ISaGRAF– A Rockwell Automation Company –  announced that its ISaGRAF software is now embedded in CSE-Semaphore’s Kingfisher series of Advanced RTUs, which are now available with Secure DNP3 authentication. This security protocol provides protection between master stations (e.g., control servers,HMIs) and remote stations (e.g., RTUs, PLCs) by verifying that both the master station and remote station are who they claim to be. Authentication ensures that messages arriving at the remote station come from the master station or another legitimate element in the SCADA system. The Keyed Hash Message Authentication Code (HMAC) protocol used in the authentication process validates data integrity by using three components, including a shared key that only the sender and intended recipient have, so that only they calculate or authenticate the HMAC.

Semaphore’s Kingfisher PLUS+ and G30 models both fully embed the ISaGRAF 5 control software environment, making them the first RTUs to support both the IEC 61131-3 and IEC 61499 standards, according to the companies.

Using ISaGRAF 5, a field device manufacturer canlibrary.
