Schneider/Telemecanique Zelio-Logic smart relay

geov
Hi all,

first post to the new look forum. Does anyone have experience of the above ( the one I need info on is a model which has been superseded).

One of the perameters needs to be changed and I need to know if this can be done directly on the unit itself or if software is required.

Either way I’m going to have to get someone in to do it, as I have no plc experience, but I’d like to know in advance what’s actually involved.

Thanks in advance for any info.

    Their programing leads used to end in a 9 pin rs232 lead, but the newer ones contain  a USB to serial conversion in the plastic bump at the end of the cable.

    Underneath it is still a serial bus device, but not with standard Rs232 voltages-   as this chap shows by opening one up, it is Rs232 framing but at 5V logic levels,

    he mis identifies the opto-couplers as if they are OP-amps.

    lt'd not buy a special lead, but I'm not afraid of a soldering iron., and I think it uses something like  https://uk.rs-online.com/web/p/optocouplers/5473942/

    as the isolators.


    software seems to be downloadable in various versions from here..

      it may be worth downloading and perusing the zelio-soft manuals for differnt code versions, to make sure it is for the right model.

    If you need to daisy chain units with modbus he default parameters 2-wire, RTU, 19,200 baud, even parity, address 1.
    Parameter Options
    wires2 or 4
    Frame format RTU or ASCII
    Transmission speed (baud)1200, 2400, 4800, 9600, 19,200, 28,800, 38,400, 57,600
    ParityNone, even, odd
    Network address1 to 247
