    TIWAY I is an industrial Local Area Network (LAN) designed to satisfy today’s factory and plant requirements for data acquisition and control of manufacturing processes. It is a significant enhancement of the Siemens “Local Line,” which supports the PM550 Programmable Controllers (P/Cs) and DS 990 computer products.

    THE TI505 NIM The TI505 NIM is the TIWAY I Network Interface Module for the SIMATIC TI505 Programmable Controllers. See Chapter 3 for a specific listing of controllers supported by the TI505 NIM. The TI505 NIM provides several features which ensure maximum network signal integrity.
  • Page 16 The TI505 NIM provides redundant TIWAY I communication ports. Each of the following models supports a specific type of network communication media. The RS-232-C/423 media interface is configured as Data Terminal Equipment (DTE) and is used to connect the NIM to Data Communication Equipment (DCE) for operation with modems.

  • Page 17: Nim Simplified Block Diagram

    Figure 2 is a simplified block diagram of the TI505 NIM. The media interface blocks are intentionally left unlabeled because the type of media interface depends on which NIM model you are using. The blocks are described as follows. Special Function Interface Controller (SFIC) — delivers and receives P/C com- munications.

  • Page 33: Local Line Biasing

    2.4.1 Biasing Configurations It is very likely that you will have a mixture of TI505, SIMATIC TI500, and PM550 P/Cs on your network. Three different Local Line media biasing combinations exist, based on the number and type of interface devices used with the P/Cs. Possible combinations are Installations consisting solely of self-biased devices.

  • Page 34: Networks With Only Self-Biased Devices

    This configuration exists when only one TIWAY I Device on the Local Line has the Bias Switch, and all other devices are self-biasing. The position of the switch-biased device on the line does not matter, but its Bias Switch must be on. TIWAY 1 Ti505 NIM User Manual Network Design Considerations 2-17...

    INSTALLING THE NIM To place a NIM into your TI505 system, you have to select the NIM communication parameters, install the NIM in the TI505 I/O base, connect the communication cables to the NIM, and initialize the system for operation. The Programmable Controller (P/C) and the programming device should be in place before you install a NIM.

    SETTING THE DIPSWITCHES As Figure 1 illustrates, there are two blocks of dipswitches on the TI505 NIM. The block of eight switches is the NIM Network Address Selection switch.

    Network cabling should already be in place before NIM installation is begun. There are two communication ports on the TI505 NIM. The top port is port A, and the bottom port is port B. Plug the network interface cables into one of these two ports. For media redundancy, use both ports.

  • Page 104: Appendix A Pm550 Cim Requirements

    The CIM is provided with a jumper which allows selection of bias or no bias. The Siemens’ Local Line must be properly terminated at both ends of the trunk to prevent a possible impedance mismatch that could result in signal reflections back along the line.
