The table below describes the Modbus/TCP data areas that contain the states of the virtual
outputs of the PNOZmulti 2.
Relevant areas for the data are defined in the Modbus/TCP data areas Discrete Inputs (1x)
and Input Register (3x). Read access is available to these data areas.

A watchdog can be activated in Control Register 255.
If no input bits are set by a Modbus/TCP subscriber within the preset time, the PNOZmulti 2
will set the input bits to "0".
