The CPM2C-S PCs are one-piece PCs with 10 I/O points (6 inputs and 4 out-
puts) in a built-in connector. There are 2 types of outputs available (sinking
transistor outputs, and sourcing transistor outputs). All CPM2C-S PCs require
a 24-VDC power supply.
CompoBus/S Slaves and up to 3 Expansion I/O Units can be connected to the
CPU Unit to increase the PC's I/O capacity to a maximum of 362 I/O points.
There are 23 different Expansion I/O Units available, including Units with 32
I/O points, 24 I/O points, 20 I/O points, 10 I/O points, 8 input points, 8 output
points, 16 inputs points, and 16 output points. The maximum I/O capacity of
106 I/O points is achieved by connecting three 32-point Expansion I/O Units
to the CPU Unit.
The CompoBus/S Master functions allow I/O Slaves to be connected provid-
ing an additional capacity of up to 256 I/O points (128 inputs and 128 out-
puts.)
Either a Programming Console or the CX-Programmer (version 2.1 or later)
can be used to program and monitor the CPM2C-S. Programs created on the
SYSMAC-CPT or SYSMAC Support Software can also be used.
Synchronized pulse control provides an easy way to synchronize the opera-
tion of a peripheral piece of equipment with the main equipment. The output
pulse frequency can be controlled as some multiple of the input pulse fre-
quency, allowing the speed of a peripheral piece of equipment (such as a sup-
ply conveyor) to be synchronized with the speed of the main piece of
equipment.

Pulses are output as a fixed multiple of the input frequency.
The CPM2C-S has a two kinds of high-speed counter inputs. The high-speed
counter input has a response frequency of 20 kHz/5 kHz and the interrupt
inputs (in counter mode) have a response frequency of 2 kHz.
• The single high-speed counter can be used in any one of the four input
modes: differential phase mode (5 kHz), pulse plus direction input mode
(20 kHz), up/down pulse mode (20 kHz), or increment mode (20 kHz).
Interrupts can be triggered when the count matches a set value or falls
within a specified range.
One high-speed counter can be used.
• The interrupt inputs (counter mode) can be used for incrementing
counters or decrementing counters (2 kHz) and trigger an interrupt (exe-
cuting the interrupt program) when the count matches the target value.
Two interrupt inputs can be used.
