8.1.4.5.1
Example map
Here is an example of mapping addresses between an external PLC and the SC controller after the I/O
functions have been assigned in the SC controller.
Controller Inputs
External PLC

30001:0
30001:1
30001:2

30001:4

30001:6, 7
30001:8 - 15
30002
#Register:Bit *Byte/Bit
Integer, Float and ASCII data must start on a zero (first) bit of a byte and not in the middle of a byte. Function
code 03 (0x03) can only transmit a 16-bit register, not the individual bits within a register. The PLC will need to
send the 16-bit register and the SC controller will parse the individual bits after receipt.

#Register:Bit *Byte/Bit
Integer, Float and ASCII data must start on a zero (first) bit of a byte and not in the middle of a byte. Function
code 04 (0x04) can only transmit a 16-bit register, not the individual bits within a register. The PLC will need to
capture the 16-bit register and then parse the individual bits after receipt.
