Connecting panel 800 to siemns PLC
I do have a project that is used Siemens PLC (S7 300 ) the PLC shall be connected to ABB Panel 800
AS i do used the Panel 800 with the compact AC800M that PLC variable that should be used by the HMI shall be configured as Accessible Variables
Such Variables configuration (I understand ) it is applicable is Siemens PLCs
So what to connect the ABB panel 800 with the Siemens S7 300 ?
What is the required configuration since I think the panel with not be able to withdraw the variables from the PLC ?
