Meaning
PLC negatively acknowledges the offline request from control unit.
User has set the HMI switchover disable, control unit cannot go
offline, MMCx_SHIFT_LOCK = TRUE, x=1 or 2, 1st or 2nd HMI-PLC
interface.
PLC issues the online enabling command to the requesting control
unit. Control unit can then go online to this NCU. Content of Z_INFO:
Bit 0 ..3: OK
Bit 4... 7: No. of HMI-PLC online interface with which the control unit
should connect:
First HMI-PLC online interface
Second HMI-PLC online interface
The requesting control unit cannot go online.
Two control units on which uninterruptible processes are in progress
are connected online to this NCU. The PLC cannot suppress either
of the two control units.
The requesting control unit cannot go online.
User has set HMI switchover disable, MMCx_SHIFT_LOCK = TRUE,
x=1 or 2, first or second HMI online interface.
The requesting control unit cannot go online.
Two control units that are both higher priority than the requesting
control unit are connected online to the NCU.
The PLC cannot suppress either of the two control units.
The requesting MMC has gone online.
The PLC now activates HMI sign-of-life monitoring.
Server HMI has disconnected the operating focus from this NCU.
Server HMI would like to disconnect the operating focus from this
NCU and outputs an offline focus request.
PLC positively acknowledges the offline focus request.
Server HMI can disconnect operating focus.
PLC negatively acknowledges the online focus request.
User has set HMI switchover disable, server HMI cannot disconnect
operating focus, MMCx_SHIFT_LOCK = TRUE,
x=1 or 2, first or second HMI-PLC interface.
Server HMI would like to set the operating focus on this NCU and
outputs an online focus request.
PLC positively acknowledges the online focus request.
Server HMI then connects operating focus to this NCU.
PLC negatively acknowledges the online focus request. User has set
HMI switchover disable, server HMI cannot set operating focus,
MMCx_SHIFT_LOCK = TRUE,
x=1 or 2, first or second HMI-PLC interface.
