2-13SectionInputting Character Strings
215
Character strings are input into the character string input field by using the input
key – string and input key – control touch switches or a bar code reader.
For details on the connection and settings of the bar code reader, refer to section
3 of the Setup Manual.
When a character string input field using the interlock function is being displayed
on the screen, the PT continuously reads the status of the corresponding inter-
lock bit allocated in the PC.
Character string input fields only write input character strings to character string
memory table entries; they have no function for directly outputting data to exter-
nal destinations (if a character string is written to the character string memory
table entry for which words have been allocated in the host, the data can be out-
put to the host indirectly).
However, the input of a character string is notified to the host via the PT status
notify area.
Character string input fields have no processing function.
Relationship with Other Elements
• Character string displays (page 148) use the same display method as charac-
ter string input fields.
• For details on how character strings are stored in character string memory
table entries, refer to 2-3-2 Character String Memory Table (page 79).
• In order to use a character string input field, input and confirmation touch
switches are required, unless a bar code reader is used with the automatic
confirmation setting. In cases where there is more than one input field,
switches for selecting and moving input fields are also required (page 341).
• Character string input fields overlap with other elements in accordance with
the order in which they were registered for the screen with the Support Tool.
However, the way in which they overlap can be changed with the Support Tool.
