A unit in batch control denotes a set of equipment and control devices for a specific process. A unit can be operated and monitored using a single unit block. For example, by assigning a unit block to a process unit, such as a reactor unit or a crystallization unit, operation and monitoring of the unit can be performed using a single block, which representing the entire process unit. Thus, operating a unit block actually means operating the entire process unit. Using a unit block dramatically simplifies the operation and monitoring of many instruments that have many tag names.

Unit Instrument Application(An Example of Reactor Unit)

In order to operate and monitor the subsystems of the auxiliary devices controlled by Programmable Controller(PLC),various types of analyzers and other instruments for the integrated plant automation, FCS subsystem communication capability enables connection with the subsystems, and also supports dual-redundant configuration.

The subsystems include Mitsubishi MELSEC, Allen Bradley PLC-5 and SLC500, Modbus compatible devices, Siemens SIMATIC, Omron SYSMAC, Yokogawa FA-M3, Darwin, and DAQSTATION and so on.

CS Batch 3000 is an ISA S88-based total batch process operation and management package that embodies Yokogawa's decades of experience in batch control. CS Batch 3000 provides simple operation and productive engineering for complex batch control. The package can also be easily linked to supervisory scheduling systems and information systems.
