Network equipment connectivity: Equipment Definition Files provide an easy way for creating the drivers for different process equipment.

Arbitration: The SES arbitrates read and write access among its clients to ensure that they can safely access the equipment without interfering with each other.

Security: The SES implements the three levels of client access to two types of variables: read-only variables and read/write variables

The SES web-based Administration enables an operator to easily setup and administer the SES network locally and remotely.

Host communications package includes:

• Pass-Through enables SES to pass the information  between the equipment and the host without intervention.

• SECS-I <-> HSMS protocol conversion

ActiveX and Java network client interfaces enable direct access to equipment variables through the set of objects over TCP/IP, hiding details of SECS protocol from application developers.

Events, Alarms, Traces:  Events and alarms signal to the client that something of interest (such as abnormal condition) has happened in the equipment. The trace reports regularly deliver the values of specific variables requested by remote clients in a  time-stamped packet.
