Power up

Defaults standard functionality
The following defaults are applied (standard M:N = 1:1) if no NETNAMES.INI configuration
file is loaded into the HMI Embedded/OP030/HT6 or if the file cannot be interpreted:
● The bus type used is detected automatically.
● HMI has address 1.
● OP030 has address 10.
● NCU and PLC both have address 13 for an OPI bus.
● NCU has address 3 and PLC address 2 for an MPI bus.
With option
If, however, a special NETNAMES.INI file is created, then it must correspond exactly to the
actual network on account of the special features described below.
If an M:N-capable control unit fails to set up a link to the NCU during power up or if a
configuring error occurs, the control unit switches over to OFFLINE mode. In this mode, the
operator can switch over to the area application via the Recall key and from there to the
commissioning area.
Compatibility
The use of the above defaults guarantees compatibility to all software versions for operator
panel operation.
Power up with HMI Embedded/HT6
An HMI Embedded/HT6 control unit can only set up an active link to the NCU if the
configuration in NETNAMES.INI complies with the description in Section "Structure of the
configuration file". HMI Embedded, HT6 and OP030 can power up in parallel on one NCU,
because as bus nodes they have different addresses. The OP030 can be used as a second
operator panel front with a fixed assignment to an NCU.
If the configured addresses do not match the real addresses (NC/PLC address), the
commissioning engineer can use the following key sequence to power up on an NCU that is
not configured.
