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
● HMI Embedded sl acknowledges to the PLC that it has accepted the display selection by
● The PLC resets bit0 in the PLC byte.
● HMI Embedded sl acknowledges to the PLC that the interpreter has started by setting
● 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 Embedded sl acknowledges to the PLC that it has accepted the display deselection
● HMI Embedded sl acknowledges the display deselection to the PLC by setting bit3 and
● The PLC resets bit1 in the PLC byte.
● After display deselection by the PLC or the EXIT command, HMI Embedded sl switches
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.
