sensitivity scale factor respective to full scale setting provided in datasheet Select SDA and SCL pins for I2C communication With this demo, it's just start point & it can be come true with acceptable sampling time.

Or we can use it as portable analysis device for prevented maintenance. For example with high power motor, it can be attached on gearbox and take 6DOF vibration data for analysis or popup alarm to PLC system when vibration is higher than limit.

From beginning of this project, my purpose is making a vibration sensor that can be integrated to industrial network, something like: will be very cheap & useful for vibration protect or vibration analysis.

* Jobs for reading/writing the registers.

* Retrieving the status bits STS_EN, STS_STRT and STS_DO.

* Starting/stopping via software gate SW_EN.

To control pulse width modulation via the user program, we use SFB 49 "PULSE".

This demo is based on integrated PWM function in CPU314C-2DP.

NodeMCU + MPU6050 are connected to PLC system by wifi router and it took roll value from MPU6050 to adjust direction & speed of DC motor.

I had to do like that because I didn't have motor DC drive connecting with PLC.

As picture above, 24VDC PLC outputs are connected to " 24V to 5V Converter Board" to change voltage level and then control DC motor through L298N with PWM integrated function inside PLC 314C-2DP.

Wireless router is located inside my home with distance about 15m and it is not shown on the picture.

Change DB1 values by Arduino program and check the PLC's DB1 online monitoring.

The “WriteDemo” program writes the desired value from Arduino to the DB1.DBB0 & DB1.DBB1 being stored in the PLC.

In PLC, we created DB1 (Data Block) containing 1,090 bytes with KNOW_HOW_PROTECT (generally speaking, this DB is locked in Siemens terminology).

Enable Security Level 3 (Read / Write Protection) in the CPU300 configuration – Then, Compile & Download to Module.

Write to PLC’s Data Block at Security Level 3

While Arduino reading DB2 from the PLC, I used "FORCE" function to change value of two bytes DB2.DBB0 & DB2.DBB1 to check whether Arduino is reading correctly or not.ģ.2.

The “DBGetDemo” read 100 bytes values from DB2 and displayed them on the Serial Monitor of Arduino IDE.

In PLC program, I created DB2 containing 100 bytes with initial values assigned in order from 0 ~ 99.

Arduino read DB values from PLC - “DBGetDemo” I was tested in the case of S7-300 CPU + CP343.ģ.1. ) or via a separated Ethernet card (like CP343 for CPU S7-300), or CP443 for CPU S7-400). Settimino can directly access the Siemens PLCs with built-in Ethernet moldule (such as CPU 315-2PN/DP, CPU412-2PN/DP, CPU414-3PN/DP. You can also use the SIMATIC WinCC as an HMI / SCADA system to control Siemens S7 ™ PLCs or ARDUINO ™. If you are an automatic engineer, you will be very knowledgeable about it.

I used STEP 7 Professional 2010 V5.5 to configure hardware & write program for PLC. Little Endian: LSB (left-most bit) -> MSB (right-most bit), with same DWORD above but ARDUINO ™ will be stored in the opposite way to PLC.Big –Endian: MSB (left-most bit) -> LSB (right-most bit), for example, DWORD 0x4C21112F is stored in PLC Siemens S7 ™ as follows:.In the manual, please note the terms "Big-Endian" and "Little-Endian" to describe differences in reading and writing data between ARDUINO ™ (Little -Endian) and PLC Siemens S7 ™ ( Big -Endian). You can download the link at: Settimino Library, which includes: library, detailed instructions for using settiminno library and sample programs.
