Operational Differences vs. Genius Bus Controller
Persons migrating from a Genius environment where the Genius Bus Controller performs
functions similar to those of the GCG001 will want to be aware of the following differences:
1.
COMMREQ function block SYSID and Task parameters change. SYSID is now the rack &
slot of the PNC connected to the GCG001. Task is now 132.
2.
COMMREQ data blocks are different, mainly due to added PROFINET Device Number and
expansion of memory address fields from one word to two words. See COMMREQ
summary in Section 6.3.3.
3.
Pulse Test and Assign Monitor COMMREQs do not support Genius bus address of 255 to
send messages to all blocks.
4.
COMMREQ commands: GCG001 does not support all datagrams. See section 6.3.2 for a
corresponding list of supported COMMREQs.
5.
GCG001 supports hot-standby and duplex redundancy modes only. No support for dual-
bus redundancy.
6.
GCG001 can be assigned to bus addresses 30 and 31 only.
7.
GCG001 does not support Field Control, GENI, GENA, or PCIM.
8.
Prior to V2.0.0, GCG001 did not support 76.8K and 38.4K baud rates. Beginning with
V2.0.0, all Genius baud rates are supported.
9.
Prior to V1.1.1, fault contact operation has changed. Whenever there is a fault on a single
channel of a Genius block, all fault contacts associated with that Genius block will
become active. All faults on that device must be cleared before any of the fault contacts
will de-energize. Beginning with V1.1.1, when there is a fault on a single channel, none of
the fault contacts will become active.
10.
Genius faults routed through a GCG001 appear as PROFINET faults to the CPU. The same
fault routed through a Genius Bus Controller will present a different error code.
11.
Prior to V1.1.1, when a Genius block encounters a circuit fault on one or more points or
channels, the GCG001 causes all of the input references associated with that block to
either hold last state or go to default values until such time as the fault is cleared. See the
Alarms discussion in section 4.1.4 for a work-around to this behavior. However, beginning
with V1.1.1, when a Genius block encounters a circuit fault on one or more points or
channels, the GCG will cause only the faulted input references to hold the last state or go
to default values. The other points or channels on the block will continue to operate
normally.
