Functions
J CONFIGURATION
The CPM1A CPU units feature a compact, one-piece
construction that includes 10, 20, 30 or 40 built-in I/O terminals.
Three output models are available: Relay outputs, sinking (NPN)
transistor output and sourcing (PNP) transistor output.
Expansion
Up to three Expansion I/O Modules can be connected to a
30-point or 40-point CPU Unit to add an extra 8 or 20 I/O points
for each, for a maximum of up to 100 I/O points.
Dedicated I/O Modules
Up to 3 Analog I/O Modules or Temperature Sensor Input
Modules can be used with 30-point and 40-point CPU Units.
Each analog I/O module provides 2 analog inputs and 1 analog
output, so a maximum of 6 analog inputs and 3 analog outputs
can be achieved by connecting 3 Analog I/O Modules. Each
Temperature Sensor Module provides two temperature sensor
inputs from either thermocouples or platinum resistance
thermometers. Up to 6 inputs can be connected.
J INTERRUPT INPUTS
There are two input interrupts in the CPM1A 10-point I/O CPU
and four in the 20-, 30-, and 40-point I/O CPUs. Input interrupts
are available in two modes.. In addition to normal interrupt inputs,
the CPM1A has a counter mode that counts high-speed input
signals and triggers interrupts at fixed count multiples.
Input Interrupt Mode
CPM1A
If an input interrupt occurs, the regu-
lar program shuts down irrelevant of
the cycle time, and the interrupt pro-
cessing program is executed im-
mediately.

Application Example:
Cutting Metal Sheets to Specified Lengths
The proximity sensor detects the edge of a
metal plate to operate the cutter. Metal sheets
can be cut continuously to the specified
lengths at a high speed.
