Array variables through opcua

[BrainBranchetti99]

I would be looking for the possibility of accessing via opc ua in a 1500 cpu.
Is there the possibility of accessing the array locations with a pointer/vector? For example:
var “counter” = 13;
var “ActState”= array[counter].state;

Hello,

OPC UA driver in Rapid SCADA 6 can read arrays from the OPC server. On SCADA level each array element is stored in a separate channel. It’s easier to try and watch how it works.

Isn’t it possible to multiplex the various channels into a single one using a pointer?

Could you provide an example?

Ad example, i need to use on the html page a variable for example “motor state”.

Now.. “MotorState” address is: motors[3].state

If i have 10 motor to show, i need to replicate the variable address 10times.

I prefer having a variable who indicate the actual motor that i need to show, for example “actual motor number” and with the change of this number change the address in to the plc.

If an OPC UA server provides motor states as an array, you can read them as an array and store in a single channel having length 10. But in the scheme view, you need to address channels by their numbers. Provide screenshots of the settings for more details.
