Error Cause of error
number
81 PLC syntax error:
The same label name was used
twice for a LBL or KFIELD
instruction.
A label name that was imported
with EXTERN from another module
was used again with a LBL or
KFIELD instruction.
A name reserved for internal
modules (9000–9255) was used
with an LBL, KFIELD or EXTERN
instruction.
77 PLC syntax error: A label was set
within a parenthetical calculation.
This is illegal because closing
parenthesis commands cannot be
executed without the associated
opening parenthesis commands.
78 PLC syntax error: A label was
programmed in a connective
operation that was already started.
This is illegal because the first
command behind the label would
then have to be interpreted,
depending on the program, once
as a logical connection and once
as a load command.
70 PLC syntax error: A reference was
made to a label that has not been
defined with BL, KFIELD or
EXTERN.
85 Syntax error: A command was
programmed that gates, assigns
or manipulates the already loaded
logic accumulator even though the
accumulator was not previously
loaded.
83 PLC syntax error: A logic operation
was conducted. However, the
result was not assigned to an
operand, but to a new logic
operation.
133 PLC runtime error: More than one
of the markers M4005 (M03),
M4006, (M04), M4007 (M05) is set.
1124 Compatibility module 9008 has not
been called at the start of the PLC
program. The module is required by
the TNC 426 in order to be able to
process the interface markers of
the TNC 425/407.
67 PLC syntax error: An operand
number was specified that lies
outside the value range for this
operand.
66 PLC syntax error: Operand not
found. A type was indicated for
the operand, but no value.
72 PLC syntax error: The complete
length of the program code to be
generated exceeds the storage
space available in the control.
