Avoid reversing current
Reversing current at the outputs may damage the output drivers.
On devices with field bus interface, the outputs, such as "Ready for operation", are
written on both the digital outputs and the field bus outputs. Whether the inputs are
read on the digital inputs or on the field bus inputs is determined in menu 'Additional-
>Communication parameters->Anybus-S Subprint'.
