3.5.6.2 FB_STRINGToPBox
This function module copies a string (chain of characters) into the P-Box memory array. Via ROW and
COLUMN the starting position of the string is set in the P-Box display. The parameter TEXT communicates
the required string to the function module. The string name can be obtained from the table of variables.
As long as ENABLE is set to 1, all changes at the inputs are adopted immediately.
If the CLEAR input is set, the entire display content is overwritten with spaces before the selected string is
written.
If DONE switches to 1, the string has been transferred correctly.
In case of error, ERROR is set to 1. In this case, DONE is 0. The corresponding error code in the ERRORID
applies.
DONE, ERROR and ERRORID are reset with a negative flank on ENABLE.
