Sysmac CQM1-CPU21,PA206, OC222 PLC Omron Module Assembly

The CQM1 is a compact, high-speed PC made up of a CPU Unit, Power Supply Unit, and I/O Units that together provide up

to 256 total I/O points. These components lock together at the sides, allowing simple changes in the size and capacity of the

PC. There are six types of CPU Unit, shown in the table below. All of the CPU Units except for the CQM1-CPU11-E have a

built-in RS-232C interface.

The CQM1 provides many advanced features, including the following:
· The CPU Unit provides 16 built-in input terminals.
· I/O Units can be added to increase I/O capacity.
· The CQM1 is much faster: about 20 times faster than P-type PCs.
· High-speed timers and counters are built in.
· Outputs are processed when instructions are executed (direct outputs).
The CQM1 supports three types of interrupts:
· Input Interrupts
Input interrupts are used to process input signals from an external device that are shorter than the program execution time. Input

signals with a pulse width as short as 0.1 ms can be used.
· Scheduled Interrupts
Scheduled interrupts can be performed using a high-speed interval timer.
· High-speed Counter Interrupts
· Single-phase pulses up to 5 kHz and two-phase pulses up to 2.5 kHz can be input. High-speed counter interrupts can be combined

with pulse outputs for applications such as motor control. The CQM1-CPU43-EV1 and CQM1-CPU44-EV1 can accept single-phase

pulses up to 50 kHz and two phase pulses up to 25 kHz. The high-speed counter (absolute encoder input for the CPU44-EV1) has two

points added. Pulse Output Function Pulses up to 1 kHz can be output from Output Unit contacts. The CQM1-CPU43-EV1 has two

dedicated ports for outputting 50 kHz pulses.
