Overview of the Very High Speed Counter Module
Effect of Values in On/Off Operation
Isolation of Outputs
The module provides 850V DC isolation between each of the outputs and
the FlexBus.
Connecting Outputs to Counters
You can connect any of the outputs to any of the counter inputs. In this way, it is
possible to use the outputs to reset a counter or to cascade counters. If using the
outputs this way, make certain that the output voltage is compatible with the
chosen input.
What the Module Does The very high speed counter module performs high-speed scaling calculation
operations for various industrial applications. The module interfaces with a
FLEX I/O family EtherNet/IP adapter which then communicates with a
programmable controller processor.
The adapter/power supply transfers data to and from the module over the
FlexBus. Instructions in the programmable controller facilitate this
communication and let you write output values and configure the module’s mode
of operation. Figure
FLEX I/O Communication Process on page 15 describes the
communication process.
Output turns on at
count value of 2000
Output remains energized for
3000 additional counts
Output turns off at
count value of 5000
Output turns off at
count value of 2000 Output turns on at
count value of 5000
When values in Counter On Value are less than
values in Counter Off Value. When values in Counter On Value are greater
than values in Counter Off Value.
