The document provides instructions for configuring an industrial network interface unit (NIU) by changing the data source to control, setting the IP address using a utility, creating a target configuration with the required modules and IP address, downloading the configuration to the NIU, mapping variables to hardware, downloading a ladder logic project, and adding graphics elements to a toolchest.
35. Drag and drop all elements over the graphic in our toolchest
36. When we bring in a linked copy we are prompted for a name of our existing logic with which to associate it
37. Each tank is completely independent of the others
38.

Up until now all of our logic and graphics have been referenced to INTERNAL variables which is great for testing and commisioning but not much use for the REAL world
We have changed the data source to Control but as yet have not specified the Control driver
In the navigator window we select the control I/O driver icon
As you can see we haven’t selected the I/O type as yet so you can develop the whole project with timers counters and PID loops etc and THEN select which manufacturers I/O you will use. We are using ethernet I/O
Double click the newly created ethernet I/O driver. You will see the current default properties
In the inspector window we can configure our I/O setup. Node number is ok, 2 slots, and change the address to match our network
Select the slot and in the inspector window and the in the dropdown box select the module
And again for slot 2. This configuration will be stored to our Logic controller on the PC
We will temporarily set an IP address to enable our configuration to be stored to the NIU
We need to enter the mac address and the required IP address
It is all straight forward and is simply a tool that negates the need to know about TELNET and ARP commands
Right click on the main rack icon
There are one or two settings in the etherenet interface that need to put in correctly to enable save and download
Enter the IP address
Enter subnet mask these setting must match your network settings on your PC
Set the produced and consumed exchanges to one
After these are set the red crosses should disappear. We can now download. After downloading power cycle the NIU
To map variables we simply drag from the variable inspector window onto the I/O map if you make an error right click and select unmap
To add a bit more functionality we will add an up down counter CTUD you will as ever find all the information on how this works in the help simply by pressing F1 with CTUD element on the logic panel or by selcting help in the companion window or going to the help index
After making these changes to the original element drop it in the toolbox directly onto the ladder element
Download the project
Download progress, warnings and errors shown the feedback zone
You can now see our linked elements have been updated also. If we have a specific need for one switch to be attached to the same logic part in all of our linked objects we can use the universal variable this is denoted by the $ sign. You might want to include for instance an emergency stop button that applies to all circuits
Let’s add some more graphics to represent our up down counter. Select the Home panel You can get graphics from the Machine Edition supplemental disk or from your own libraries to achieve aesthetically pleasing graphics we need to combine .bmps jpegs etc.. With ME animated objects. I have saved several parts to my toolchest
The quick way is to drag and drop the parts on the panel
Some appear a little odd but we can deal with that in a moment
The motor pump graphic is showing a navy border to get rid of this simply go to the properties inspector window and set transparency to true and click on navy now all navy coloured parts will be transparent
By dragging and resizing we can quickly mate up our individual parts send to back and front are useful to get the appearance just right There is a quick test feature that enables us to see how our panel will look without the need to download the complete project
By duplicating the pipework I have ready made parts that just need placing I have added a round rectangle, even this has an entry in the help system, to the tank to show fill level
By double clicking the round rectangle we can assign a variable through the animation properties window. Here I have assigned tank.cv which is the current value of the CTUD element. Here we set from 0% to 100% is equivalent to 0 to 3000 which is the counter preset in our logic
Having completed our tank system we will place in the toolchest alongside our start stop panel directly over class name
We now have original on the panel and we can in a similar way to the logic duplication bring in two linked copies which we will assign the offered structure names
Now we can see each tank and start stop panel operating independently here Tank one is on and rising
Tanks 1 and 2
Finally Tanks 1,2 and 3 all running with linked logic and graphics but totally independent
