Using a Quantum 984 HSBY System

Configuring 984 HSBY

CHS software To configure a 984 HSBY system, you must load the CHS software into the controllers. The software is included on a diskette in the Hot Standby kit. Once you have loaded the software, you can choose how to proceed. You may control your Hot Standby system through ladder logic or you can use a configuration extension.

The CHS	The logic in the CHS loadable is the engine that drives the Hot Standby capability in
Loadable	a Quantum control system. The CHS loadable gives you the ability to:

specify the Hot Standby command register, which is used to configure and control Hot Standby system parameters

define a Hot Standby status register, which can be used to monitor the real

lmachine status of the system

implement a CHS instruction in ladder logic

Unlike HSBY (a comparable loadable used for Hot Standby configurations in 984 controllers), the CHS instruction does not have to be placed in a ladder logic program. However, the CHS software must be loaded into the Quantum controller in order for a Hot Standby system to be supported.

Installing the The following steps are only necessary if the CHS loadable is not already part of

CHS loadable your 984 installation. The CHS loadable is provided on a 3 1/2 diskette

into the 984 (140 SHS 945 00) as part of your 140 CHS 210 00 Hot Standby kit. The file is named

Environment QCHSVxxx.DAT, where xxx is the three-digit version number of the software.
