pascalscada's Introduction

PascalSCADA 1.0 - A multiplatform SCADA framework for Lazarus

These components allow stabilish communications with Modbus RTU, Modbus TCP, Siemens PLC and Mitsubish Melsec devices in a easy way (this means: without write code), through window controls (buttons, sliders, animations), tags, protocol drivers and port drivers, without lose advanced features that you can implement using code.

This code is a entire rewrite of PascalSCADA hosted at https://sourceforge.net/projects/pascalscada. The main goal of this initiative is:

  1) Fix some design shortcomings of the actual version of PascalSCADA (0.7.3). A example is the low number of tags that can be inserted in a project form in design time. For more then 1000 tags per form or datamodule, you should create tags in runtime, via source code.
  2) Performance, performance and more performance.
  3) Split some interfaces that has more than one function. By example IHMIInterface, that handles security for HMI controls and serves as Tag interface.
  4) Improve the translation, using .PO files instead of language defines;
  5) Improve the project modularization
  6) Extend the security system to all standard controls of Lazarus
  

This code is under modified LGPL (see LICENSE.modifiedLGPL.txt). This means that you can link this library inside your programs for any purpose. Only the included part of the code must remain LGPL.

If you make some improvements to this library, please create a new issue and attach the patch of your changes.

Bug or logical oversight

I am trying to get PascalSCADA to compile with both D7 and Tokyo. Except for the HMI stuff, I have managed the rest to compile.

While doing that, Tokyo highlighted a potential bug, or a logical error in 2 routines.

Namely,

in function TMelsecDriver.DoRead()

        if FRemainingBytes > 0 then begin
          res := PCommPort.IOCommandSync(iocRead, 0, nil, FRemainingBytes, DriverID, 0, @IOResult2, starts, ends);

          if res <> 0 then begin
            IOResult1.BufferToRead := ConcatenateBytes(IOResult1.BufferToRead, IOResult2.BufferToRead);
            IOResult1.Received := IOResult1.Received + IOResult2.Received;
            if IOResult2.ReadIOResult <> iorOK then IOResult1.ReadIOResult := IOResult2.ReadIOResult;
          end else Result := ioDriverError;
        end;
        Result := DecodePkg(IOResult1, values);

shouln't it be

        if FRemainingBytes > 0 then begin
          res := PCommPort.IOCommandSync(iocRead, 0, nil, FRemainingBytes, DriverID, 0, @IOResult2, starts, ends);

          if res <> 0 then begin
            IOResult1.BufferToRead := ConcatenateBytes(IOResult1.BufferToRead, IOResult2.BufferToRead);
            IOResult1.Received := IOResult1.Received + IOResult2.Received;
            if IOResult2.ReadIOResult <> iorOK then IOResult1.ReadIOResult := IOResult2.ReadIOResult;
            Result := DecodePkg(IOResult1, values); <<<---- HERE
          end else Result := ioDriverError;
        end;

similarly

in function TMelsecDriver.DoWrite()

        if FRemainingBytes > 0 then begin
          res := PCommPort.IOCommandSync(iocRead, 0, nil, FRemainingBytes, DriverID, 0, @IOResult2);

          if res <> 0 then begin
            IOResult1.BufferToRead := ConcatenateBytes(IOResult1.BufferToRead, IOResult2.BufferToRead);
            IOResult1.Received := IOResult1.Received + IOResult2.Received;
            if IOResult2.ReadIOResult <> iorOK then IOResult1.ReadIOResult := IOResult2.ReadIOResult;
          end else Result := ioDriverError;
        end;
        Result := DecodePkg(IOResult1, tempValues);
      end else Result := ioEmptyPacket;

shouln't it be

        if FRemainingBytes > 0 then begin
          res := PCommPort.IOCommandSync(iocRead, 0, nil, FRemainingBytes, DriverID, 0, @IOResult2);

          if res <> 0 then begin
            IOResult1.BufferToRead := ConcatenateBytes(IOResult1.BufferToRead, IOResult2.BufferToRead);
            IOResult1.Received := IOResult1.Received + IOResult2.Received;
            if IOResult2.ReadIOResult <> iorOK then IOResult1.ReadIOResult := IOResult2.ReadIOResult;
            Result := DecodePkg(IOResult1, tempValues);  <<<---- HERE
          end else Result := ioDriverError;
        end;
      end else Result := ioEmptyPacket;

LockList/UnLockList

in unit 'pascalscada.protocols.customprotocol.pas'

procedure TpSCADACustomProtocol.TagScanTick;
var
  list: TpSCADAThreadTagAddressInfoList.TpSCADAGenericThreadListType;
  i: Integer;
begin
  if Assigned(FTagList) then begin
    list:=FTagList.LockList;
    try
      {irrelevant code}
    finally
      FTagList.LockList; {<--- this should be UnLockList}
    end;
  end;
end;

Displayed when an exception is encountered

SerialPortDriver1 -> ModBusRTUDriver1 -> PLCTagNumber1 -> HMILabel1 .
It can be work , but when com1 is error , for example : other program use this com1 .
my code is below :
try
SerialPortDriver1.ComPort := cbbComName1.Text
except
on E:Exception do
begin
PLCTagNumber1.AutoRead := False;
PLCTagNumber1.Write(-1);
end;
end;

PLCTagNumber1 always show last number , not 0.0 or -1 ;
why ?

install pascalscada_db. & pascalscada_full error
