4.3.7 Address Map
The I/O data store provides storage for all I/O data, either local or received from the
system.
The I/O Store provides four
different “register types”; two bit registers, two word
registers, two long-word registers and two floating point registers. In addition each
register type supports both inputs and outputs making a total of eight different register
addresses that are used for physical I/O and Gateway Storage.
These files are mapped into the address range as described below.
Type Size Address
discrete outputs 3000 (bits) 00001
discrete inputs 2500 (bits) 10001
Word (unsigned) inputs (16-bit) 2500 (words) 30001
word (unsigned) outputs(16-bit) 2500 (words) 40001
long inputs (32-bit) 20 (longwords) 36001
float inputs (32-bit) 20 (floats) 38001
long outputs (32-bit) 20 (longwords) 46001
float outputs (32-bit) 20 (floats) 48001
The addressing utilises standard Modbus protocol formatting as well as being common
for WEIDMULLER protocol.
