7.4 Update from F 865. to F 865.X
When F 865. central modules are updated to F 865.X, also the fan conception must be mo-
dified:
Former fan concept:
Z 6012: one integrated fan with fan run monitoring and fuse monitoring
New fan concept:
Z 6018: fan run monitoring for 4 fans and fuse monitoring
K 9212: fan unit (4 fan units for H41, 3 fan units for H51).
See also data sheets of the assembly kits.
7.5 Replacement of F 865.A by F 865.X
F 865.A central modules can be replaced by F 865.X modules after changing to the new fan
concept and using the unaltered user program, but with the new operating system (BS41q/51q
V7.0-8).
7.6 Use of Coprocessor and Communication Modules
System H41q
To the right of each central module one coprocessor module (F 8621A) or one communication
module (Ethernet: F 8627/F 8627X, Profibus-DP: F 8628/F 8628X) can be installed. If they are
operated in redundant mode, the same type has to be used.
System H51q
To the right of each central module up to three coprocessor modules or up to five communica-
tion modules can be installed additionally.
Restrictions
Coprocessor modules:
Max. 3 for each central module, only the slots reserved for the coprocessor modules can be
used (slots 10, 11, 12 or 17, 18, 19).
Ethernet or Profibus-DP communication modules:
Max. 5 for each central module, each of the five slots right of the central modules can be used
(slots 10, 11, 12, 13, 14 or 17, 18, 19, 20, 21). The different types can be mixed.
If they are operated in redundant mode, the redundant coprocessor or communication mod-
ules must be installed in the according slots.
