5. Programming for Operator Panel
30 OP1 Rev.1a
5.2.2 String Input
On the Operator Panel, function switch F1 to F6 inputs can be handled as string input.
Function switches F1 to F6 each corresponding to six strings “a” to “f”. When the string
input command (Input #23, a$) is executed in the application, strings corresponding to F1 to
F6 switch inputs can be input.
String a$
a$ = “a”
Print #23, “F1: UP”
Print #23, “F2: DOWN”
Print #23, “F3: LEFT”
Print #23, “F4: RIGHT”
Print #23, “Press any of switches F1 to F4.”
Input #23, a$
If a$ = “a” then
‘ Up processing: Write an up processing program here.
Else if a$ = “b” then
‘ Down processing: Write a down processing program here.
Else if a$ = “c” then
‘ Left processing: Write a left processing program here.
Else if a$ = “d” then
‘ Right processing: Write a right processing program here.
Else
‘ Input error processing: Write an input error processing program here.
Endif
You can display default data in the input area on the Operator Panel by substituting the
string to be input with data before executing the Input command.
If the string to be input is not “a” to “f” when the Input command is executed, “a” is
substituted and “F1” is displayed in the input area.
