Jump widget brings focus to a different page. Mandatory first argument
gives name of the page.
If first path is pointint to HMI_NODE variable is used as new reference
when jumping to a relative page.
Additional arguments are unordered options:
- Absolute: force page jump to be not relative even if first path is of type HMI_NODE
- name=value: Notify PLC about jump by setting variable with path having same name assigned
"active"+"inactive" labeled elements can be provided and reflect current
page being shown.
Exemples:
Relative jump:
HMI:Jump:RelativePage@/PUMP9
HMI:Jump:RelativePage@/PUMP9@role=.userrole#role=="admin"
Absolute jump:
HMI:Jump:AbsolutePage
HMI:Jump:AbsolutePage@role=.userrole#role=="admin"
Forced absolute jump:
HMI:Jump:AbsolutePage:Absolute@/PUMP9
HMI:Jump:AbsolutePage:Absolute:notify=1@notify=/PUMP9
Jump with feedback
HMI:Jump:AbsolutePage:notify=1@notify=.did_jump
