Chapter 3 Configurable Flowmeter Module Features and Operational Modes
Producer/Consumer Model
By using the Producer/Consumer model, the 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.
Module Status Information
The 1756-CFM module has status indicators on the front of the module that
allow you to check the module health and operational status.
These status can be checked with the status indicators:
•
Input point status
- display indicates a particular points status, including
specific indicators for the input F and Z points for each channel
•
Output point status
- display indicates the status of two output points on
the module
For an example of the status indicators, see
.
Configurable Flowmetering Channels
The module offers two configurable Flowmetering channels. Each channel
uses two Flowmeter inputs (F0 & F1) and two corresponding gate inputs (Z0 &
Z1).
Flowmeter Inputs
Two flowmeter inputs (F0 & F1) are available on your module. The inputs are
capable of receiving these input signals:
•
+/- 30V peak from passive Magnetic Pickups
•
5V DC logic (TTL compatible)
•
12-24V DC powered preamp outputs
