Controller functions
Version 1
RES-406
Page 37
As of GSD Version v1.6, the calibration temperature can be activated for setting by means of the input data by
selecting the value "-1" in the parameter data. The calibration temperature can then be specified via the "Set point/
AC temperature input data (
section 7.5.1 "Automatic zero calibration "AUTOCAL" (AC)" on page 28).
You do not need to execute the AUTOCAL function after changing the calibration temperature.
7.7.5
Heating time limit
The heating time limit provides additional protection against unwanted permanent heating. The controller automat-
ically deactivates the heating impulse after the set heating time limit has elapsed if the start bit remains set for
longer than the time specified by this limit. The start bit must be reset before the controller can be started up again.
The heating time limit is deactivated as default (0), but can be set to any value between 0s and 25.0s (0 and 250).
7.7.6
Extended controller diagnosis
The extended controller diagnosis uses the diagnostic function of the PROFIBUS protocol to display several faults
of the RES-406 on the PROFIBUS master directly. For each fault there is a text message stored in the device
master file so the error codes appear on the PROFIBUS master in plain text if the master has the capability to
display text messages.
With the help of parameter No. 9 the extended controller diagnosis can be activated or deactivated. The default
setting is "activated".
Although the extended controller diagnosis ist deactivated, there is the fault diagnosis which is coded in the pro-
tocol.
This paramter is available on all controllers manufactured as of June 17, 2002 and supplied with
GSD Version v1.2.
DPV1 protocol extension (alarm model):
The extended device diagnostic functionality is not available with the DPV1 protocol extension and GSD
Version v2.0 or higher (
section 7.8 "DPV1 protocol extension (as of GSD Version v2.0)" on page 42. The DPV1
alarm model (
section 7.8.2 "DPV1 alarm model" on page 42) must be used in this configuration instead. In this
case, parameter no. 9 in the GSD file switches the so-called DPV1 diagnostic interrupt on and off.
If you want to keep the old extended device diagnostics (e.g. for reasons of software compatibility), you must use
a GSD version previous to v2.0. The DPV1 functionality for the RES-406 is then automatically deactivated in the
PROFIBUS master.
7.7.7
Measuring impulse duration
The length of the measuring impulses generated by the controller can be set with parameter no. 10. It may be
necessary to set a measuring impulse that is longer than the default 1.7ms for certain applications.
This parameter is available on all controllers manufactured as of July 14, 2003 and supplied with
GSD Version v1.3.
7.7.8
Data format
This parameter specifies the order of the bytes (Intel: "high/low byte", Motorola: "low/high byte") in the cyclic data
for both input and output data (
section 7.4 "PROFIBUS protocol" on page 26). We recommend setting "low/high
byte (Motorola)" for Siemens controllers.
This parameter is available on all controllers manufactured as of July 23, 2004 and supplied with
GSD Version v1.4.
