    The rung you show is disabled, then is not asigned preset to T0

    Version 1.28.34 does not change date modified. I also expect that any file just opened without any modification saved, is not changed its modified date.

    Right click on desired jump condition, then Clear jump option

    I just realized that npn/pnp field exists. I never had to change it before. Is it really relevant or just to visual indication?

    Note that initialize resets all memory to zero and if you have set some important values like PID parameters they will be all deleted. I find it useful only in new projects downloaded to used PLC.

    I don´t think it works for 400 Hz. Physical inputs requiere a minimum on-time to cath ON state. I implemented your idea long time ago but my frequency was a bit lower.
  7. Gabriel Franco
    It is not possible. You must contact the programmer to get a copy.
  8. Gabriel Franco
    You must set the frequency (MI1) according with your actuator capabilities and the IO specs. https://myzone-kza3sadj.netdna-ssl.com/wp-content/uploads/2015/12/IO-D16A3-TO16_TECH-SPEC_03-09.pdf

    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
  13. 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
  16. Gabriel Franco
    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.
  19. Gabriel Franco
    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)
  21. Gabriel Franco
    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.
  23. Gabriel Franco
    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.
