Communications with PLC by Direct Connection

Section 1-4

Functions of the PT Status Control Area (PLC to NT20)

The “PT status control area” is used to control the NT20 status. When data is
written to this area in the PLC, the NT20 reads the contents and operates
according to the contents.

Example of the PT Status Control Area Application

When data is written to the PT status control area, the NT20 will operate as
given below.

Functions of the PT Status Notify Area (NT20 to PLC)

The “PT status notify area” is used to notify the PLC of changes of the NT20
status. When a change is made in the NT20 status, the change is written to
this area in the PLC. By reading the data from the area, the NT20 status can
be checked.

Example of the PT Status Notify Area Application

When a change is made in the NT20 status, such change will be indicated in
the PT status notify area as described below.

Connecting to PLC from Other Companies

The NT20 can be connected to PLCs from other companies using the com-
puter link method.

Connectable PLCs

The NT20 can be connected to the following PLCs.

• Mitsubishi A-series Sequencers (via Computer Link Unit)

• Mitsubishi FX-series Sequencers

Refer to the

PLC Connection Manual

(Cat. No. V042) for connection methods.

NT Series Support
Software

The following Support Software is required when connecting PLCs from other
companies.
