XDROP: Configuring a module rack expansion

Functional description

The function block is used to edit the configuration data for a remote or distributed module rack expansion (via Module XBE) for subsequent processing by module configuration EFBs.

To configure an module rack expansion, the SLOT input in the configuration section is connected to the function blockSLOT input of the DROP function block. The number of XDROP function block input has to be entered at the NUMBER input of the DROP function block. The function blocks for configuration of the analog modules of the I/O stations are connected to the X_SLOT outputs.

NOTE: The function block XDROP is only used to edit the configuration data for a remote or distributedmodule rack expansion, see alsoProcedure for expanding the remote module rack using the XBE module. The configuration of the main module rack expansion is used for the XBE function block.

NOTE: Do not specify Literals at the SLOT inputs of the configuration EFBs. SLOT inputs must be connected to SLOT outputs. Values in SLOT outputs are not supposed to be used directly by the user. They refer to configuration areas in the PLC memory associated to the configured modules. Invalid values will cause a runtime error message in menuTools → Diagnostic Viewer.

and can be configured as additional parameters.
