Click PLCs with Wifi

I see that Click Plus have Wifi available. Can two Clicks talk to each other without a router?

    No, they don't have provisions to act as an AP

    are you wanting to have communication between two machines, dont have enough I/O, need to run a wireless sensor setup, or are you wanting a master slave plc setup?

    This is a machine that has two parts, a carrier that moves bay to bay in a large greenhouse. It moves a Spraycar that it launches into each bay and travels over 200 feet away and returns. I built the machine 20 years ago and it is time to upgrade the controls. Click Plus looked like it might be a good way to do it. I am not a fan of Click PLCs, I've been using Do-More BRX but thought I'd take a look. I find that project cost is more related to programming time than PLC cost. The limited Click instruction set takes more time to program. If you are building lots of the same product then Click makes sense.

    You might be able to use two of these and connect them to the Ethernet port on a BRX you mentioned (Or Click or any other PLC):

    Those create a "wifi bridge" that lets two areas connect on the same network. It would make the BRX's look like they were connected together with a wire. Note that they do use 24v proprietary PoE power, so you cannot just plug them into a normal poe switch. It does say they come with the correct poe injector though

      For 200' the Bullets work well and can be omni directional. Assuming you can find stock.

       

      If needed, Tycon makes DC powered 24VDC passive PoE injectors.

       

      Slight vent about Ubiquiti (among many), sticking to their non-standard 24V passive PoE on airMAX while simultaneously discontinuing its availability on any Unifi switch other than a full 1U rack mount.

        I've done this before using some inexpensive ethernet bridges and it worked
        well. The communications can be very iffy and the system still works well as
        there isn't any sharing of critical stuff like positions or limit switches.
        That was about 15 years ago and I was hoping there were better solutions at
        low cost now. I appreciate your suggestions. Probably just going to go
        with a router and a bridge, as we want cell phone connectivity via the wifi
        too.
