How to Calculate I/O Points of User I/O
The following formula shows the maximum number of user input/output points by setting the maximum input/output size.
Formula
Maximum Number of User Input Points
Standard allocation: Input size [byte] × 8 - 40
RC3 compatible allocation: Input size [byte] × 8 - 24
Maximum Number of User Output Points
Standard allocation: Output size [byte] × 8 - 32
RC3 compatible allocation: Output size [byte] × 8 - 32
Calculation Example
For example, if both the maximum input size and the maximum output size are set to "33" [byte], the maximum user input/output points will be the following.
- Standard allocation:
Maximum number of user input points : 33 × 8 - 40 = 224
Maximum number of user output points : 33 × 8 - 32 = 232 - RC3 compatible allocation:
Maximum number of user input points : 33 × 8 - 24 = 240
Maximum number of user output points : 33 × 8 - 32 = 232
