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.
6.5.42 Comport Status
Short description
This function block is used to monitor the communication status of the RS232 (programming port), RS485
port, Ethernet/WIFI port.
With the text message block, we can insert the com port status from such function block for displaying on the
LCD.
