The K2 series PLC is an economical single product of the K series (partially non expandable), which improves performance and reduces costs on the basis of the K5 series, with extremely high cost-effectiveness.

■ Main characteristics

Provide a USB programming port, which can be powered by USB for debugging, greatly improving convenience;

DIO reuse patented technology, the same model can meet more application scenarios;

4 high-speed counting inputs and 3 high-speed pulse outputs;

Two RS485 channels, with a maximum baud rate of 115.2kbps;

• Support real-time clock;

Compact design, saving installation space.

Transistor type DIO (DI, DO multiplexing) point

Based on the DIO patented technology of Step Science, the K2 CPU module provides DIO points, which can be used as both DI and DO without configuration and can be wired for use.

USB programming port

Adopting MicroUSB programming interface, supporting USB2.0, compatible with common MicroUSB mobile data cables.

High-speed pulse counter

4 high-speed pulse counters. Each high-speed counter allows a maximum of 32 PV values to be configured and supports 32 segments of "CV=PV" interrupts;

Supports multiple modes, including single-phase, two-phase (Up/Down), AB phase (1x and 4x) counting, etc;

The maximum counting frequency of CP205 is 50KHz, while the maximum counting frequency of CP204 and CP209 is 200KHz

High speed pulse output

Three high-speed pulse outputs, with channels Q0.0, Q0.1, and Q0.4 respectively, all supporting PTO (pulse train) and PWM (pulse width modulation) output modes;

The maximum output frequency of CP205 is 50KHz; The maximum output frequency of CP204 and CP209 is 200KHz

The software provides PLS (PWM or PTO), positioning control command group, PFLO_S (follow command), etc.

Serial communication port

The CPU module provides two RS485 serial communication ports, named PORT1 and PORT2, with a maximum communication rate of 115.2k;

PORT1 port can be used as both a programming port and supports Modbus RTU slave protocol and free communication;

PORT2 port supports Modbus RTU master and slave protocols and free communication.
