easy Object
The easy object can be used to access easy/MFD functions
via the DeviceNet communication bus. The table below
shows the attributes supported by this object. The 2 bytes of
the attributes 1 and 2 give the diagnostics data of the device.
Attribute 3 can be use to access the outputs (S1 to S8) and
attribute 4 to access the inputs (R1 to R16) of the basic unit.
By using a DeviceNet configuration software (e.g.
RS NetWorx), you can map these data directly to the corre-
sponding memory areas of a PLC.
