Holding registers
Expansion I/O registers
Adding expansion I/O modules to the 415U will automatically add
the I/O from the 115S modules to the internal 415U-2 I/O store. To
calculate the register location in the I/O store, find the address of
the I/O point in the tables in this appendix, and then add the offset.
The offset is the Modbus address, multiplied by 20.
Examples:
•
Digital input #1 on an 115S-11 with address 5 would be: (5x20)
+10001 = 10101
•
Digital output #2 on an 115S-11 with address 6 would be: (6x20)
+2 = 122
•
Analog input #3 on an 115S-12 with address 3 would be: (3x20)
+30003 = 30063.
•
Analog output #8 on an 115S-13 with address # 7 would be:
(7x20) + 40007 = 40147
