The Omron CQM1 Programmable Logic Controller (PLC) series provides a reliable solution for diverse industry processes with advanced capabilities tailored to suit various manufacturing environments. Known for their dependability, efficiency, and versatility, the CQM1 PLCs are well-suited for creating sophisticated control systems in industries such as manufacturing, packaging, and material handling.

Current Consumption

Current consumption is a critical factor in the power efficiency of the Omron CQM1 PLCs. For instance:

• CQM1-CPU43-EV1-CE: Operates at 980 mA at 5V DC.

• CQM1-AD041 Analog Input Unit: Consumes just 80 mA at 5V DC.

• CQM1-B7A01 Expansion I/O Module: Supports up to 512 I/O points with input and output currents of 7 mA and 0.5A per point respectively. These values demonstrate optimized power utilization across various industrial sectors.

Programming Logic Language

The CQM1 series supports multiple programming languages, such as:

• Ladder Logic

• Structured Text (ST)

• Sequential Function Chart (SFC)

• Instruction List (IL)

• Function Block Diagram (FBD)

For instance:

• CQM1-CPU45-EV1: Supports all five languages.

• CQM1H-CPU11: Specializes in Ladder Logic and includes 3K word memory for complex programs. This flexibility allows engineers to tailor programming to their application needs.

Interrupts

Interrupts enhance real-time responsiveness in automation:

• CQM1-B7A13: Offers three scheduled interrupt capabilities for immediate response to external events.

• CQM1-SRM21-V1: Supports both scheduled and external interrupts. These features are essential for applications requiring precision timing, such as motion control.

Communication

The CQM1 PLCs support a variety of protocols and interfaces:

• CQM1-CPU43-EV1-CE: Features RS-232C and RS-422A/485 ports with support for SYSMAC Link and Host Link protocols.

• CQM1-B7A01: Includes an RS-232C port for device integration.

• CQM1-LK501: Enables data rates up to 187.5 kbps for long-distance communications. These features ensure seamless data flow between PLCs and peripheral devices.

Input/Output Instructions

CQM1 PLCs offer intuitive I/O commands:

• TEN KEY INPUT: Reads 8-digit BCD data from keypads.

• HEXADECIMAL KEY INPUT: Processes hexadecimal input.

• DIGITAL SWITCH: Reads 4 or 8-digit BCD data.

• 7-SEGMENT DISPLAY EXPORT: Outputs numeric values to visual displays. Modules like CQM1-ID211 and CQM1-OC222 handle digital input/output effectively, simplifying complex control logic.

Data Memory Capacity

Memory capacity determines the PLC's ability to store and execute programs:

• CQM1-CPU45-EV1: Offers 32K words of data memory.

• CQM1-ME08K: A memory cassette with 8K words.

• CQM1-ME04K: A ROM module with 4K word capacity. This capacity enables complex strategies for automation systems.

Supply Voltage

Various modules operate on different supply voltages:

• CQM1-B7A01: 12–24V DC

• CQM1-PR001-E: 5V DC

• CQM1-ID211: 24V DC These voltage ranges enhance compatibility across control systems.

Transmission Speed

Data transmission speed is vital for real-time operations:

• CQM1-SRM21-V1: Offers high-speed modes (reaction times: 3–19.2 ms).

• CQM1-B7A13: Uses time-division multiplexing.

• CQM1-LK501: RS-485 at 187.5 kbps with up to 200m range. These capabilities ensure timely communication across distributed control systems.

Weight and Dimensions
