Interrupt functions
Perform simple positioning by outputting pulses to a motor driver that
accepts pulse-train inputs.
Basic Functions
Usage
Set the cycle time to a fixed interval.
Stop PC operation when the cycle time exceeds a
maximum setting.
Keep all outputs ON when PC operation stops.
Retain the contents of I/O memory when starting
operation.
Retain the contents of I/O memory when the PC is
turned ON.
Eliminate effects from chattering and external noise.
Maintenance Functions
Usage
Record data with time-stamp.
Establish user-defined errors for desired input
conditions. (Fatal and non-fatal errors can be defined.)
Read the number of power interruptions.
Set the startup operating mode.
Usage
Execute a special process very quickly
when an input goes ON.
(For example, operating a cutter when an
interrupt 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
precise 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.)
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
Function
Set a minimum (fixed) cycle time in the PC Setup.
Set a maximum (watch) cycle time in the PC Setup.
Turn ON the IOM Hold Bit (SR 25212).
Turn ON the IOM Hold Bit (SR 25212).
Turn ON the IOM Hold Bit (SR 25212) and set the PC
Setup (DM 6601) so that the status of the IOM Hold Bit
is maintained at startup.
Set a longer input time constant in the PC Setup.
Function
Clock/calendar function
FAL(06) defines non-fatal errors. (PC operation
continues.)
FALS(07) defines fatal errors. (PC operation stops.)
The number of power interruptions is stored in AR 23.
Set the startup operating mode in the PC Setup
(DM 6600).
