Deactivating the process data watchdog

The process data watchdog can only be deactivated if it is in

the "INIT" state. For deactivation, the timeout value is set to

"zero".

Status diagram of the process data watchdog

Fault response acknowledgment

The Net Fail signal can be acknowledged via web-based

management via Modbus, by writing command 0002

hex to

command register 2006 or using the "ETH_ClrNet

FailStatus" function.

Reasons for fault response

The reasons for a fault response and a set Net Fail signal

can be accessed via web-based management, Modbus

register 2004 or the "ETH_GetNet FailStatus" service.
