Diagnosis Of The Outputs, Index 0X5900 - WAGO CANopen 752 Manual

44 • CANopen
The state is coded as follows:
State:
Pre-Operational
Operational
Prepared
The life time is the product of guard time (Index 0x100C) multiplied by the
Life Time Factor (Index 0x100D).
7.3.15.1 Failure of Node Guarding
If the Life Time is over without receiving a Node Guard Telegramm by the
module, an emergency telegram (Error Code: 0x8130, Error Register: 0x11,
Additional Code: 0x00 04 00 00 00) is set.
A failure of the Node Guarding is a communication error. A status change of
the CANopen Software (Standard: PRE-OPERATIONAL) occurs according
to the entry in the index 0x67FE Sub-Index 1, and the guarding failure is indi-
cated by the LED flashing fast. The outputs are set according to index 0x6206
and 0x6207.
As soon as the Node Guarding Protocol starts again, the previous flashing
code will be displayed, the module and the outputs stay in the state and a
Emergency Telegram (Error Code: 0x0000, Error Register: 0x11, Additional
Code: 00 04 00 00 00) will be sent, to indicate that the Node Guarding is re-
started.

7.3.16 Diagnosis of the Outputs, Index 0x5900

The diagnosis information is switched active ('1'), when the status of an output
pre-defined by the CANopen no longer coincides with the internally read back
status. Each bit in the diagnosis byte is assigned to the corresponding bit in the
output byte.
Causes for the activation of a diagnosis message:
• Missing power supply for the output classes
• Short-circuit of an output line
• Internal malfunction of an output class.
The internal processing of the output information extends a pending diagnosis
message to a duration of at least 1s.
With diagnosis requests pending, the module sends am Emergency Message
(Error Code: 0xFF00, Error Register: 0x81 Additional Code: 0x01 XX XX 00
00). Simultaneously the overload light diode is activated
