2.2.2Join of Facilities and Application

1.When a facility of the NEAX2400 IMX is controlled by the Application Program (AP) on the UAP computer, the AP and that facility must be connected first. The following is the procedure of this connection.

(a)Set-up of Association

A communication path is to be opened so that the AP can communicate with the facility.

(b)Opening of Facility

The facility that the AP uses is to be declared to the NEAX2400 IMX, and then the AP and the declared facility are joined.

2.Set-up of Association and Opening of Facility

Association is set up by activation from the AP first, and then the association is released along with the stop of the AP. Without this association, the AP cannot communicate with the facility and cannot control the facility, either.

Then, the facility must be opened so as to allow the AP to communicate with the facility through the communication path opened by setting up of the association. Opening of facility is executed on each facility basis.

As a result of the above procedure, the AP becomes able to freely control each of the facilities of the NEAX2400 IMX, and a variety of applications can be programmed on the computer.

2.2.3Cope of Application in changeover of CPU System

Associations established between NEAX2400 IMX and External computer are released when changeover of CPU system executes.

Therefore each application program cap must set up Association again after changeover of CPU system.
