6-8 Starting Operation

Note

Switching to the RUN Mode and Starting Operation

Confirming the Communications between the NT631/NT631C and the Host

After completing screen data transmission and setting the communications conditions, connect the NT631/NT631C to the host and start operation.

Check the operation of all screen data and host programs carefully before using them. If incorrect, the system may operate unpredictably.

Press the Quit touch switch on the System Menu screen or other screen. The NT631/NT631C switches to the RUN mode and starts operation.

The operation at the start is as follows.

Display of The System Initialization Screen

When establishing the communications with a host, the System initializing character string is displayed on the screen. If the communications with the host cannot be established, the System initializing screen remains up. If this is the case, check the settings at the host and the PT side, the cables and wir- ing.

In addition, creating screen number 9000 enables the display of a screen other than the System initialization screen.

Transmission of The Contents of Memory Tables

If the Resume Function memory switch is set to ON, or if the initial values of the memory tables are used, the contents of the numeral/character-string memory tables are copied to the allocated words at the host.

↓

Display of The Startup Screen

The startup screen is displayed on reading the contents (screen number of the screen to be displayed) of the first word of the PT status control area.

If the contents are not correct for a screen number, or there is no data regis- tered for the set screen number, an error message is displayed.

Execute the host program and confirm that the following operations are per- formed normally.

•Confirm that the NT631/NT631C screens switch in accordance with the host program.

If the screens do not switch correctly, check the connection between the host and the NT631/NT631C, and also check if the hardware set- tings are correct. For details, refer to SECTION 4 Connecting to the Host from the RS-232C Port, or SECTION 5 Connecting to the Host from the RS-422A/485 Port.

•Confirm that the operation results of touch switch and numeric value/char- acter string input at the NT631/NT631C are sent to the host correctly by displaying the contents of the host words and bits using a Programming Device (e.g. CX-Programmer).

If the results of operations at the NT631/NT631C are not sent to the host correctly, check the setting of the display elements. For details on setting display elements, refer to the description of each display ele- ment in the Reference Manual.
