The IS420UCSCH1B from GE Vernova belongs to the Mark VIe Functional Safety System. This UCSC gateway controller operates as a stand-alone unit. Unlike traditional controllers, it does not use a backplane for I/O. Instead, it relies on IONet interfaces for communication.
Many power generation sites use the IS420UCSCH1B for gas and steam turbine control. Additionally, this controller supports real-time hypervisor technology. You will find it ideal for high-reliability industrial applications.
This controller houses a 1.2 GHz AMD G-Series quad-core processor. It includes 4 GB of DDR3-1333 SDRAM with ECC memory. For nonvolatile storage, the board uses NVSRAM. Specifically, it holds 3067 program variables, 64 totalizers, and 338 forces.
The IS420UCSCH1B provides six Ethernet ports in total. Five ports sit on the front panel. One additional bottom port handles Predix connectivity. Furthermore, the board supports three redundancy configurations: simplex, dual, and TMR.
Embedded Field Agent (EFA) technology enables cloud-based applications. Meanwhile, embedded EtherCAT and PPNG improve real-time data delivery. The QNX Neutrino OS (version 6.5 or 7.1) ensures multitasking capability.
Dimensions (with mounting): H 8.03 in x D 5.99 in x W 2.17 in
Weight: 1.33 kg
Operating temperature: -40°C to 70°C
Storage temperature: -40°C to 85°C
Altitude for normal operation: 0–1000 m (101.3 to 89.9 kPa)
Cooling type: Convection
Power supply voltage: 18–32 VDC (nominal 28 VDC)
The IS420UCSCH1B includes a non-replaceable 4 A, 125 V DC fuse. Its surge protection meets nominal melting rating of 26 A² sec. Additionally, the board uses conformal coating for PCB protection.
First, mount the IS420UCSCH1B vertically on a DIN rail. Ensure proper convection cooling around the unit. Next, connect the IONet ports (R/S/T) to I/O modules. Use these ports for simplex, dual, or TMR configurations.
For dual redundancy, use the S/SL2 and R/SL1 ports only. For TMR applications, all three IONet ports are required. Then, configure the UDH network IP address using ToolboxST V07.00.00C or later.
A physically managed switch divides the networks. This keeps Mark VIe control data isolated from cloud traffic. Finally, set the default IP address (192.168.101.111) to match your site HMI requirements.
The hypervisor creates a virtual network between VMs. Specifically, the EFA and Mark VIe control run as separate VMs. Data transfers between them through this virtual network.
For diagnostics, the IS420UCSCH1B performs system limit checking. Each analog input has both software and hardware limits. Two occurrences typically trigger a hardware limit alarm. ToolboxST provides access to all diagnostic messages.

1. Can the IS420UCSCH1B work without a backplane?
Yes. Unlike conventional controllers, this IS420UCSCH1B does not host I/O on a backplane. It uses IONet ports instead.
2. What HMI software is compatible?
ControlST V07.00.00C or later is required for configuration and monitoring.
3. How many Ethernet ports does this controller provide?
The IS420UCSCH1B gives you six Ethernet ports total. Five are on the front panel, and one is on the bottom for Predix.
4. Which redundancy modes does it support?
It supports simplex, dual, and TMR redundancy configurations through its IONet ports.
5. What is the default IP address of the module?
The default IP address is 192.168.101.111. You can change it using ToolboxST.
