In this article we will cover the process on updating the digital filter on your WISE 4050/1 Series PLC.
Instructions
In order to adjust your PLC’s digital filter settings, you will need to reconfigure the channels on your PLC, to begin you will need the following:
- Laptop on the same network as the PLC
- PLC IP Address:
- If connected to an OFS Router, you will need to enquire with OFS Support (support@ofsystems.com) on acquiring the Router's Wi-Fi detail, connecting to the network, and then accessing the PLC via it's IP address, this will likely be 10.17.XX.X.
- If the PLC is connected to your network, you will need to identify the IP address that has been assigned to the PLC you wish to update.
Once you have all these things ready to go, please head to the following page in your browser:
Once the page has loaded you should be greeted with the following login prompt:
You will be able to login using following credentials:
- Username: root
- Password: 0000000 (8 x Zeros)
Once successfully logged in, you should arrive on the following overview page:
If you have successfully logged in you can head to I/O Status —> DI —> Configuration, once here you will need to select the channel you want to adjust from the dropdown and change the following settings (As shown in screenshot below):
Settings to adjust the digital filter
- Min. Low Signal Width: 10 (Default Value)
- Max. High Signal Width: 10 (Default Value)
Here you can adjust the debounce time. Our default configuration is 10 * 0.1ms (which means we need to see a minimum 1ms high, and a 1ms low signal in order to count a signal).
We recommend first adjusting the Min. Low Signal Width to alleviate this behaviour.
You can adjust this filter per channel until you believe the PLC is no longer picking up any additional counts.
Once these settings have been updated, press the green submit button.
You will need to use the process of trial and error here until you adjust all the channels you are using and you believe there are no more additional counts being detected.
