Machine Control Functions
Reduce wiring, save space, and minimize PC load by controlling equipment with
a few low-capacity PCs dispersed near each piece of equipment rather than a
single centralized PC.
Use remote I/O to save resources and space.
Receive high-speed count
inputs
(For example, calculating
length or position with an
encoder).
Generate a pulse output based on a multiple of an input pulse to synchronize
control of a peripheral process with the main process.
The multiple for the peripheral process (such as tool feed rate) can be changed
during operation by calculating the multiple from another input value (such as an
encoder) in the peripheral process.
This method can be used to change the process for different products or models
without stopping the equipment.
Reliably receive input pulses with an ON-time shorter than the cycle time (such
as inputs from a photomicrosensor).
Interrupt functions
Perform simple positioning by outputting pulses to a motor driver that accepts
pulse-train inputs.
Receive an analog input and output an analog output.
Receive temperature sensor input directly at the PC.
Usage
Max. count frequency of 2 kHz (single-phase)
Max. count frequency of 5 kHz (differential
phase) or 20 kHz (single-phase)
Execute a special process very quickly when an
input goes ON.
(For example, operating a cutter when an inter-
rupt input is received from a Proximity Switch or
Photoelectric Switch.)
Count input ON pulses and execute a special
process very quickly when the count reaches the
preset value.
(For example, stopping the supply feed when a
preset number of workpieces have passed
through the system.)
Execute a special process at a preset count
value.
(For example, cutting material very precisely at a
given length.)
Execute a special process when the count is
within a preset range.
(For example, sorting material very quickly when
it is within a given length range.)
Execute a special process when a timer times
out.
(For example, stopping a conveyor at very pre-
cise time (independent of the cycle time) after the
workpiece is detected.)
Repeat a special process at regular intervals.
(For example, the speed of a sheet feeder can be
monitored by measuring the input signal from an
encoder at regular intervals and calculating the
speed.)
Function
Distributed control using DeviceNet
Use CompoBus/S Remote Terminals.
Use interrupt input (counter mode) to read
the present value without interrupts.
Use high-speed counter to read the present
value without interrupts.
Pulse synchronization
Quick-response input function
Interrupt input (interrupt input mode)
Interrupt input (counter mode)
High-speed counter interrupt generated
when the count matches the set value.
High-speed counter interrupt generated
when the count is within the set range.
Interval timer interrupt
(One-shot mode)
Interval timer interrupt
(Scheduled interrupt mode)
Pulse output function
Analog I/O Unit
(Connect the Analog I/O Unit to the CPU
Unit.)
Temperature Sensor Unit
(Connect the Temperature Sensor Unit to
the CPU Unit.)
