4.4 Configuration
4.4.1 Configuration - CfgData
The CfgData is generated from the modules inserted in the DP configuration tool. When modules are added,
the following rules are to be observed:
Sequence of DP modules to be added in the DP configuration tool
Modules for the coupler's functions [}38]
Complex function modules [}39]
Digital function modules [}41]
For TwinCAT applications, these rules are followed by the TwinCAT system manager. It adds the terminals
or IE modules in the sequence in which they are plugged in, and the modules for functions are added
automatically if the corresponding function is activated in the UserPrmData [}35].
4.4.2 Configuration of the Coupler Modules
The DP modules for the following Bus Coupler functions are to be added first in the DP configuration tool if
the associated function is activated (if the function is not activated, the corresponding DP module is not to be
added):
Function module Activation of the function
2-byte PLC Interface
The 2-byte PLC interface is activated via the UserPrmData [}35] (byte 5, bit 0). By
default it is not active.
K-bus cycle counter
The K-bus cycle counter [}53] is activated via the UserPrmData [}35] (byte 3, bit 3).
By default it is not active.
Dummy output byte
The dummy output byte [}53] is activated via the UserPrmData [}35] (byte 3, bit 5).
By default it is not active.
