Data exchange between different devices is an integral part of process and factory automation, which often creates unplanned headaches for engineers. Fixing communication protocols and ensuring interoperability of equipment is a particularly important task for automation. Even a small inaccuracy in the data can cause significant disruptions in the company's daily life, which in the end can turn out to be a financial loss. This may seem like a funny comparison to you, but the flow of data is as vital to automation equipment as the circulation of blood in arteries to a person.

I will repeat again that for workers to receive a real-time flow of production data, to exchange data between connected systems, and to monitor and control equipment, modern automation is required. When designing equipment from scratch or upgrading existing ones, the mutual adjustment of Modbus RTU and Modbus TCP IP protocols is still an actual challenge for many of us. By delving into the needs of ZTF Lāsma customers, we have found an excellent solution for connecting protocols. This is the Seneca Z-KEY-Gateway
