    48 analog inputs per EX-A2X or EX-RC1, 6 IO-AI8. It is because data bus capacity, not PLC memory, if I remember well (from support answer I got time ago).

    You may also try PID output limits: output low limit = -1000, output high limit = +1000, then scale PID output to your analog output.

    No problem at all, either

    I have mixed different protocols in different sockets without any problem
  5. Gabriel Franco
    I use UDP instead of TCP set as protocol in a single socket init. With UDP there is not need of connect/disconnect everytime I change to the next slave query. Query first slave, wait for its response, process data, wait a small time, query second slave and so on.

    1. Yes, you can use 3 different sockets, port 502. 2. Try SLAVE ID=255 instead of 1 Don´t forget to Reset MB4 after reading holding registers.

    As far as I know, it is only possible to make data table visible / invisible based on access level. I would use two different data tables overlapping with visibility restrictions and Read-only box checked / unchecked

    I suggest you get a MODBUS TCP function to achieve what you want

    Go to HMI ... Font Handler menu. Then select the font you want add special characters (defaul fonts cannot be modified) and select those required characters

    Use PWM function, using PID output as input for PWM block.

    Version 1.26.90 does not have such an option. Would be nice to have it.

    I would use surge protection devices, both sides: 110 V and 24 V; good isolation relays (with AC snubber or DC diodes)

    Use any bit (MB or XB) you want, in parallel with SB2. Don't forget to Reset the bit. This way, there is no need to restart PLC .

    I think it only works for Vision family, not Unistream.

    Yoy can save it as UTC (double word, seconds from 01/01/1900) and then in Excel convert it to date/time format.

    Use address 8 and 9 to read Net weight high and low bytes. Tags should be INT16.

    I don´t think WebServer are the best way to inform alarms. From my point of view, WebServer are not HMI extension. If you need to remotely inform alarms, you could send SMS.

    Update firmware before first program download
  19. Gabriel Franco
    Try User Access Control, a more powerful tool for your need

    I suspect you´re using a CT with AC volts output. Analog input is only DC, 0 ... 10 Vdc range, then you need a converter from AC Volt to DC Volt.

    In ladder, use RESET COIL to reset the bit you use in HMI button
  22. Gabriel Franco
    I suggest to split code in two separated rungs: first, to read row and second to SET MB 0 (You´re using contact instead of coil) and load HMI. Make sure you´re not using ML 1 in other place and variable in HMI is large enough to show all characters.

    I had same problem long time ago. Workaround was, to increase delay time between reading different devices when an offline device detected.
  24. Gabriel Franco
    Go to "HMI - Font Handler" menu, select the font you want to modify and select those characters you want to show (only not default fonts)
  25. Gabriel Franco
    Regardless of the default socket and port configuration, I always configure the values at power up. It makes that rung explain itself and avoid misunderstandings with other programmers or even myself over time
