If there is a trigger at the Trg pin, then the Ethernet modem will be
reset , The modem will be startup again until the time "Reset period"
reached.
Channel: Ethernet
Reset period:1—100s
When the Ethernet module had been reset successfully, this block will
output a short trigger.
Description of the function
In order to monitor the communication status of the Ethernet to see if it is normal or continuous(or avoid
the Ethernet module is dead by unknown cause), sometimes we need reset the Ethernet module built-in
in the CPU when the communication has failed or been timeout.
Just one parameter to be set is the "Reset period" as follows:
Here are two examples with detailed description on how to use these blocks in the program.
Example 1
Just as below program shows, after the CPU running, we can push down the digital input1(just need a
short trigger to reset the Ethernet modem), after the Reset period(here is 5s) is reached, the Ethernet
modem will start up and this block will output a short trigger at the same time.
Example2
We also can use such “device reset” block along with the “Com status” function block together in the
program, when there is no data transmission through the Ethernet port while the timeout period(50s) is
reached, the com port status will output HI signal ,and then the Device reset block would be enabled and
the Ethernet module will be reset for the Reset period in the device reset block property dialog box.
