Core functions and features

(1) Input/output characteristics

Input mode: Supports static signals (+24V/0V) and dynamic signals (A/B/C pulse types). Dynamic signals can be connected in series with 10 safety sensors (such as emergency stop buttons and safety switches) through a single input, still meeting the PL e/SIL 3 level; Static signals require two inputs to achieve dual loop redundancy.

I/O flexibility: IQ terminals can be configured as safe inputs, non safe outputs, or as inputs/outputs simultaneously (such as reset buttons with indicator lights), reducing terminal occupancy.

Special Input: D20/D45 models support analog input (0-10V/4-20mA), D45 additionally supports 4-channel high-speed counters (up to 14kHz), which can achieve speed monitoring and position counting.

(2) Communication and Expansion Capability

Internal bus: Pluto bus (CAN protocol) supports interconnection of 32 PLC units, and I/O variables can be shared between units, with a fault response delay of 10-40ms.

External Gateway: Four types of gateways cover mainstream industrial buses, enabling bidirectional communication between Pluto systems and external systems

Gateway model supports bus core function order number

GATE-P2 Profibus DP transfers 64 Boolean values+8 16 bit registers 2TLA020071R8000

GATE-D2 DeviceNet supports CAN bridging and can expand bus length to 2TLA020071R8200

GATE-C2 CANopen supports PDO/SDO message transmission 2TLA020071R8100

GATE-E2 EtherNet/IP/PROFINET/Modbus TCP built-in web server, supporting 10/100M Ethernet 2TLA020071R8300

Security Encoder: Supports RSA 597 (single turn)/RSA 698 (multi turn) encoders, with up to 16 encoders connected to the bus, and achieves secure position/speed monitoring through dedicated function blocks.

(3) Programming and software support

Programming software: Pluto Manager (provided for free with the product and available for download from the official website), using ladder diagram programming and built-in 27 standard functional blocks certified by T Ü V (such as dual loop monitoring, dual hand control, mute function, etc.), simplifies safety logic design.

Programming process: Three steps to complete configuration – ① Define I/O type and signal mode; ② Named variables (input I/output Q/register R, etc.); ③ Drag and drop function blocks to build logic, and the program can be synchronized to all PLC units through the bus.

Identifier (IDFIX): Allocates bus addresses for multiple PLC projects, supports program storage and automatic loading, and is divided into four categories: R (read-only), RW (programmable), DATA (storing AS-i code), and PROG (storing single PLC programs).

​Application Cases and Security Assurance

(1) Typical application cases

Taking “robot cell+processing machine” as an example, through the interconnection of two Pluto PLCs (robot side+machine side), the following is achieved:

Emergency stop priority control: When an emergency stop is triggered, both the robot and the machine tool are stopped simultaneously;

Regional division: When the machine tool door is closed, the two operate independently, and when the door is opened, they are linked to stop the machine;

Alarm function: Display user error codes in the range of 200-299 through PLC to distinguish faults such as emergency stop, door opening, and unclosed cabin door.

(2) Safety compliance and assurance

Compliant with standards: EN 954-1 Cat.4, EN ISO 13849-1 PL e, IEC 61508 SIL 3, EN 61496-1 Type 4;

Fault detection: supports automatic detection of short circuits, sensor faults, bus faults, etc., and the safety output is immediately disconnected in case of a fault;

Data storage: Integrated UPS, keep variables stored in Flash during power outage, and restore defined state after restart.
