Several Operator Panels on Several NCUs, Distributed Systems (B3)
2.2 Several operator panel fronts and NCUs with control unit management option
III. Bus identification
Defines which bus the HMI is connected to:
Element
[param network]
bus =
opi: Operator panel front interface with 1.5 Mbaud
mpi: Multi-point interface with 187.5 Kbaud
Note
The baud rate is automatically detected on the HMI Embedded/HT6.

In the case of HT6, the integrated MCP is always switched over simultaneously. The
integrated MCP is responsible for address assignments of HT6. Only values between 1 and
15 are possible for this reason.

simultaneously switched over.
If none is implemented, there is

State after power up.
If ONLINE, link is set up via
DEFAULT channel entry to the
associated NCU.
OFFLINE: No link is set up
immediately after power up.
Important: In addition, it is
necessary to set the entry

Example
[param network]
bus = OPI
Example
[param MMC_1]
mmc_typ = 0x40
HMI is both server and main
control panel
See below for explanations
mmc_bustyp = OPI
mmc_address = 2
mstt_address = 6
or mcp_address = 6
name = HMI_LINKS
start_mode = ONLINE
(During power up HMI is
connected online to the NCU to
which the channel is assigned
via channel data (see VI)
DEFAULT_logChanGrp,
DEFAULT_ log_Chan).
