A documented Commissioning approach offers traceable verification, and ensures a systematic approach that minimizes commissioning oversights. This way you will spot a device who's configuration is bring down the network. Commissioning should always be a closed loop system, the start up tech returning to engineering a detailed commissioning report to include field changes so future design and commissioning can be improved upon. Use a defense-in-depth security approach at multiple application layers, such as physical, device, network, and application, using and enforcing an industrial security policy.
Manufacturing and production data transmitted outside the physical location of facility like with IoT is more vulnerable. Make sure the risk is worth the reward by disregarding toughed advantages that could be obtained internal network. When equipment is linked to outside world, application-specific firewall settings network traffic monitoring should be done, as well ad regular security and port scan sweeps. ControlNet and other industrial network types are more secure networks than Ethernet.

In the RS configuration, set baud rate as high as possible, if communication issues, drop baud rate down.
Potentially bringing data collection, configuration, diagnostics, discrete, process, batch, safety, time synchronization, drive, motion, energy management, voice, and video on to one network for easy access.
See the PLC security section 7. So always be thoroughly trained in industrial network security. In modern PLCs, there are so many options for communication available that it can be hard to decide which one to use. Each communication option has advantages and disadvantages, as well as a unique way of working.
S7 Communication is a popular way to communicate between PLCs because it is a single-sided communication protocol. That means that you only have to program the communication in one PLC. This means that you can read and write data from memory areas, data blocks, input areas, and output areas of a partner PLC. Convenient, but potentially dangerous too. Once S7 Communication is enabled in a CPU, there is no way to block communication with a partner device.
How does OPC work? I hope you like this article about PLC communication protocols. If you have any questions then please comment down below. Each comment matters for us and gives us the motivation to share more knowledge with you all. Thanks for reading! Save my name, email, and website in this browser for the next time I comment. How are you? This is a serial port that is used for half-duplex and full-duplex communication.
This has 9 pins and it is mostly used to do communication with the PLC. This is a serial communication so the data transmission speed is low. By this, we would get a physical link between all the devices and it would give proper data exchange management. By using this we can do high-speed data -communications. Each module would have an extension of both the input and the outputs. The extension modules would have the input and outputs of a different nature from those on the PLC controller.
In parallel communication, all the bits in a word are transferred simultaneously transmitted along with the parallel cables.
