Thread: CEL and AML filter restricitons

  1. #1

    Default CEL and AML filter restrictions

    Hello colleagues!

    Can you explain restricitons of Variable name (31 symbols) and Identification (39 symbols) fields of CEL/AML filter?
    Why not to do them according to maximum length of Variable name and Identification of variable (approx. 127 symbols)?

    Hi,

    I assume that these filters are mainly used in combination with wildcards (e.g. machine1.variables.*).
    Do you really need so many characters in your filter strings?

    I do not know the reason, but I could check with the development.

    Regards,
    Bernhard

    Hi, Bernhard.

    Yes, we really need so many characters.
    In some projects we use virtual columns by splitting Identificaiton by symbols position. So filters like Screen1??????????Tank2?????????????????Valve3*
    are widely used (of course, this ?? sequences are formed programmable by VBA).
    And any length restrictions with such filters usage look little strange..

    Also we often use long var names divided into object name and variable postfixes (like ...MOTOR1.FB_ON, ...MOTOR1.FB_OFF, and so on. Due to your restrictions we cannot use wildcards to select all variables for this object like ...MOTOR1.*
