Diagnostic interface

The diagnostic interface for the CPX terminal makes it possible to locate a malfunction to a specific
component of the CPX terminal or of the Motion Terminal. For details, see system description of the
CPX terminal (è 1.1 Applicable documents).
The source of the malfunction within the Motion Terminal can be identified using the channel informa-
tion.

Input channel E0
Output channel A0
Tab. 100 Assignment of the channel numbers (without additional CPX modules)
Channels E2 ... E9 und E11 ... E18 correspond to the individual inputs (0 ... 7) of the respective input
module.
Depending on the structure of the CPX terminal, the channel numbers shown above must be added to
the number of the I/O channels that can be assigned to additional modules in the CPX terminal.
Example
If another digital input module having 8 input channels (0 ... 7) is installed between the bus node and
the Motion Terminal controller, the Motion Terminal controller uses channels E8 und A0.

Diagnostics channel in transfer mode

By means of the transfer mode, the Motion Terminal provides diagnostic information which, independ-
ent of the CPX error number, enables more precise analysis of the cause of the malfunction.
