Local outputs: QW0/
outputs of the network station: QW1 – QW8
The local outputs can be read directly via DeviceNet, and from Pico
GFX version 04 they can also be written. However, the outputs are
only switched externally if the device is in Run mode and the
addressed output is not being used in the circuit diagram. Refer
to Read/write image data on page 7-7.
