Ethernet I/O Modules
Built-in Dual Watchdog
The Dual Watchdog consists of a CPU Watchdog (for hardware functions) and
a Host Watchdog (for software functions).
The
CPU Watchdog
will automatically reset it-self if the built-in firmware
encounters an abnormal situation.
If there is no communication between the module and the host (PC or PLC)
for a specified period of time (i.e., the Watchdog timeout), the
Host Watchdog
will
set the digital
output based on a predefined safe-value.
I/O Pair-Connection
The I/O Pair-connection function is used to create a digital input to digital output pair through the
Ethernet. Once the configuration is complete, the PETL/tET/tPET series modules can continuously poll
the status of a remote digital input device using the Modbus TCP protocol, and then write to the local
digital output channels in the background.
