    I installed your Rapid Scada software for a proof of concept, more precisely to test the control of some BC9100 PLC’s from Beckhoff, using Modbus.
    I read your documentation and in order not to reinvent the wheel, I asked for your help with the questions below:
    1 – What is the best way to send the Date and Time to the PLC?
    2 – Is there a standard way to extract a “Bit”, from a Holding Register?
    3 – Is there a more detailed technical manual for your software?

    Thank you in advance for your help.

    1. I suppose, encode time to Unix time. This is a 32 bit integer.
    2. Yes. Create new calculated channels and use GetBit function
    3. The web manual and this forum.

    The above are the general ideas. We can discuss them in details.


    Hi Mikhail,

    I will try, if necessary I will contact again.

    Thank you
