Channel Errors

Error(Hex)

Error(Dec)

Error type

Description

4101

16641

Parameter

Group index not allowed

The location within the channel specified for a group is not allowed.

4102

16642

Address

Null pointer

The pointer to the group is invalid. This is usually a consequence of an error at system start-up.

4103

16643

Internal

Missing process image

It is not possible to exchange data with the PLC.
Possible causes:
1. The channel has no interface (no interpreter available).
2. The connection to the PLC is faulty.

4104

16644

Parameter

M-function index not allowed

Unacceptable M-function (not 0...159) detected at the execution level.

4105

16645

Memory

No memory

No more system memory is available. This is usually the result of another error.

4106

16646

Function

Not ready

The function is not presently available, because a similar function is already being processed. Usually this is a result of access conflicts: more than one instance wants to issue commands to the channel. This can, for example, be the consequence of an incorrect PLC program.

4107

16647

Function

Function/command not supported

A requested function or command is not supported by the channel.

4108

16648

Parameter

Invalid parameter while starting

Parameters to start the channel (TwinCAT-Start) are invalid. Typically there is an invalid memory size or channel type requested.

4109

16649

Function

Channel function/command is not executable

A channel function e.g. interpreter start is not executable because the channel is already busy, no program is loaded or in an error state.

410A

16650

Function

ItpGoAhead not executable

The requested ItpGoAhead command is not executable, because the interpreter is not executing a decoder stop.

4110

Error opening a file

The specified file does not exist. Example: NC program unknown.

4111

4119

16665

NC programming

Error while loading the NC program

The program name is too long.

4120

16672

NC programming

Divide by Zero

The NC encountered a computation error during execution: division by 0.

4121

16673

NC programming

Invalid circle parameterization

The NC has detected a calculation error during processing: the specified circle is not calculable.

4122

16674

NC programming

Invalid FPU-Operation

The NC encountered an invalid FPU-Operation during execution. This error occurs e.g. by calculating the square root of a negative number

4130

16688

NC programming

Stack overflow: Subroutines

The NC has detected a stack overflow while processing: Too many subroutine levels.

4131

16689

NC programming

Stack underflow: Subroutines

The NC has detected a stack underflow while processing: Too many subroutine return commands.
A main program must not be terminated with a return command.

4132

16690

NC programming

Stack overflow: Arithmetic unit

The NC has detected a stack overflow during processing: the calculation is too complex or is not written correctly.

4133

16691

NC programming

Stack underflow: Arithmetic unit

The NC has detected a stack underflow during processing: The calculation is too complex or is not written correctly.

4140

16704

Parameter

Register index not allowed

The NC has detected an invalid register index during processing: The program contains an invalid specification (not R0...R999) or a pointer register contains an invalid value.

4141

16705

NC programming

G-function index not allowed

The NC has encountered an unacceptable G-function (not 0...159) during execution.

4142

16706

NC programming

M-function index not allowed

The NC has encountered an unacceptable M-function (not 0...159) during execution.

4143

16707

NC programming

Extended address specification not allowed

The NC has encountered an unacceptable extended address (not 1...9) during execution.

4144

16708

NC programming

Index to the internal H-function not allowed

The NC has encountered an unacceptable internal H-function in the course of processing. This is usually a consequence of an error during loading.

4145

16709

Parameter

Machine data value not allowed

While processing instructions the NC has detected an impermissible value for the machine data (MDB) (not 0…7).

4150

16720

Parameter

The NC has encountered an error by the calculation of the tool compensation.

4152

16722
