H all
Please help me, i have a big problem, i was trying many time but couldnot find out the way to solve it
In my project
I use 2 PLC and 1 HMI (panelview 1000 component)
in HMi, i want to display all data follow this way
===============================================
when PLC1 in Service ( I use always all bit in PLC1 )
HMI will display all data of PLC1
When PLC1 fault ( by some reason) PLC2 will take over
i sent a bit ( PLC2 OK bit ) of PLC2 to HMI
and HMi will display all data of PLC2
=================================================
but when PLC2 fault, i can back to display all data of PLC1 ( in case PLC1 back service)
cause PLC2 still keep value of bit which sent to HMi
and HMi still work with data of PCL2, although PLC2 fault
==================================================
pls help me how can i do
when PLC2 fault
bit PLC2 sent to HMI have to = 0 (PLC2 OK bit)
to make sure HMi will display data of PLC1
pls try to understand and help me
thanks much
