    5.3.1 I-CR module functions Intercontroller CAN bus extension (one or more I-CR modules can be used). Intercontroller CAN bus bus-tie bridging – makes groups of controllers in segments A and B“invisible” one for another depending on bus-tie breaker state, keeping the PC communication (ILB, IG-IB) in function for all controllers.

    Connection of I-LB+ or other bridging modules Note: If I-LB+ (or other bridging module) is to monitor all the site, it is recommended to place it at the position 1. If there is preferably monitored one group (within one switchboard) and the other controllers not at all or only seldom, option 2 is more suitable.

  • Page 71: I-Cr-R Configuration Jumpers

    Intercontroller CAN bus extension – each I-CR-R module provides also CAN bus extension in the same way as I-CR module, i.e. creates segments of the bus where the length of the line is limited within the segment only, not within the whole system. Note: The redundancy system only makes sense if the cables of Primary and Backup buses are placed physically into different cable routes! Placing them into the same cable route increases the risk of damage of both cables at once.

  • Page 81: Termination Resistors

    6.1.5 Termination Resistors Because each differential pair of wires is a transmission line, you must properly terminate the line to prevent reflections. A common method of terminating a two-wire multidrop RS-485 network is to install terminating resistors at each end of the multidrop network. If you daisy-chained multiple instruments together, you need a terminating resistor at only the first and last instruments.
