FUNCTIONAL DESCRIPTION:

IS420ESWBH1A REV- C is a 16-Port Ethernet IONet Switch 10/100Base-TX manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. ESWBs are specifically designed to meet the needs of real-time industrial control solutions and are required for all IONet switches used in a Mark* VIe and Mark VIeS Safety control system. Each hardware form is available in five versions (H1A through H5A)that vary in fiber-optic port configuration options, which include no fiber ports, multi-mode fiber ports, or single-mode (longer distance) fiber ports. Refer to the IS420ESWAH#A IONet Switch Specifications table and the IS420ESWBH#A IONet Switch Specifications table for these fiber option details. The device supports robust Ethernet communication and networking capabilities, offering the following key features:

• IEEE Standards Compliance: Fully compatible with IEEE 802.3 (10 Mbps Ethernet), IEEE 802.3u (100 Mbps Fast Ethernet), and IEEE 802.3x (Full-Duplex and Flow Control), ensuring interoperability with a wide range of network devices and protocols.

• 10/100Base-TX Ethernet Ports: Equipped with auto-negotiation functionality, the device supports both 10 Mbps and 100 Mbps copper Ethernet connections, automatically selecting the best speed based on the connected device.

• Full/Half Duplex Operation: Auto-negotiation enables the ports to operate in either full-duplex or half-duplex mode, optimizing network performance based on the capabilities of connected devices.

• 100 Mbps Fiber Uplink Port: Includes a dedicated 100 Mbps FX uplink port, allowing high-speed fiber optic connectivity for extended distance networking and improved data transmission reliability in industrial environments.

• HP Auto-MDIX Support: Features HP-MDIX (Automatic Medium-Dependent Interface Crossover) on all copper ports, enabling automatic detection and configuration of crossover or straight-through Ethernet cables, simplifying installation and reducing cabling issues.

DISTRIBUTED I/O MODULES:

The I/O modules contain three basic parts: terminal board, terminal block, and I/O pack. The terminal board mounts to the cabinet and comes in two basic types: S and T. The I/O pack mounts to the terminal board J-port connector. Both terminal board types provide the following features:

• Terminal blocks for I/O wiring
• Mounting hardware
• Input isolation and protection
• I/O pack connectors
• Unique electronic ID

I/O PACKS:

I/O packs have a common processor board and a data acquisition board that is unique to the type of connected device. I/O packs on each terminal board digitize the I/O variables, perform algorithms, and communicate with the controller. The I/O pack provides fault detection through a combination of special circuitry in the data acquisition board and software running in the Central Processing Unit (CPU)board. The fault status is transmitted to and used by the controllers. The I/O pack transmits inputs and receives outputs on both network interfaces if connected. Each I/O pack also sends an identification message (ID packet) to the main controller when requested. The packet contains the hardware catalog number of the I/O board, the hardware revision, the board barcode serial number, the firmware catalog number, and the firmware version. The I/O packs have a temperature sensor that is accurate to within ±2°C (±3.6 °F). Every I/O pack temperature is available in the database and can be used to generate an alarm.

TERMINAL BOARDS:

Signal flow begins with a sensor connected to a terminal block on a board. Wide and narrow terminal boards are arranged in vertical columns of high and low-level wiring. An example of a wide board is a board that contains magnetic relays with fused circuits for solenoid drivers. A shield strip is provided to the left of each terminal block. It can be connected to a metal base for immediate grounding or floated to allow individual ground wires from each board to be wired to a centralized, cabinet ground strip.

The ESWx switches can be DIN-rail mounted using one of three GE-qualified DIN-rail mounting clips, depending on the hardware form (ESWA or ESWB) and the selected DIN-rail mounting orientation. The clips are ordered separately, according to the following table. Mounting screws are included with each switch.

FREQUENTLY ASKED QUESTIONS:

What type of Ethernet ports are provided on the switch?

The switch is equipped with 16 copper Ethernet ports that support 10/100Base-TX, allowing both 10 Mbps and 100 Mbps data transmission speeds. These ports use RJ45 connectors and support auto-negotiation for speed and duplex modes, making the switch suitable for connecting a range of industrial Ethernet devices.

Does the switch support auto-negotiation and auto-MDIX?

Yes, the switch features both auto-negotiation and HP Auto-MDIX functionality. Auto-negotiation allows the switch to automatically adjust the speed and duplex mode of each port based on the connected device. Auto-MDIX eliminates the need for crossover cables by automatically configuring the port to match the type of Ethernet cable being used.

What is the speed and duplex capability of the switch's Ethernet ports?

Each of the 16 copper Ethernet ports on the switch supports both 10 Mbps and 100 Mbps speeds. These ports are equipped with auto-negotiation capabilities, allowing them to automatically select the best operational speed and duplex setting—either half-duplex or full-duplex—depending on the connected device. This adaptive behavior improves overall network performance and communication stability.
