System address
Range is 0x00 (0) to 0xFE (254). Default is 0x00.
Start address HI/LO word
Indentifies first data bit to be read. The data type returned for this address depends on
a number of factors. Standard systems supplied before August 2011 can only return
contact data in the range 0 to 1984:-
Address of first bit = Start address.
Address 0 will contain contact data for inputs 1.
Address 1 will contain contact data for inputs 2.
Address 254 will contain contact data for inputs 255.
Address 255 will contain contact data for inputs 256.
Etc.
Bespoked systems supplied before August 2011 may have additional data types
available, please contact RTK for specific information / manual.
After August 2011 all systems have the data types, contact offset and port offset
functionality defined below:-
There are two data groups containing data types these are listed below together with
their default address range. Contact and port offsets are assumed to be 0:-
Status Group – Data types
o
Contact,
Address range 0 – 1984 max.
o
Alarm,
Address
range 2000 – 3984 max.

ddress
range 14000 – 15984 max.
Port Group – Data types
o
Coil,
Address range 16000 – 17984 max.
The data type returned depends on the combination of Start address, Contact Offset,
Port Offset and number of inputs.
Note: If status and coil first data bits overlap “coincide” the data type returned will
always be Status.
