The network can utilize different and mixed link implementations such as Fast Ethernet and PPP. It provides for full redundancy, in order to achieve high network availability. The AC 800M controller is always connected to the Control Network via an STP (Shielded Twisted Pair) cable. Should the local environment be of an industrial nature, the AC 800M / Control Network connection must be converted over to a Fiber Optic (FO) cable. This is achieved by installing an Ethernet Switch having both optical and electrical ports. See Figure 53 on page 153. For more information on Control Network, see Control Network documentation. Communication Possibilities The processor unit (PM8XX/TP830 or PM891) contains the following communication ports, offering the following functions: • CN1 and CN2 are used for connection to the Control Network. Both are RJ45 ports for Ethernet (IEEE802.3) and connection is normally achieved using category 5 shielded twisted pair cable (STP class 5). However, as mentioned previously, within industrial environments it is recommended that all STP cables are converted to optical fiber. – For single or redundant CPUs and single networks: All CN1 ports are connected to the network (CN2 can be used, but requires reconfiguration of the communication set-up for the concerned CPU). – For single or redundant CPUs and redundant networks: All CN1 ports are connected to the primary network and all CN2 ports to the secondary network. Details on cable selection, switches and so forth, are provided in Appendix C, Recommended Components

COM3 is an RJ45 port for RS-232C with modem signals. Examples of protocols are Modbus, Siemens 3964R, COMLI or custom-design. For more details, see protocol-specific documentation. • COM4 is an RJ45 port for connection of service tools (see Connecting Control Builder on page 152). The port has no modem signals. By adding communication interfaces to the CEX-Bus, the number of protocols and processor unit ports can be expanded. The available CEX-Bus interface quantities are shown in Table 19 on page 156.
