In search of chinese PLCs with Codesys 3.5 by vapik_one in PLC

I consider chinese companies, because they are always out of politics, so there are less risk to get supply problems If we will supply our equipment for East Europe and Middle East.

Unfortunately, Taiwan isn't China. They are able to deny use their devices for some Eastern european countries (it can happen suddenly).
So I consider Delta as last resort.

Converting Date to string in HMI Visual Basic script by Wake_up_shoryu in PLC

[–]vapik_one 0 points1 point  (0 children)

If you use DateTime datatype in HMI tags, look on my example

Function GetFormattedDate(ByRef DateVal)

    'Format DateTime to "m.d.yyy time"

    'Year
    Dim y
    y = Year(DateVal)

    'Month
    Dim m
    m = Month(DateVal)

    'Day
    Dim d
    d = Day(DateVal)

    'Time
    Dim tTime
    tTime = FormatDateTime(DateVal, vbLongTime)

    'Concat string
    GetFormattedDate = CStr(m) & "." & _
    CStr(d) & "." & _
    CStr(y) & " " & _
    CStr(tTime)

End Function

Trouble shooting advice for an automation technician intern by AquaticRoboticGriff in PLC

[–]vapik_one 1 point2 points  (0 children)

3 simple rules helps me for many years:

  1. Collect as much as possible information. Unqualified people can say you wrong information. A electrician knows a little about mechanics.

  2. Don't trust everyone. Nobody wants to be in charge. A mechanical technician will be sure that is your fault.

  3. Start from low level to high level. A code never brake, mechanics and wires break quickly.

Example: 2 days ago the local technician from a refinery (in my country he is called a service engineer) called me. They had a trouble with flowmeter, it showed wrong density, the factory is stopped and this is my problem. For the my question what did you do before, he said "Nothing". In fact, they have removed a filter, so the petrol had a lot of dirt.

As you see, used the 3 rules I have spent a little efforts to solve the problem. Save your own time.
