Display selection
The relations with the individual steps are shown in the above table by the numbers in
brackets (step numbers).
● The PLC enters the display number in the number word.
● The PLC sets bit0 in the PLC byte for display selection if bit0 and bit7 are set to zero in
the HMI byte.
● HMI Embedded sl acknowledges to the PLC that it has accepted the display selection by
setting bit0 in the HMI byte. At the same time, the value zero is written to bit3 and bit4 in
the HMI byte.
● The PLC resets bit0 in the PLC byte.
● HMI Embedded sl acknowledges to the PLC that the interpreter has started by setting
bit1 in the HMI byte.
● The HMI resets bit0 in the HMI Embedded sl byte.
● Bit2 is set in the HMI byte if the corresponding display appears.
Display deselection
The relations with the individual steps are shown in the above table by the numbers in
brackets (step numbers).
● The PLC sets bit1 for display deselection in the PLC byte if bit1 and bit2 are set in the
HMI byte and bit7 is reset.
● HMI Embedded sl acknowledges to the PLC that it has accepted the display deselection
by setting bit0 in the HMI byte. At the same time, the value zero is written to bit3 and bit4
in the HMI byte.
● HMI Embedded sl acknowledges the display deselection to the PLC by setting bit3 and
resetting bit0, bit1 and bit2 in the HMI byte if the interpreter is terminated.
● The PLC resets bit1 in the PLC byte.
● After display deselection by the PLC or the EXIT command, HMI Embedded sl switches
back to the last selected HMI display.
Error when selecting a display
Bit4 is set in the HMI byte if the interpreter has not responded after 20 seconds or if the
required display cannot be opened.
The states of the HMI that do not support PLC display selection are indicated to the PLC via
bit7 in the HMI byte; e.g., in HMI Embedded sl during switchover between standard and
ShopMill/ShopTurn interface.
