SINUMERIK 840D/840Di/810D Operator's Guide HMI Advanced (BAD) – 03.04 Edition
2.6 General sequence of operation
Example: 1 HMI Advanced and 3 NCUs
One HMI unit can be linked to several NCU/PLC units. The machine
control panel MCP is permanently assigned to the NCU.
You can connect an additional programming device (PG) with the
STEP 7 Start-up Tool.
The configuration illustrated below allows several NCUs to be
operated from one HMI, i.e.
· Multiple autonomous machines with multiple NCUs or
· One large machine with multiple NCUs.
PCU 50
MCP1 NCU1
The following rules apply to the operation of several NCUs from one
HMI:
· The NCU being operated is selected via the channel switchover
key and the channel menu.
· The highlighted softkeys in the channel menu show which mode
group/NC/channel the HMI is currently connected.
After setting up a link to another NCU, the operating area selected
last is always available for this (as for the NCU whose link was
separated).
