3) I/O Reference Number Setting
The following table shows the I/O reference numbers and points that can be allo-
cated.
Type of Input
CPU10, CPU20, CPU21
Input registers 30001 to 300512
4) Parameter Setting
a) Service Scan: Normal/High-speed
Two types of service scans are available: normal and high-speed. A service scan
is recommended when using the high-speed segment function. The I/O module is
activated before the ladder decoding of the high-speed segments. The I/Os that are
processed in synchronization with the high-speed scan are called High-speed Seg-
ment I/Os. The MEMOSOFT is set by default to "NORMAL."
b) Mode
The number of data input from the Register Input Module can be set.
Either 8CH or 16CH can be set.
The MEMOSOFT is set by default to "16CH."
c) Cycle
The reading cycle of input data can be set.
Any of six cycles listed in the following table can be set according to the set mode.
