Error counter

NC

static

DW133 is used by the NC computer in order to report errors to the PLC. For
this purpose, DW133 is incremented and is thus unequal to DW001 (error
acknowledgement). After the error message has been evaluated, DW001
must also be incremented by the PLC. This way, the NC computer recognizes
the error acknowledgement and can transmit another error message, if re-
quired.

Error class

NC

® PLC

static

This is where the error class of each reported error is specified. The following
error classes exist:

1 = slight local error
2 = fatal local error
3 = slight global error
4 = fatal global error

Local errors only affect the sub system, which has reported the error. Global
errors always stop or interrupt the currently running DIN program.

Error module

NC

® PLC

static

This is where the module which has reported the error is specified for every
reported error. The following modules can report errors:

1 = axis computer
2 = initialization
3 = interpreter
4 = coupling
5 = PLC runtime system
6 = rough interpolator
7 = memory management
9 = central control
10 = PLC
11 = operating system
12 = CAN
13 = auxiliary routines
14 = communication NC −> MMI
15 = communication MMI −> NC
18 = DS402 conform drive amplifier
19 = Lenze drive amplifier
