commissioning
Introduction
In principle, an NCU 7x0 contains the following components:
• HMI
• NCK
• PLC
• Drive
• CP
The HMI contained in the NCU is designated as internal HMI or as
HMI-Embedded/ShopMill/ShopTurn/HMI sI.
In addition, a PCU 50.3 can be connected to each NCU, on which the HMI-Advanced then
runs (additional optional ShopMill/ShopTurn, HMI sl). This HMI is then designated as
external HMI.
For commissioning, the HMI Advanced Software is required or the commissioning tool
derived from it.
For the commissioning of the PLC, a PG/PC with
SIMATIC STEP7 Version 5.3 Service Pack 3 is required.
In order to connect multiple communication partners to socket X120, a network switch or hub
(e.g. DMC20) is required.
Commissioning components for internal HMI's
Commissioning of an internal HMI requires a PG/PC. This PG/PC is connected via Ethernet
to socket X120.
The internal HMI displays its user interface via TCU (Thin Client Unit), which is connected
via the Ethernet machine control panel (e.g. MCP 310) to socket X120.
Commissioning components for external HMI's
External HMIs are connected to socket X120.
A PC/PG is required for commissioning of the PLC of the external HMI. This PG/PC is
connected via Ethernet to socket X127.
Note
To use the external HMI (PCU 50.3) without TCU, the internal HMI must be switched off.
