Pre-Defined Error Field, Index 0X1003; Communication Cycle Period, Index 0X1006 - WAGO CANopen 752 Manual

7.3.10 Pre-defined Error Field, Index 0x1003

A maximum of 5 errors are entered in the error list. Sub-Index 0 contains the
number of saved errors. On Sub-Index 1 always the error occurred last is
shown. All previous errors are increased by a Sub-Index. If more than 5 errors
occur, always the error on Sub-Index 5 is written over so that always the 5 er-
rors are logged that have occurred last.

The additional information corresponds to the first 2 byte of the additional
Code of the emergency telegram. The error code is like the error code in the
emergency telegram.
If a '0' is written in the Sub-Index 0, the total error memory will be deleted.

7.3.11 Communication Cycle Period, Index 0x1006

This object defines the communication cycle period in µs. If the value is 0 the
object is not evaluated. With help of the index the guarding of the sync objects
is made if e.g. the node guarding can not be used. For a value >0 the module
calculates a guarding time in which the next sync object is expected. If there is
no sync object an emergency object is sent (Error code 0x8100). The module
stays in the current state.
The guarding time is calculated of the communication cycle period (Index
0x1006, in µs) multiplied with the life time factor (index 0x100D). The reso-
lution of the guarding time is in 1 ms steps.
If the life time factor is 0, only the Communication Cycle Period is relevant.
