them are described.
The simplified circuit diagram in section 8.20 "Error ranges and causes" on page 53 permits fast and efficient error
remedy.
Thirteen voltage levels for diagnosing errors appear at the CIRUS
®
temperature controller’s actual value output.
The error messages are even more finely differentiated internally. The 3-digit error codes described below can be
displayed via the PROFIBUS interface or in the ROPEX visualization software (
section 8.12 "USB interface for
visualisation software ROPEXvisual
®
" on page 46). The error search can thus be performed even more effec-
tively.
Evaluation of the actual value output for detection of an error message - e.g. in the higher-order
controller - must be done with an adapted tolerance window to avoid incorrect evaluations. The tol-
erances of the actual value output must be observed (
section 6 "Mounting and installation" on page 8).
