This section gives the I/O refresh times for CJ-series Units.
 Basic I/O Units
The following table gives the I/O refresh times for Basic I/O Units that are used on the CPU Rack.
The I/O refresh times for these Units on Expansion Racks are approx. 1.5 times the values that are
given in the table.
 Special I/O Units
The following table gives the I/O refresh times for Special I/O Units that are used on the CPU Rack.
The I/O refresh times for these Units on Expansion Racks are approx. 1.5 times the values that are
given in the table.
