Character string input
Allocate character string tables to any desired words in the PC. When text is in-
put with a character string input, the new character string will be written to the
character string memory table and the contents of the words allocated in the PC
will be changed automatically. This function allows text to be written from the PT
to the PC easily.
The interlock function can also be used. The character string input is enabled
only while the corresponding interlock bit allocated in the PC is ON.
