Example below with Port offset = 0:-
Default – Start address 16000 - Coil data for input 1.
Example below with contact offset = 40000:-
Default – Start address 56000 - Coil data for input 1.
Note: If status and coil first data bits overlap “coincide” the data type returned will
always be Status.

Number of data bits to return. Maximum allowable number of data bits “channels” to
read with single message is 1984.
Status data type –
Address of Last data bit =
(No of inputs – 1)
+
(Start address - Contact Offset).
Port data type -
Address of Last data bit =
(No of inputs – 1)
+
(Start address – Port Offset).
Note: If status and coil first data bits overlap “coincide” the data type returned will
always be Status.
