Assuming that Concept programming package is installed and a shortcut is on the desktop, click on Concept DFB icon. Next click on Project select Variable declarations on the drop down.

The variable dialog box will appear. This step allows the programmer to define inputs and outputs of the function block. The function block is only accessed through the input and output pins. In that respect the user defined block is like an integrated circuit. The inner workings of the block are hidden from the rest of the PLC program.

The block can be thought of as a new PLC instruction. Click the input radio button and enter the variables shown in illustration 3. The SetPt is the first input and it represents the desired value for the process variable or second input to the block. The second input variable PrcVar represents the measured value of the quantity that we are trying to control. This function block uses the REAL data type for all inputs and outputs.

There are many types available and it is possible to create compound data types made of more than one type. Two additional input variables are shown: FeedBk1 and FeedBk2. These represent feedback quantities. I will defer a discussion of these until a later article where their purpose will be made clear. In fig.

In this box we enter a single variable ProcErr. This variable will represents the difference between Setpt and PrcVar speed or the system error. Click on the OK button at the bottom of the viable dialog box to close the box. Next click on the project drill down icon, as shown by the upper pointer on fig. The drill down will appear without any sections or groups defined.

Right click on the top item in the drill down named Project and the New section dialog box will appear. Type in the name of SummingJct. The code type defaults to FBD of function block. One could also select on of the other types of coding as well but we are programming in FDB in this article. New Group , if selected, creates a folder like object which can contain more than one section of related code.

To create a section within a group click on the group icon just left of the group name. Our function block is simple and only requires a single section. Click OK to close the dialog box.

This sheet is like a CAD drawing. Using the icon on the tool bar, one can create a network of function blocks that resemble electronic drawings. With this blank sheet we will need to place some arithmetic predefined function blocks to process inputs and assign an output.

While on the block selection box the cursor will be the normal arrow. Moving off the box will cause the cursor to change to what is shown in fig. Finally, there are six buttons on the bottom of the dialog box: Library There are quite a few libraries to select more specialized blocks but it is beyond the scope of this article to discuss these.

DFB allows selection of user defined function blocks such as we are creating in this article. The others are self explanatory. Moving the cursor to the worksheet will cause the pointer to change to the cross hair and function block icon. Left clicking on the worksheet will drop the selected block on to the sheet at the location of the cross hair. Press ESC to return the cursor to a pointing device instead of a function dropping device mode.

We are now in position to assign inputs and output variable previously defined to the function block pins. This is indicated by the black square on the bottom of the block. Placing the cursor on the black square and dragging down will reveal more inputs. Add two more inputs. User Defined Blocks in general do ot have the ability to have expanded inputs because there is no way to express this in the limited programing tool set provided.

This click will open a dialog box allowing you to select from the available input variables previous defined. Shown in fig. Chose ProcErr by double clicking it. Notice that clicking on an output pin only shows one variable. This variable was the only variable we previously defined as an output. We are nearly done assigning variables. The function block programming allows outputs to be assigned to another function block without using intermediate named variables.

This is great because it cuts down on the number of variables needed for a program. Also, note that in fig. Hitting the delete key will delete the block. Press Ctrl-C and Ctrl-V to copy and paste the block. More than one block can be selected at a time.

Wiring is preserved to and from the clip board. In fact the whole sheet can be selected with Ctrl-A and repasted back to the sheet. The execution order for the blocks on a sheet can be changed this way.

More in later articles about execution order and changing the order. The cursor changes from the arrow to a wide cross hair when the wiring tool is selected. The wide cursor is shown on the above illustration as the upper most cross hair.

The wide cross hair changes to a thin cross hair when the cursor is moved to a suitable function block pin. The check mark also indicates the cursor is over a suitable pin. See Fig. To connect or wire pins together, one can click the first pin and either hold down the left mouse button and drag the cursor to the next pin or left click the first pin and move the cross hair to the next pin and left click.

The outputs of an output pin can be connected to multiple inputs of other function blocks. There is no fan out limit. The pins must have the same type in order to make a connection, e. The summation and subtraction process is common in a process controller. I will use this block in two different ways in the final composition of a turbine speed control. The sumjct block is generic in nature so that it can be used in various parts of our turbine governor. The function it performs is comparing the Process set point to the Process controlled variable and outputting the difference.

The process controlled variable value can be modified by one or both feed back inputs. Join Us! By joining you are opting in to receive e-mail.

My site is shortly going to receive a Modicon PLC incorporated within a larger system. I'm likely to be the first port of call on this system, although I'm not familiar with this model of PLC.

Does anyone have any opinions, good or bad, about the Schneider product? Any known weaknesses or common faults I'm going to meet? All comments warmly received. The Quantum plc scans the logic differently than most plc mfg's.

Jeez, just what I need You could be programming and troubleshooting on a whole new level. I am currently updated a plant to the quantum series controller Thanks McGowan and everyboady else who has replied. Hi killemall, Thanks for taking the time to reply.

Many years ago I began programming on Modicon 's with the old dos Modsoft programer. Windows XP. I'm with several others in this thread. I am working in automation business during of 4 years. I have used a long list of PLC's from a long list of manufaturers. Hi Scotty, Welcome to the world of Schneider Thanks for the reply Kevin.

Scotty if you have a laptop around that you can dump and install windows 3. Hi McGowan, Modbus Plus is in use for a touchscreen, the plc also is running an Echelon network interface to a diesel generator control system. On the assumption that I can get hold of Modsoft, can anyone confirm the pin connections of the serial cable to connect a laptop to the PLC? Kevin, Thank you very much. Hi scotty, No prob.
