A fault is followed by a fault trip after
♦
Watchdog time + 10 ms
♦
The 10 ms correspond to the value 10 of parameter P722 / P695
and
can be neglected with respect to the response-monitoring value.
♦
For additional operation with a Class II master, please bear in mind
the information in the section "Diagnosis with the Class II master" of
Chapter 8.2.10.5.
If the "ON" command (bit 0) is interconnected with the dual-port RAM
interface, the following must be done for safety reasons:
An "OFF2" or "OFF3" command must be additionally parameterized to
the terminal strip/PMU as otherwise the converter cannot be powered
down by means of a defined command when there is a communications
breakdown!

Settings for the PROFIBUS-DP master (Class 1)
PROFIBUS units have different performance characteristics.
In order to ensure that all master systems can correctly communicate
with the CBP in all the ways possible, the characteristic features of the
CBP are summarized in the form of an electronic data sheet (data file).
These so-called master files describe the characteristic features of a type
of unit clearly and completely in an exactly specified format.
For the different master systems, the characteristics are summarized in a
standardized master file (GSD) and, for the SIMATIC, in a type-
description file specific to the SIMATIC.
The CBP2 from V2.21 onwards supports PROFIdrive version 3. The
device master file (GSD) is stored as an ASCII file (SIO28045.GSD) on
the CD supplied with the CBP.
The GSD allows you to configure standard telegrams 1 to 6. It has been
generated according to revision 4 for PROFIBUS DP-V2.
To ensure complete compatibility between CBP and CBP2 V2.10, PPO
types can still be used for configuring purposes, as described below.
The CBP2 from V2.21 onwards can also be operated on the device
master file for the CBP and CBP2 V2.1 (SIEM8045.GSD).
The type-description file is also available as an ASCII file (SI8045AX.200
and SI8045TD.200) on the CD which accompanies the CBP.
