Adapter Watchdog Timer
Adapter cards that support Peer Cop have a diagnostic watchdog timer that, when
enabled, automatically places the adapter card in the off-line state if the host is inactive
for a pre-configured period.
While the driver is operational, it will always place an adapter card in the off-line state
when transitioning from the on-line to the off-line mode. However, in the event of a
system crash, the driver does not have an opportunity to properly change the adapter
card’s state. In this case, adapter cards that do not support the watchdog timer will not
respond to the command messages, resulting in lengthy timeouts on the Modbus Plus
network. Therefore, we strongly recommend that you enable the watchdog timer for
adapter cards that support it.
Timeout
The user may select the desired timeout interval, or disable the watchdog timer.
The recommended timeout is 2.5 seconds for adapter cards that support the watchdog
timer. For compatibility with older adapter cards, the default value is Disabled.
