FB 9: MzuN Control unit switchover
Description of Functions
This block allows switchover between several control units (operator panels, MMC handheld
units and/or MCP machine control panels), which are connected to one or more NCU control
modules via a bus system.
References:
/FB2/ Function Manual, Expansion Functions; Several Control Panels on Multiple NCUs,
Decentralized Systems (B3)
The interface between the individual control units and the NCU (PLC) is the M : N Interface
in the data block DB 19; see
/FB2/ Function Manual Extended Functions, Chapter "Data lists, Signal description".
FB 9 uses the signals of these interfaces.
Apart from initialization, sign-of-life monitoring and error routines, the following basic
functions are also performed by the block for operating-unit switchover:
