Commissioning; Compiling The Configuration List - Festo CP-FB11-E Programming Manual

2.1.2 Compiling the configuration list

Configuration list
Ascertaining the
configuration
2−4
Before commissioning or programming, compile a configur
ation list of all connected field bus slaves. On the basis of this
list, you can:
carry out a comparison between the NOMINAL and the
ACTUAL configurations in order to ascertain if there are
any connection faults
accesss these specifications during the syntax check of a
program, in order to avoid addressing errors.
Configuration of the CP system requires a very accurate pro
cedure, as different configuration specifications are some
times required for each system, due to the modular structure.
Please observe here the instructions in the following sections.
The configuration data must be known or ascertained for
each bus slave. Ascertain here the address range occupied
by the CP system.
Address assignment of the CP system
The size of the address range occupied by the CP system de
pends on the number of the last used string (see also manual
CP system"). The last used string as well as all numerically
lower strings each occupy 16 input addresses and 16 output
addresses.
If no string is occupied, the node will respond to the field bus
as standard with 2 occupied inputs and outputs (e.g. for test
purposes).
