Invalid Control Sequences
If an incorrect control sequence is detected, the invalid portion will be
displayed as part of the string.
For example, in the display area shown earlier, the string: “ESC[3;0HThis
sequence is invalid” would be invalid: the display is 10 characters by 3
lines, and a line specification of 3 would start printing at the fourth line.
If the current display position were 0;0, the string would display:
←
[3;0HThis
sequence is
invalid
The left arrow character in the display represents ESC.
Other invalid sequences:
nested Reverse Video On, for example, “ESC[7mOneESC[7mTwo” The
second command is invalid and if possible will be displayed as part of
the string
nested Reverse Video Off, for example, “ESC[27mOneESC[27mTwo”
The second command is invalid and if possible will be displayed as part
of the string
wrong characters in text position sequence. The text position
coordinates must not contain any characters other than 0 to 9, for
example, “ESC[a3;4HThe string”
The ASCII Input object allows the operator to send an ASCII string to a
PLC input address.
On the Large ASCII Input object for a Touch Screen terminal, the operator
selects characters by touching them on the screen. The selected character
appears in the scratchpad. When the string in the window is complete, the
operator sends it to a preconfigured PLC address by pressing the ENT key.
