PCCC (Programmable Controller Communications Commands)

RS-232

An EIA standard that specifies electrical, mechanical, and functional characteristics for serial binary communication circuits.

Security Mask

The Security Mask, when configured, allows you to restrict incoming TCP/IP and/or UDP messages to have source IP addresses that are within some prescribed range. For example, if you wanted to restrict all message sources to be from within a company’s allocated IP address range, a Security Mask could be configured that would block any IP address outside that range.

SMTP (Simple Mail Transfer Protocol)

This protocol defines the interface and commands with the Mail Transfer Agent and defines how the ENI will deliver the outgoing mail.

Single-Hop/ Multi-Hop

Term that refers to how many “different” networks a message must traverse to reach its destination. For the ENI, a single-hop message is one whose source and destination nodes are both TCP/IP end points.

TCP (Transmission Control Protocol)

TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.

TCP/IP (Transmission Control Protocol/Internet Protocol)

The suite of communications protocols used to connect hosts on the Internet. TCP/IP uses several protocols, the two main ones being TCP and IP. TCP/IP is built into the UNIX operating system and is used by the Internet, making it the de facto standard for transmitting data over networks. Even network operating systems that have their own protocols, such as Netware, also support TCP/IP.

UCMM (Unconnected Message Manager)

The UCMM is an object defined in the CIP protocol. This object is responsible for handling connection requests and unconnected message traffic.
