Virtual IEC 61131 inputs and outputs

The REC 523 unit offers up to 64 programmable LON inputs and 64 outputs on the
LON bus, 128 in total. The inputs and outputs use the LonMark Standard Network
Variables (NV type 83 = SNVT_state and NV type 22 = SNVT_lev_disc) for
sending and receiving process data.
The LON inputs and outputs are accessible in the relay configuration and can be
freely used for different types of data transfer between the REC units and other
devices that are able to communicate using the network variable of type SNVT_state
or SNVT_lev_disc.
