1-2 Part Names and Functions
This section describes the part names and functions, using the 14-point I/O unit as an example. 
 14-point I/O Unit
(1) Memory cassette slot
Used to attach a memory cassette (15). Memory cassettes can be used to 
store backups for CP1L programs, parameters, and data memory. They also 
allow you to copy data to other CP1L units without using a programming tool 
(software). 
(2) Peripheral USB port
Used for connection to a computer. Computers can be used for programming 
and monitoring. 
(3) Analog adjuster
Rotate to adjust the value for auxiliary area A642CH to within the 0 to 255 
range. Use to change timer and counter settings without using a programming 
tool (software). 
(4) External analog settings input connector
Takes an external input between 0 and 10V, and changes the value for 
auxiliary area A643CH to a value between 0 and 256. This input is not 
isolated. 
(5) DIP switches
Used for settings such as write-permission on user memory, automatic 
transfers from memory cassettes, and tool bus use.
