5.2 Dual Watchdog Operation
Dual Watchdog = Module Wa Host Watchdog
The Module Watchdog is a hardware reset circuit that monitors the operating
status of the module. While working in harsh or noisy environments, the
module may be shut down by external signals. The Watchdog circuit allows the
module to operate continuously without disruption.
The Host Watchdog is a software function that monitors the operating status of
the host. Its purpose is to prevent problems due to network/communication
errors or host malfunctions. When a Host Watchdog timeout occurs, the
module will reset all outputs to a safe state in order to prevent the controlled
target from performing any erroneous operations.
M-7000 series modules include an internal Dual Watchdog, making the control
system more reliable and stable.
For more information regarding the Dual Watchdog, refer to Chapter 5 of the
“Getting Started for M-7026 Modules” manual that can be downloaded from the
ICP DAS website
