Configurable Flowmeter Module Features and Operational Modes 33
Producer/Consumer Model
By using the Producer/Consumer model, ControlLogix CFM modules can
produce data without having been polled by a controller first. The modules
produce the data and any other owner controller device can decide to consume
it.
EXAMPLE
In this scenario, Disable Keying allows I/O
communication:
The module configuration is for a 1756-IA16 digital input
module. The physical module is a 1756-IB16 digital input
module. In this case, communication is allowed because the
two digital modules share common data formats.
IMPORTANT
Changing electronic keying selections online may cause the
I/O communication connection to the module to be
disrupted and may result in a loss of data.
