Media Switcing Hu Cordsets Ethernet systems are predominately designed in a star topology using twisted pair copper cable and/or fiber optic cable. Twisted pair cables either field terminate, usually to a punchdown block, or utilie an - or a Micro-Change M connector. A variety of connectors exist forfiber optic cabling including SC, ST and MT- versions. Ethernet uses a star topology, requiring a message to be sent through a central device. A switching hub is a islayer ll device which connects to an Ethernet station, stores the transmitted message, then forwards it out the appropriate port. Input and output connections from the blocks to devices like sensors or valves are made with industry standard mm Micro-ChangeDC style connections. Server/Firewall Fier Otic Cale As the network requirements of a factory, particularly one used to trans- mit time critical control data, are different than those of the front office, it is often desirable to have all factory communications be linked to their own server. This form of network design not only assists in minimiing front office transmissions from using up factory floor bandwidth, but provides a security function which regulates access to sensitive data and functions. Transmits data by means of light pulses emitted from a laser or LED. This method provides for longer transmission distances km and the ability to support higher transmission speeds. Because of this capability, fiber is pop- ular for use as a backbone cable connecting various network segments. Cordsets are available with several types of connectors including ST, SC and MT-. Twisted Pair Cale/Cordsets Copper based cable, using or twisted pairs. Several different types of cable are available including Shielded STP or nshielded TP, as well Solid Core or Stranded. The cable can either be field terminated to a receptacle via a punchdown block, or can come with - or Micro- Change M connectors often referred to as a patch cable.
