Now you can see the MC80 compact PLC
On the back, the system has been designed to be fixed in a rail din
You can see the terminal, it looks like that
For the wiring, 3 pin terminal block modules are available
The first one with a screw clamp: BMX FTB2010
A caged terminal block BMX FTB2000
and a terminal spring BMX FTB2020
On the front panel of the MC80, we can see an USB port to connect to PC,
a reset button to realize a cold restart,
ethernet link for I/O scanner, a rotary switch for IP address to define the roll name,
serial link and can open link, can open master.
We create a new application, we select the range MC80,
we have the 5 levels, in my example I will use this one with 4 analog input and 2 counters .
I will not define password,
as you can see this is a CPU with Can open
The menu is like M340 PLC and M580.
You can define the max number of objects, the behavior of the CPU, cold restart and etc.
Regarding the logic of the application, we can define MAST tasks,
for each task, you can define the periodic cycles and the length.
We create a Mast section; in this section you have the system bit S6
which is equal to M6 and on the rise edge of M6 I will set the digital output and in the fall edge of M6 I will reset the digital output.
We have to build it and transfer the application inside the PLC as usual,
using USB or ethernet link.
When you are connected to the PLC you can turn around the PLC,
You have the digital module in the middle, in the right side you have analog module and, on the left, there is the counter
We will now create an animation table and from this we will observe the DDT,
so the object which are linked to each module for the digital output module,
for the digital input and for the analog input module.
In our example we see the DDT of the digital output module, we see that the hearth bit is equal to 1 meaning that the coupler is correctly powered with 24V and 0V
Now you can see the discrete input value which is moving to 1to0 every second
because S6 change to 0to1 every second and the logic of the section copy S6 inside the digital output
In connected mode like for the other PLC range you can observe the section of the logic
and you can see that each line moves from red to green according to the value of the digital object.
If you click on an object in the section, you will see the precise naming of the object which match with the Device DT name.
Now we will provide online modifications.
So, you will see that control expert 15 is able to build online application and to apply it on the CPU without stopping it.
Now we perform a build of the application.
So, we put the CPU in stop, we build and transfer the application inside the CPU and at the end we will move the CPU in run.
