Omron CQM1 Modular PLC Control Series Units

March 6, 2013 - PRLog -- The Omron CQM1 range of modular PLC Controllers are a compact, high speed PC composed of a Power Supply Unit, a CPU unit and I/O units. All of these units connect at the sides to form a single PC, which is normally mounted to a DIN track.
All CQM1 CPU units, except for the CQM1-CPU11-E are equipped with an ES-232C port which can be connected directly to a host computer, another CQM1 or other serial devices.

While this range of Omron products has become obsolete, More Control have stock of most of the CQM1 range of products and can program systems & automation applications using CQM1 products.

If you are looking for spare CQM1 units or are looking to upgrade your existing range of CQM1 units to modern Omron PLC systems (http://www.more-control.com/plc-programming.html), More Control can assist you each step of the way.

Omron CQM1 Main Features:

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 increased I/O capacity
The CQM1 is much faster: about 20 times faster than P-type PC’s
High Speed timers and counters are built in
Outputs are processed when instructions are executed (direct outputs)

The CQM1 Support 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 5Khz 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 the Output Unit contacts. The CQM1-CPU43-EV1 has two dedicated ports for outputting 50 kHz pulses.

Communications:
A peripheral port and RS-232C port are available and are used to communicate with external devices using the following methods:

Host Link:
The CQM1 using the host link can communicate with a personal computer and programmable terminal using host link commands.

RS-232C
The CQM1 using the RS-232C can read data from a bar code reader or measurement device and output data to a printer

1 to 1 Link:
A data link can be created with a data area in another CQM1 to monitor the other PC’s status and synchronize processes controlled by the PC’s.

Analogue Setting Function:
The CQM1-CPU42-EV1 provides volume controls with four channels for adjusting analogue settings.

Convenient I/O instructions:
A single instruction can be used to input or output data, simplifying the program.
The TEN KEK INPUT instruction can be used to read 8-digit BCD input from a ten-key

The HEXADECMIAL KEY INPUT instruction can be used to read 8-digit hexadecimal key input data from I/O Units

The DIGITAL SWITCH instruction can be used to read 4 or 8 digit BCD data from digital switches

The 7-SEGMENT DISPLAY OUTPUT instruction can be used to output 4 or 8-digit data to 7-segment displays

Macros:
The MACRO instruction can be used to call and execute subroutines, designating the I/O word for the subroutine as an argument. Using an argument to specify a subroutine I/O words allows subroutines to be used more easily in different locations, simplifying the program.

Differentiation Monitoring
Up to now, differentiation monitoring was available only in top of the line PC’s. Differentiation monitoring indicates when a bit goes from OFF to ON or from ON to OFF. It can be used to monitor the status of inputs or bits that turn on and off in very short intervals.

Omron CQM1 CPU Units
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 units (all of the CPU units except for the CQM1-CPU11-E have a built in RS-232C interface.

Model  Maximum I/O points  Program Capacity (words)  DM capacity (words)  RS-232C port  Analogue Setting  Pulse I/O  ABS interface  AD/DA conversion
