5.6.3 Function keys with LEDs
The function keys (F1 to F7) are provided to jump to other menus during the LCD operation;
the jump destinations are already set as factory default (see Table 5.6-3). However, the user
can program the F1 to F7 keys to jump to user-preferred menus using settings. Incidentally,
the user can program the function key so that a binary signal is generated when the user
presses the function key.
Table 5.6-3 Function keys and jump destinations (default)
Jump destination as default
For testing, the user can also program to generate binary signals when the user presses
the F1 to F7 keys. The F1 to F7 circuits have LEDs; accordingly, the user can also program to
light the LEDs using the settings.
(i) Screen jump pressing the function key
The user can program the F1 to F7 keys as the user-preferred jump keys. For example, when
the user wishes to use the F1 key to jump to another screen, set Screen jump for scheme switch
[Function] in the F1 key (see Table 5.6-6). We shall see the setting in Chapter
User interface:
Setting sub-menu: Configuration of Function keys.
(ii) Binary signal generated pressing the function key
When the user wishes to generate a binary signal upon occurrence of pressing the F1 key, set
Assign Signal for scheme switch [Function] in the F1 key. For instance, if the user wishes to
send a signal generated pressing F1 to the binary output circuit (BO1‡) at the IO#1 slot, set
the Data ID of “FUNC-KEY1(240001 310001730)” for the setting [Input signal 1] of the BO1‡
circuit. Note that the user should set On for the scheme switch [BO1_CPL] when the connection
is done using the setting [Input signal 1]. Figure 5.6-3 shows that a generate signal is outputted
at the FUNC-KEY1 SIGNAL. Table 5.6-7 shows the other FUNC-KEY2 to 7 points. We shall
see the setting procedure in Chapter
User interface: Setting sub-menu: Signal control function.
