Recipe Function

Adjusting Contrast and

Brightness During PT

Operation

The new device monitor function can be used to change the PLC’s operating mode or display/change values in the PLC’s memory areas. The present val- ues (PVs) of several words can be listed with the device monitor.

PT operations and inputs can be disabled from the PLC if interlock bits have been allocated in the PLC for the corresponding PT touch switches, numeric inputs, or string inputs.

The following displays can be performed with lamp or touch switch labels:

•Display several lines of labels.

•Switch the display between different labels when OFF and ON.

•Display the numeral memory table contents as labels.

•Display the string memory table contents as labels.

The word configuration of the PT status control area and PT status notify area can be set to emulate those of the NT30/NT30C or NT620S/NT620C/ NT625C; this mode is called NT30/620 compatible mode.

When the PT is operating in NT30/620 compatible mode, it will be equivalent to an NT30/NT30C or NT620S/NT620C/NT625C in the functions listed below. The PT retains full V2 functionality in all functions other than the ones listed below. Refer to Appendix C in the NT31/NT31C/NT631/NT631C Programma- ble Terminal Reference Manual for more details.

•Word configuration and functions of the PT status control area and PT status notify area

•Image/library codes

•Insertion of image/library data into character strings

Data areas in CS/CJ-series PLCs that were previously inaccessible can be accessed. The data areas listed below can be accessed (read/written).

All banks in the EM area, timer completion flags (TU), counter completion flags (CU), Work areas (WR), Task flags (TK), and the HR area.

You can set the data (numeric values) for multiple words in record units using the tabular elements on the PT screen, and write these settings in a single operation to words on the host (i.e., PLC or PT memory) using a touch switch operation on the PT Unit. Also, multiple words of numeric data can be read from the host in one operation. In this way, groups of parameter settings can be edited at the PT Unit, and written to or read from the host.

You can display the brightness and contrast adjustment screen using either the touch switch or commands from the host, even while the PT is in opera- tion.
