Appendix C: Expansion I/O Registers
Adding Expansion I/O modules to the WI-I/O 9-U2 will automatically add
the I/O from the WI-I/O-EX-1-S modules to the internal WI-I/O 9-U2 I/O
store.
To calculate the register location in the I/O Store find the address of the
I/O point in the tables below and add the offset.
The Offset is the Modbus address multiplied by 20.
E.g1. Digital input #1 on an WI-I/O-EX-1-S-11 with address 5 would be: (5x20)
+10001 = 10101
E.g2. Digital output #2 on an WI-I/O-EX-1-S-11 with address 6 would be: (6x20) +2
= 122
E.g3. Analog input #3 on an WI-I/O-EX-1-S-12 with address 3 would be: (3x20)
+30003 = 30063.
E.g4. Analog Output #8 on an WI-I/O-EX-1-S-13 with address # 7 would be: (7x20)
+ 40007 = 40147
