Configurable Flowmeter Module Features and Operational Modes
22
Fully Software Configurable
The programming software uses a custom, easily understood interface to write
configuration. All module features are enabled or disabled through the I/O
configuration portion of the software.
You can also use the software to interrogate any module in the system to
retrieve:
•
serial number
•
revision information
•
catalog number
•
vendor identification
•
error/fault information
•
diagnostic counters.
By eliminating such tasks as setting hardware switches and jumpers, the
software makes module configuration easier and more reliable.
Electronic Keying
The electronic keying feature automatically compares the expected module, as
shown in the programming software I/O Configuration tree, to the physical
module before I/O communication begins. You can use electronic keying to
help prevent communication to a module that does not match the type and
revision expected.
For each module in the I/O Configuration tree, the user-selected keying option
determines if, and how, an electronic keying check is performed. Typically,
three keying options are available:
•
Exact Match
•
Compatible Keying
•
Disable Keying
You must carefully consider the benefits and implications of each keying
option when selecting between them. For some specific module types, fewer
options are available.
