PLC Address refers to the PLC network node address setting as
configured on the physical device. If devices share a common Interface,
they require unique addresses. When using DF1 protocol (serial
communications), valid addresses range from 0 to 254 decimal. When
using DH+, valid addresses range from 0 to 77 octal.
PLC Model specifies the particular type of PLC or SLC you are
representing with this object. The PLC Model you select determines
what native data members comprise the object.
