IDEC OpenNet series User Manual

6: ALLOCATION NUMBERS
OPENNET CONTROLLER USER’S MANUAL 6-19
Example:
The system setup shown above will have operand numbers allocated to each module as follows:
In the system setup shown above, the analog input module in slot 5 uses link register L300 for channel 0 data and L304 for
channel 4 data.
Bit Designation of Link Register
The following table illustrates how to read and write link register bits primarily used for basic instructions and some
advanced instructions as bit operands.
Link Register Mapping for Functional Modules
Each functional module has eight channels of data areas. One channel consists of one link register which can process one-
word data, or 16 bits. Functional module data is addressed for bit operands in the following formula:
Slot No. Module Operand Numbers
1 Functional Module 1 L100 through L127
2 Output Module 1 Q0 through Q7, Q10 through Q17, Q20 through Q27, Q30 through Q37
3 Functional Module 2 L200 through L227
4 Output Module 2 Q40 through Q47, Q50 through Q57
5 Functional Module 3 L300 through L327
6 Input Module 1 I0 through I7, I10 through I17, I20 through I27, I30 through I37
