Function

Program storage and execution

Equipped with CMOS read/write memory, it stores user program instructions, I/O device status and numerical data.

It supports ladder diagram and function block programming. Users can input programs through industrial terminals (such as 1770-T3 or 1784-T50). The ladder diagram symbols are similar to those of traditional relay control systems, which is convenient for operation.

I/O control

It supports up to 896 I/O points and is compatible with various I/O modules (such as digital input/output, analog modules), capable of controlling a wide range of devices, including solid-state devices, thumb wheel switches, solenoid valves, alarm indicators, motors or motor starters.

It provides I/O enforcement functions to facilitate debugging and troubleshooting.

Advanced computing functions:

It supports arithmetic operations (addition, subtraction, multiplication, division), timer, counter and data transmission functions, and is suitable for complex control logic.

Support the expansion of arithmetic functions and relay-type functions to enhance program flexibility.

Network communication

Compatible with Allen-Bradley Data Highway, supports communication with other PLCS or industrial equipment, and is convenient for integration into large-scale control systems.

Fault Diagnosis:

Equipped with status indicator lights to detect processor or system faults and simplify troubleshooting.

The 4-position mode selection switch enables users to switch between operation, programming or test modes, facilitating system configuration and maintenance.

System configuration:

It is used in conjunction with scanners, interface modules, input/output modules and power supply modules (such as 1772-P1) to form a complete PLC-2/30 system.

Support users to choose modular configuration to adapt to different application requirements.

Program protection: Through the jumper Settings of the 1772-LH interface module, the function of prohibiting program modification can be enabled to prevent unauthorized modification of user programs or data tables (address 4008 and above).

Application scenarios

Manufacturing plant

It is used for production line control, such as in automotive manufacturing, food processing or electronic assembly, to control conveyor belts, robotic arms, sensors and actuators.

Complex sequential control and logical operations are achieved through ladder diagram programming.

Process control

In the chemical, oil and gas or pharmaceutical industries, process equipment (such as pumps, valves, heaters) is monitored and controlled to handle variables such as temperature and pressure.

Supports timer and counter functions, suitable for batch processing or continuous process control.

Material handling: In warehousing or logistics systems, control automated handling equipment, conveyor belts or sorting systems to ensure efficient material flow.

Energy management: In power distribution or renewable energy systems, manage switchgear, relays or monitoring devices to support highly reliable control tasks.

Traditional equipment upgrade: Applicable to the upgrade or maintenance of old systems from the 1980s (such as ABAR vacuum furnaces), maintaining the operation of legacy equipment while supporting Data Highway network integration.

Complex control tasks: Utilizing extended arithmetic capabilities and I/O enforcement functions, it is suitable for scenarios that require complex logic or data processing, such as measurement, monitoring, or pollution control.
