CP1E CPU Unit Software User’s Manual(W480)
Introduction
Thank you for purchasing a SYSMAC CP-series CP1E Programmable Controller.
This manual contains information required to use the CP1E. Read this manual completely and be sure
you understand the contents before attempting to use the CP1E.
This manual is intended for the following personnel, who must also have knowledge of electrical sys-
tems (an electrical engineer or the equivalent).
•Personnel in charge of installing FA systems
•Personnel in charge of designing FA systems
•Personnel in charge of managing FA systems and facilities
CP-series CP1E CPU Units
•Basic Models CP1E-ED-
A basic model of CPU Unit that support basic control applications using instructions such as
basic, movement, arithmetic, and comparison instructions.
•Application Models CP1E-N/NAD-
An application model of CPU Unit that supports connections to Programmable Terminals, invert-
ers, and servo drives.
The CP Series is centered around the CP1H, CP1L, and CP1E CPU Units and is designed with the
same basic architecture as the CS and CJ Series.
Always use CP-series Expansion Units and CP-series Expansion I/O Units when expanding I/O
capacity. I/O words are allocated in the same way as for the CPM1A/CPM2A PLCs, i.e., using fixed
areas for inputs and outputs.
