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.
