Overview HMI and scada systems

The aim of this page is to give an overview about the possibilities for a user dialogue around our PLC's, for the details there are links to the relevant product pages.

7-segment displays

• General

  Our solution

  Products: Classic/PG5

  Products: xx7/Step7

  Restrictions

• To display numeric values there are simple terminals that can be controlled by normal digital outputs

  Compact terminals with bright LED display

  PCD7.D120

  PCD7.D120

  Display only, refresh rate depends on the used output cards

Graftec/Graph and instruction list programming with non-intelligent terminals

• General

   

   

   

  Our solution

  Products: Classic/PG5

  Products: xx7/Step7

   

  Restrictions

• Before we introduced more comfortable tools like the HeaVAC dialogue or the HMI-Editor, this was the only solution to use the non-intelligent terminals together with the PLC's. Nowadays we don't recommend to create new projects with that philosophy, since the creation of a dialogue is very time consuming and excellent programming skills are required. The only advantage is the full flexibility.

  Standard instructions in all PLC's

  PG5, non-intelligent terminals PCD7.D16x, PCD7.D170, PCD7.D202, PCD7.D23x, PCD7.D250

  Possible with Step7, but as the price difference is very small, usually an intelligent terminal is the more attractive solution, non-intelligent terminals PCD7.D16x, PCD7.D170, PCD7.D202, PCD7.D23x, PCD7.D250

  Time consuming, profound programming skills required, the code for the dialogue creates a significant CPU load

HeaVAC dialogue with non-intelligent terminals

• General

   

   

  Products: Classic/PG5

  Products: xx7/Step7

  Restrictions

• Part of the HeaVAC library with predefined elements. Not recommended for new applications, replaced by the HMI-Editor and its HeaVAC Objects. The relevant FBoxes are still contained in the library, so it is possible to modify or extend existing applications

  HeaVAC Library as mentioned above, non-intelligent terminals PCD7.D16x, PCD7.D170, PCD7.D202

  Not available

  The HeaVAC library is required, flexible but not comfortable

HMI-Editor and non-intelligent terminals

• General

   

   

   

  Products: Classic/PG5

   

  Products: xx7/Step7

  Restrictions

• The HMI-Editor is an add-on tool for PG5 and is distributed together with all PG5 packages. It allows to create dialogues for our non-intelligent terminals. The main advantage is the integration in PG5 (for instance resource handling) and the fact that the whole code and texts for the dialogue are stored in the PLC, which means it can be maintaned like another part of the PLC application, via Ethernet, Modem....

  HMI-Editor as mentioned above, non-intelligent terminals PCD7.D16x, PCD7.D170, PCD7.D202, PCD7.D23x, PCD7.D250, PCD7.D79x

  Not available

  The code created by the HMI-Editor creates a CPU charge, that is much bigger than a solution with an intelligent terminal or a PC-based scada system. The structure of the dialogue is given, the programmer is less flexible than with the other solutions

Intelligent terminals

  Our solution

   

  Products: Classic/PG5

  Products: xx7/Step7

  Restrictions

• PC based software tools are used to configure the user dialogue. The tools are very easy to use and the philosophy of the dialogue can be adapted to the user or the application. Touchscreen terminals allow to create easy to use dialogues and are appreciated by the programmers and users. Terminals with different numbers of function keys are available as well

  Windows based software tool with user interface, complete range of terminals, manuals and online-help files in five languages

  Terminals PCD7.D7xx, software PCD8.D81W 

  Terminals PCD7.D7xx, software PCD8.D81W

  When a lot of trend or history functions are required, a PC-based solution is more appropriate

PC-based scada systems

• General

   

   

   

  Our solution

  Products: Classic/PG5

  Products: xx7/Step7

  Restrictions

• These tools allow to create complex but still userfriendly applications. Whenever a lot of datalogging and trending has to be done, a PC-based system is the best choice. Due to the versatility and complexity of the tools, some days of training are required before the first project. Quite a few scada system manufacturers have got an S-Bus driver available. Any scada system containing an OPC client can be used together with our OPC server

  Saia®Visi.Plus is a powerful and flexible tool, that is well integrated in the PCD Classic world

  Saia®Visi.Plus as mentioned above

  We don't have an own product, the standard products of the Siemens world can be used

  Saia®Visi.Plus is for Windows NT4, Win2k and XP only
