Specification

Part Number: IS420UCSBH1A

Manufacturer: General Electric

Country of manufacture: USA

Product Type: UCSB Controller Module

Series: Mark VIe

The IS420UCSBH1A is a UCSB controller module developed by General Electric.The UCSB controller is a stand-alone computer that performs application-specific control system logic.

UCSB controllers are stand-alone computers that execute application-specific control system logic. Unlike conventional controllers, UCSB controllers do not carry any application I/O. In addition, all I/O networks are connected.

In addition, all I/O networks are connected to each controller to provide all input data.

The hardware and software architecture ensures that no single point of application input is lost if the controller is powered down for maintenance or repair.

Operation

The controller comes preloaded with application-specific dcs-sis.com software. It can run ladders or blocks. Minor changes to the control software can be made online without rebooting the system.

The IEEE 1588 protocol is used to synchronise the clocks of the I/O components and the controller to within 100 microseconds via R, S, and T IONets.

External data is transferred to the controller’s control system database via R, S and T IONets.

Process inputs and outputs for the input/output modules are included.

The following are also included in a dual system:

Internal state values and initialisation information for the specified controller

State and synchronisation information for both controllers

Also includes the following in a triple-module redundant (TMR) system:

Internal state values for voting and status, and synchronisation information from all three controllers

Initialisation data from the specified controller
