5.23 X20 redundancy system
Redundant network cabling is often essential to safe operation, especially in processing plants. The potential for
danger, especially to the lines that run through the plant, can be disproportionately high in relation to the need to
keep communication active in all operating situations. Redundant cabling and separate cable routing are effective
ways to help reduce this risk.
POWERLINK cable redundancy is based on the principle of doubling the communication lines as well as providing
continuous and simultaneous monitoring. A mechanism feeds data simultaneously into two cable lines. The same
mechanisms are used to receive this data from the redundant network.
The following modules can be used to set up a POWERLINK network with cable redundancy:
•
X20IF2181-2 interface module
•
X20HB8884 compact link selector
•
X20BC8084 bus controller
