Error Cause of error

112 PLC runtime error:
The processing of the cyclically
executed program section takes
too long. Check the program
substructure for very compute-
intensive sections that you can
start as submit jobs.
The displayed processing time
might increase during data transfer
and in handwheel mode. In case
of doubt, select handwheel mode
and simultaneously start data
transfer with max. baud rate, then
check "MAXIMUM PROCESSING
TIME" in the PLC programming
environment. Values should not
exceed 150% (safety reserve in the
event of unfavorable operating
conditions).
113 PLC runtime error: The operand for
the CASE statement contains a
value that cannot be interpreted as
an offset in the CM table (smaller
than 0, or greater than or equal to
the table length).
65 PLC syntax error - invalid operand
type: An unkown operand type was
given, or the command cannot be
used for the given operand type.
114 PLC runtime error — subprogram
was not defined.
84 PLC syntax error: A command was
programmed that logically
connects, assigns or manipulates
the loaded word accumulator,
although the word accumulator was
not previously loaded.
82 PLC syntax error: A word gate was
executed but the result had not
been assigned to any operand, and
a new gate had begun instead.
69 PLC syntax error: The line is longer
than 128 characters.
109 PLC runtime error:
You attempted to nest more than
32 module calls.
You programmed a recursive
module call that exceeds the limit
of 32 levels.
91 PLC syntax error: A CASE table
was programmed with more than
128 entries.
2317 More than 15 events were defined
for the current SPAWN process
(cooperative multitasking).
101 PLC syntax error: A total of more
than 1,000 global labels were
defined within the associated files.
74 An attempt was made to nest more
than 16 parenthetical expressions in
each other.
