NS-series PTs allow the user to allocate words and bits in any PLC area for use in accessing
the required display contents and storing input data.
Operations that can be performed include reading and writing allocated word contents and bit
status directly, changing the display status of functional objects on the PT screen, and con-
trolling and notifying PT status.
The NS-series PTs also enable communications with more than one PLC. A host name is
registered for each PLC connected, allowing access to any PLC areas by specifying the host
name and address.
