General functions of PLC library

• Sending data values to the cloud server via Internet according to individual cycle or on-change; • Sending messages in a text format or with predefined codes; • Receiving and saving data values from the cloud server; • Storing data values with timestamps (2 stamps: PLC time and server time); • Explicit blocking/unblocking data saving mode for safety reasons; • Encrypted data exchange with a registered server; • Object oriented interface for PLC applications.

PLCcloud security

Security is a priority feature in PLCcloud. Nobody can change or even watch a customer’s data. A PLC communicates only with a known server via protected channel with a dynamic secure code. • Only a PLC initiates commu- nications with a known server exclusively; • Access via login-password; • User groups access levels; • Detailed logging; • HTTPS protocol for communi- cations; • Encrypted channel according to standard AES 256 with unique PLC keys and session keys.

Conclusions

• PLC has completed a full develop- ment cycle from automation of individual machines to factory automation. Now is the time for the next step - business automation. This can only be achieved through integration of the PLC world with IT and the Internet of Things (IoT). • Modern IEC programming system consist of more than just IEC editors with a code translator. Customers vote for one or another IEC program- ming system thanks to rich development, debugging, testing, • communication, integration and visualisation functions. PLCcloud is the next logical development stage. PLCcloud improves not only operations, but also developing and servicing. That is a unique feature of our cloud and it is made possible due to integration with a program- ming system. PLCcloud is a proven technology, tested by more than 200 practical applications with potential for many others in the future.
