The Profibus on FO basis is preferably used for:
•
Long distance links
•
Links between buildings
•
Installations with high EMI
•
Links close to power cables
•
Areas with high potential differences
•
Large installations
•
Installations where a protective separation by the network is required
•
Cables in narrow cable ducts
•
If cable redundancy requirements have to be met
•
In hazardous areas
Use fiber optic cables wherever this is possible to improve the
operational reliability and achieve optimal EMI shielding.
Always use fiber optic cables for links between buildings. Fiber optic cables provide
for protective voltage separation and ensure lightning protection without requiring
additional measures. Besides the indoor cables already described above, outdoor and
underground cables are also available.
Use multi-wire cable to reduce cable laying cost. As already mentioned for indoor
cable links, multi-wire cables enable additional data links in future. Moreover, you can
change over to an unused wire in case of wire-break.
Several outdoor cable types - e.g. gopher-protected or with a special steel or aramid
reinforcement - are available. Note that steel-reinforced cables should only be used
under special conditions for outdoor applications. In this case, the reinforcement must
be grounded at both ends when entering the buildings to provide lightning protection.
