3. The maximum cable length is limited to 2 m when an NT-AL001-E Link
Adapter is connected.
4. Branch lines must be a maximum of 10 m long.
NT Link Communications NT Link communications are used to connect an OMRON Programmable
Controller (PLC) and Programmable Terminal (PT). Up to 8 PTs can be con-
nected to one PLC. For details on the system configuration, refer to the user’s
manual for the PT.

Simple Backup Function The CPU Unit’s Simple Backup Function can be used to backup the Protocol Macro
data in the Serial Communications Board/Unit to the CPU Unit’s Memory Card. The
backed-up data can be restored or compared.
(The Simple Backup Function can be used with CS1-H CPU Units only.)
