Micro PLC Hardware Configuration

 Write the steps for Micro PLC hardware configuration for Analog Modules like AI, AO and Digital signal modules like DI, DO.

Micro PLC Hardware Configuration

For this plc configuration, we will use the Simatic manager software. The configuration of the micro PLC can be done by using Profinet I/O system in the Simatic manager.

Load and configure the Profinet GSD file and save it in an appropriate directory. Start the siemens configurator and install a new GSD file in the software.

After configuration and installation, the hardware configuration file will be available in the hardware catalog.

As shown in the below method, we can configure micro PLC in Simatic manager.


For example, we have considered a micro PLC M13C. Open Simatic manager and configure S7-300 PLC in the hardware configuration. For micro PLC, take Profinet I/O supported CPU.

As shown in below figure 1, we can configure CPU 314C-2PN/DP in the hardware configurator window. This CPU can be selected from the hardware catalog. Add a Profinet bus in CPU as shown in figure 1.

After adding an ethernet I/O bus micro PLC can be configured on an ethernet bus.

As shown in below figure 2, after the configuration of PLC we can take micro PLC from the hardware catalog.

Select the VIPA micro system folder and select the M13C CPU.

VIPA Micro System

Add Digital input, digital output, analog input and analog output modules in micro PLC.

After the configuration of PLC as shown in figure 1, we can add a signal module in PLC as per requirement.

For example, here we used 1 DI module, 1 DO module,1 AI module, and 1 AO module.

First, click on PLC and search DI module from the catalog and add it as shown in below figure 3.

Right-click on row no 1 to add the module.

DI Module Configuration in Micro PLC

As shown in below figure 4, we can add the DI module (M21) by selecting AI folder, the same procedure for all other modules.
