Power up

Differences between HMI Embedded and HMI Advanced
Due to the differences in power-up characteristics, different commissioning procedures are
required.
● HMI Embedded always runs in "M:N" mode, when "M:N" is configured in the
● The mode can be set in the "Commissioning/HMI/Operator panel" menu on the HMI
● The OP030 does not have the functional capability "M:N". It can be used as a second
Commissioning
The NCUs are assigned bus address 13 in the delivery state. Every NCU on the bus must be
allocated its own, unique bus address.
Addresses are assigned in:
● HMI: NETNAMES.INI file
● NCK: In the menu "Commissioning/NC/NCK address"
● MCP: Switch... (address and possibly baud rate, see also /IBN/)

Advanced. The HMI Advanced always runs in a "1 : 1" link with an NCU, the NCU
address can be specified directly. If "M:N" mode is set, then HMI Advanced searches the
NETNAMES.INI file for the names of the specified partners. The addresses are freely
assignable.
Recommendation:
Reserve address 0 (for PG)
Reserve address 13 (for service case: NCU replacement)
operator panel front that is permanently assigned to an NCU("1 : 1" link). The addresses
of the connected partners can be set for this purpose.
Note
It is advisable to make a written record of the procedure (address assignments, etc.)
beforehand.
