Bristol® ControlWave® PAC
ControlWave I/O Expansion Rack
ControlWave I/O Expansion Racks allow for ex- pansion of I/O up to and including total plant wide control consisting of hundreds of I/O points. The process control application program resides in the main ControlWave process controller. It controls both local I/O as well as the I/O in the Expansion Racks. No control functionality is required in the I/O Expansion Rack.
Scalability
ControlWave I/O Expansion Racks allow for in- creased system flexibility depending on the process I/O count. The expansion racks provide a cost effective solution to large I/O count projects, and an economical approach to low or medium I/O count applications. ControlWave meets the needs of a wide range of applications.
The ControlWave I/O Expansion Rack consists of a 2, 4, or 8 slot ControlWave Chassis. The chassis contains an Ethernet communication engine dedi- cated to communications between the main proces- sor and the expansion I/O. The communication engine also supports timing functionality and battery backed RAM to retain outputs during short power outages. The ControlWave I/O Expansion Rack is connected to the main or host ControlWave control- ler rack via an Ethernet physical link using TCP/IP. Ethernet is widely accepted as a networking stan- dard physical data link that allows the ControlWave I/O Expansion Rack to fit into any local or wide area Ethernet based network, thereby increasing flexibility and providing an economical, reliable, I/O system.
