Schneider Electric 140CHS 1100 Communication Module

Schneider Electric 140CHS 1100 Communication Module

140CHS 1100 is the core communication module of Schneider Electric's Modicon Quantum series PLC, mainly used to connect Quantum controllers with industrial Ethernet networks. It supports mainstream industrial communication protocols such as Modbus TCP/IP, has high stability, flexible expansion, and redundant communication capabilities, and is suitable for the needs of equipment networking, data exchange, and remote monitoring in industrial automation, process control, and other scenarios. It is a key component in building Ethernet communication architecture for Quantum systems.

Basic Information and Product Positioning

1. Core identification and ownership

Product model: 140CHS 1100 (unique ordering and hardware identification code)

Product series: Modicon Quantum (Schneider's high-end PLC product line, aimed at large-scale industrial control scenarios)

Function positioning: Ethernet communication interface module, as the "network gateway" of Quantum controller, realizing the connection between the controller and the upper computer (such as SCADA system HMI）、 Ethernet data exchange for other PLCs or industrial equipment.

Substitution and Compatibility: There is no direct substitute model, compatible with the full range of Modicon Quantum controllers (such as 140CPU65150, 140CPU67160), and supports collaboration with other modules in the Quantum series (such as I/O modules, specialized functional modules).

2. Core values

Protocol standardization: Native support for Modbus TCP/IP protocol, compatible with industrial Ethernet universal standards, no additional protocol conversion required, reducing system integration complexity.

Communication stability: Adopting industrial grade hardware design, it can withstand electromagnetic interference and environmental fluctuations in industrial sites, ensuring long-term continuous communication without interruption.

Redundancy Support: Supports dual module redundancy configuration (in conjunction with Quantum system redundancy function), automatically switches in case of failure, improves communication link reliability, and is suitable for critical control scenarios such as petrochemicals and power dispatch.

Hardware specifications and electrical characteristics

1. Physical and interface specifications

Size and Installation:

Dimensions: Complies with the Quantum series standard module dimensions (height 130mm x width 36mm x depth 110mm, specific subject to physical object), adopts rail installation, compatible with Quantum standard rack (such as 140XTS00200 rack), occupies one module slot.

Weight: Approximately 0.3kg (excluding accessories), lightweight design does not increase rack load.

Communication interface:

Ethernet port: 1 RJ45 interface, supports 10/100Mbps adaptive speed, compatible with full duplex/half duplex modes, supports Auto MDI/MDI-X automatic line sequence adjustment (no need to distinguish between crossover and straight through lines), convenient for on-site wiring.

Status indicator lights: 2 LED indicator lights (Link/Activity light: green, constantly on indicates link connectivity, flashing indicates data transmission; Fault light: red, constantly on indicates module failure, off indicates normal), visually judging the communication and module status.

2. Electrical parameters

Power supply demand:

Power input: Powered from the Quantum rack backplane, supports DC 5V (typical current 1.2A, maximum current 1.5A), does not require external independent power supply, simplifies wiring.

Power consumption: Typical power consumption is 6W, maximum power consumption is 7.5W, low-power design reduces the overall power load of the rack.

Electromagnetic compatibility (EMC):

Compliant with EN 61000-6-2 (industrial environment immunity) and EN 61000-6-4 (industrial environment emission) standards, it can withstand electrostatic discharge (ESD) ± 8kV (contact discharge) and ± 15kV (air discharge), and has a radio frequency radiation immunity of 10V/m (80-1000MHz), suitable for strong industrial interference environments.

Environmental adaptability:

Working temperature: 0 ° C~60 ° C (non condensing), storage temperature: -40 ° C~85 ° C, suitable for high and low temperature fluctuations in industrial sites.

Humidity: 5%~95% relative humidity (no condensation), resistant to humid environments, no additional moisture-proof measures required.

Communication functions and protocol characteristics

1. Core communication protocol

Modbus TCP/IP：

Role support: Can serve as a Modbus TCP server or client. In server mode, it supports up to 32 concurrent client connections (such as 32 HMIs accessing simultaneously). In client mode, it can actively access other Modbus TCP servers (such as reading remote PLC data).

Data Interaction: Supports Modbus standard function codes (such as 03H read hold register, 06H write single register, 10H write multiple registers), with a maximum data length of 125 registers (16 bits per register), meeting the requirements of batch data transmission in industrial control.

Communication efficiency: At a speed of 100Mbps, the response time of a single Modbus command is ≤ 10ms (within the local area network), ensuring real-time control requirements (such as millisecond level data acquisition and command issuance).
