Communication variables between Applications in two controller (AC800M)
My objective to pass data/signal between controller of each Application program of different controller .
I had done set an communication variable ( Variable1 , direction:in , ip address:controller 2 for Application 1, Program1, Controller1, ) and ( Variable1 , direction:out, ip address:controller 2 for Application 2,Program1, Controller2).
I tried on test mode set value on Application 2 communication variable 1, but Variable 1 on Application 1 did not change according to follow Application 2.
Any help or explained much appreciated.
