D - EXPANSION I/O REGISTERS
Adding 115S Expansion I/O modules to the WI-MOD-xxx-E-5W will automatically add the I/O to the internal WI-
MOD-xxx-E-5W 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 slave address, multiplied by 20.
Examples:
•
Digital input #1 on an WI-EX-IO-11 with address 5 would be: (5x20) +10001 = 10101
•
Digital output #2 on an WI-EX-IO-11 with address 6 would be: (6x20) +2 = 122
•
Analog input #3 on an WI-EX-IO-12 with address 3 would be: (3x20) +30003 = 30063.
•
Analog Output #8 on an WI-EX-IO-13 with address # 7 would be: (7x20) + 40007 = 40147
