Diagnostics and error handling

5.1

Summary of diagnostics options

The CTEL master module supports various options for diagnostics and error handling in the CPX termin

al. An overview is provided by Tab. 5.1.

Diagnostics option

Explanation/advantages

Detailed description

Error messages

The CTEL master module reports specific

malfunctions as error messages (error

numbers) to the CPX bus node.

Advantage: Error messages can be evaluated

via the CPX bus node, operator unit or FMT.

5.2

CPX system description

(P.BE-CPX-SYS-…)

LED display

The CTEL master module reports specific

malfunctions as error messages (error

numbers) to the CPX bus node.

Advantage: Fast “on-site” error detection.

5.3

Status bits, I/O

diagnostic interface

and specific diagnostic

functions

The errors recognised by the CTEL master

module are reported in some cases to the

CPX bus node with special additional

information.

Advantage: Fast access to error messages

via the fieldbus, etc.

5.4

CPX bus node description

Diagnostics via the

operator unit

Diagnostic information can be displayed on

the operator unit in a convenient and

menu-driven manner.

Advantage: Fast “on-site” error detection.

5.5

Operator unit description

(P.BE-CPX-MMI-1-…)

Diagnostics via the

Festo Maintenance

Tool (FMT)

The CPX-FMT offers the option to display

diagnostic information at a PC.

Advantage: Fast “on-site” error detection;

diagnostics also possible from a higher

automation level

Note

The available diagnostic information may depend on the settings of the CPX bus

node or on the parameterisation.
