Conformities
The FLOWSIC30 complies with the following specifications:
● HCF_SPEC-127, revision 5.0
● HCF_SPEC-301, revision 6.0
● HCF_SPEC-151, revision 8.0
● HCF_SPEC-99, revision 8.0
● HCF_SPEC-183, revision 13.0
● HCF_SPEC-81, revision 8.0
The device type code of the FLOWSIC30 gas meter is 0xC782 (FieldComm/HART
®
Founda
-
tion registration pending) .
Point to point wiring
The device supports point-to-point connections. A host and/or a field communicator can be
integrated into the bus as communication master(s). Communication may run through Ex
isolators according to the HART
®
specification. Any polling address in the HART
®
address
range can be used to address the device. The polling address must be configured by the
software using the command #6 (default: 0).
Network (Multidrop)
The device can also be integrated into a network. Polling addresses must not be used more
than once in the network. If the device is integrated into a network, its polling address must
be greater than zero. In this mode the signal of the analog loop does not represent a
quantity measured by the device. A host and/or a field communicator can be integrated
into the bus as communication master(s). The number of devices in the network is limited
by the number of possible device addresses.
