    Dear Sirs,

    Please advise and confirm if CAPSA has a built-in filter to filter MODBUS TCP/IP packets and if it is capable to decode it.

    This will be very useful to sniff an industrial network and analyze posible problems with the bandwith.

    Thank you in advance for your help!

    Best regards,

    Luis

    Yes, you can filter MODBUS TCP/IP packets.
    Colasoft Capsa can recognize and decode MODBUS TCP/IP packets.

    To filter MODBUS TCP/IP packets, create a new filter, enable protocol rule, and choose protocol Modbus.

    Dear Sir,

    Thank you for your support.

    I´m trying to figure where can I find Modbus filter option:

    - I have selected Filter from the main menu, next Add button and then select Protocol Rule checkbox and Select button (in the Simple Filter tab).

    - It shows a dialog box "Protocol Rule", but in the options, I can not find Modbus protocol.

    Maybe the software version is not the suitable. I´m using Versión 7.3.1 Build 2436. Should I use other version? Or should I download an actualization or some kind of filters patch or archive?

    Thank you in advance for your support,

    Best regards,

    Luis

    Luis,

    Please upgrade your Capsa to the latest version Capsa 7.7.2.4050.

    Tips: On the dialog box "Protocol Rule", you can click the header "Protocol" to sort the protocols and then choose MODBUS/TCP alphabetically.
