Hi everyone!

Does Ignition supports Boolean Array data type for s7-1500 driver?

In the driver, no, you would just need to create a bunch of Boolean tags addressing sequential offsets. The driver will read it in bulk along with any other nearby addresses, there’s no efficiency loss.

If you can connect to the built-in OPC UA server option of the S7-1500 then yes, you can use actual Boolean arrays.
