(2) Output Port
Output ports are numbered from 300 ~ 587. There are 24 inputs and 24 outputs for each I/O board.

l Range of numerical values in the Super SEL
Super SEL uses two types of numbers, integers and real numbers but are subject to the following limitations.
1. Inside the controller
The range of whole numbers that can be accommodated is ±2,147,483,648 and for real numbers the theoretical range
is ±3.4 x 10
38, as a single precision floating point.
2. Limitations in actual use
The programming tool developed initially was an LCD teaching pendant which resulted in certain constraints with
respect to input and output from the program. The numerical values that can be handled from the program are -
9,999,999~99,999,999 for integers and -999,999~9999,999 or -.999999~.999999, in other words an eight digit value
including the decimal point sign for real numbers. Also, when doing floating point calculations, the significant
figure can only be guaranteed up to 7 digits and it will include errors that are particular to floating points.
3. Position data
Internally, position data is handled as whole number data but during the calculation process, these are incorporated
into real numbers and treated as real numbers. There are no problems when dealing with numbers ±9999.999 but
when these are internally calculated as general data and not position data (repeated multipliying and dividing), a
problem arises with the accuracy of the last digit.
When using the Super SEL, please pay close attention to these points. In particular, if you use the CPEQ command
in a comparative calculation using real numbers, you will see almost no correlation. In this case, you will need to use
the CPLE/OPGE command which can view the large and small relations in parallel.
2. Input/Output Port
(1) Input Port
Input ports are numbered from 001 ~ 95 and used for limit switches, sensor switches, etc. There are 24 inputs and 24
outputs for each I/O board.
