Default – Start address 50000 - Shelved status data for input 1.
Default – Start address 52000 - Internal status data for input 1.
Default – Start address 54000 – Channel Fault status data for input 1.
Port data type -
Address of first data bit = Start address – Port Offset.
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.
No of inputs HI/LO word
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.
