Connecting the Data Cables for Multicluster Communication


Qualified person

In a multicluster system, the masters of the various clusters communicate with each other (see Multicluster-Box documentation). An SI‑SYSCAN.BGx communication interface must be installed in each master when using a Multicluster-Box. If the Sunny Island was ordered with the Communication for multicluster system order option, SI‑SYSCAN.BGx is installed in each master.

Cable requirements:

  • Classification: CAT5e

  • Maximum cable length: 30 m

Procedure:

  1. Ensure that the communication interface SI-SYSCAN.BGx is installed in each master (see SI-SYSCAN-NR documentation).
  2. Remove the terminator from the SysCanOut pin connector on the master of the main cluster and plug it into the SysCanIn pin connector.
  3. Plug the yellow data cable into the SysCanOut pin connector on the main cluster master Connecting the Data Cable).
  4. Plug the other end of the yellow data cable into the SysCanIn pin connector on the master of the extension cluster 1.
  5. Connect the other extension clusters with each other as described in steps 3 and 4. Remove the terminators for this.
  6. Leave the terminator plugged into the unused SysCanOut pin connector. This terminates the communication bus.
