Error code indicated via the actual value output 0…10 VDC (terminals 17+18):
Since a temperature indication is no longer necessary if a fault occurs, the actual value output is used to display
error messages whenever a fault is signalled.
Thirteen voltage levels are available for this purpose in the 0…10 VDC range, each of which is assigned an error
code (
section 8.19 "Error messages" on page 46).
If a state that requires AUTOCAL occurs – or if the device configuration is incorrect – (error codes 104…106,
111…114, 211, 302, 303), the signal at the actual value output jumps back and forth at 1 Hz between the voltage
value corresponding to the error and the end of the scale (10 VDC, i.e. 300 °C or 500 °C). If the START signal is
present in one of these states, the voltage value does not change any more.
If a ROPEX temperature meter (e.g. an ATR-x) is connected to the controller’s analog output, the temperature
indication can be directly assigned to the error codes if an alarm is signalled.
An error message can be reset by setting the RS bit or by momentarily interrupting the power to the controller
(24 VDC supply voltage).
If an error message is reset with the RS bit, it is not actually reset until the RS bit is reset.
Invalid error messages may appear when the controller is switched off owing to the undefined operating state. This
must be taken into account when they are evaluated by the higher-level controller (e.g. a PLC) in order to avoid
false alarms.

Error messages
In addition to the error codes diagnosed in the event protocol, you can also access the PROFINET diagnosis func-
tion (extended device diagnosis). The error codes appear in the configuring tool in plain text because they are
stored in the device master file (GSDML).
The table below shows the meaning of the error codes. It includes a description of each error as well as the
required corrective action.
The block diagram in section 8.20 "Fault areas and causes" on page 50 helps you clear a particular error quickly
and efficiently.
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 PROFINET interface or in the ROPEX visualization software (
section 8.12 "USB interface for
visualization software ROPEXvisual
" on page 43) to facilitate troubleshooting).
If the actual value output is evaluated in order to identify an error message – in the higher-level con-
troller, for instance – the tolerance window must be adjusted to prevent incorrect interpretations.
Please note the tolerances of the actual value output (
section 10 "Technical data" on page 52).
