More Information

Overview Manuals Controller Design Network Interfaces Backup & Restore Installation

Features:

  • Runs Mark VIe application code on a 600 MHz Intel EP80579 processor.
  • Uses ECC memory and QNX Neutrino for deterministic industrial control.
  • Receives distributed I/O data through three dedicated IONet Ethernet interfaces.
Operates without a battery, cooling fan, or hardware jumper setup.

The General Electric IS420UCSBH1A keeps application execution separate from the distributed I/O packs, allowing every redundant controller to receive the input data it needs.

Network identity and the restored ControlST application are the central service items for General Electric IS420UCSBH1A; there are no field jumpers to copy.

All prices are shown in USD.

Processing and retained resources

  • CPU: 600 MHz Intel EP80579 executes the downloaded control blocks and ladder logic.
  • Working memory: 256 MB DDR2 SDRAM includes error-correcting code.
  • Program storage: 2 GB NAND flash holds controller software and application data.
  • Operating system: QNX Neutrino provides real-time multitasking behavior.
  • Non-volatile data: Supported program variables, forces, and totalizers depend on ControlST release.

Five Ethernet connections with separate duties

  • ENET1: ENET1 supports ToolboxST, HMI alarms, and EGD application communication.
  • ENET2: ENET2 can be assigned to supported Ethernet Modbus, OPC UA, or CDH service.
  • IONet: Three IONet ports communicate only with Mark controls I/O modules and controllers.
  • Cable coding: Red, black, and blue cabling preserves the intended redundant I/O topology.
  • Redundancy design: Controller and I/O-network redundancy must be configured as one coordinated design.

Replacement data path

  • Controller backup: Create a verified controller backup before disturbing a running unit.
  • Identity record: Record the controller IP address, ControlST version, firmware, and hardware identity.
  • Address transfer: Transfer the address by the approved flash-drive or COM1 procedure.
  • Application restore: Restore the application only after confirming model and software compatibility.
  • State comparison: Compare non-volatile variables, forces, totalizers, and controller state before release.

Panel and startup checks

  • Mounting: Mount the controller directly to sheet metal in the required orientation.
  • Airflow: Keep the vertical airflow path through the heat-sink fins unobstructed.
  • DC supply: Verify the 28 VDC supply polarity and peak-power allowance before energizing.
  • Network reconnection: Reconnect plant Ethernet and each colored IONet lead to its recorded port.
  • Startup check: Confirm boot LEDs, time synchronization, network health, and application state.
Description
A 600 MHz standalone execution platform for Mark VIe applications is provided by the General Electric IS420UCSBH1A UCSB Controller Module. It runs the configured application rather than hosting field I/O on a backplane, and every controller receives the plant input data through dedicated IONet Ethernet paths.

A 600 MHz Intel EP80579 processor, 256 MB of ECC-protected DDR2 memory, and 2 GB of NAND flash form the computing platform inside General Electric IS420UCSBH1A. QNX Neutrino provides the real-time multitasking operating environment used by ControlST application logic.

Two plant-network interfaces and three IONet ports give General Electric IS420UCSBH1A separate paths for ToolboxST, alarms, EGD data, supported Ethernet services, and I/O-module communication. The fanless unit has a built-in supply, requires no battery or hardware jumpers, and mounts with unobstructed vertical airflow.

When replacing General Electric IS420UCSBH1A, transfer the approved controller IP address and application, then confirm ControlST version compatibility, network color assignments, time synchronization, and the backup/restore status before the control is returned to automatic operation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must be backed up before replacing IS420UCSBH1A?
Save the IS420UCSBH1A application, IP address, controller configuration, firmware level, network assignments, and any supported non-volatile variables.
Why can IS420UCSBH1A run while an HMI cannot communicate with it?
Check IS420UCSBH1A ENET1/ENET2 addressing, switch links, alarm path, EGD configuration, and ToolboxST network settings separately from application execution.
How should the three IONet cables on IS420UCSBH1A be reconnected?
Match the IS420UCSBH1A red, black, and blue IONet ports to the saved network map; do not interchange cables by physical reach.
Does IS420UCSBH1A require a replacement battery?
No. IS420UCSBH1A is designed without a battery and uses flash-backed resources for the supported controller data.
What airflow is required around IS420UCSBH1A?
Mount IS420UCSBH1A in the required orientation and keep vertical airflow through its heat-sink fins unobstructed.
How is an IP address transferred to IS420UCSBH1A?
Use the approved flash-drive or COM1 transfer procedure for IS420UCSBH1A, then verify the address before connecting it to the live control network.
What should be checked when IS420UCSBH1A stops at the boot LED?
Review the IS420UCSBH1A boot indication, supply voltage, flash media, firmware compatibility, restored configuration, and network connections before reloading software.
