Controllers Model 354N Universal Loop Controller Introduction Features & Benefits Multiple loop capability provides control, logic, and sequencing functions to accommodate comprehensive process control needs Graphical configuration program allows use of function block and ladder logic languages in a control strategy configuration Scalable hardware minimizes initial costs, while providing for easy future expansion 2 Factory Configured Options (FCOs) minimize configuration time and expense Standard DB9/M connector provides easy connection to a PC for configuration, operation, monitoring, and troubleshooting RS485 Modbus network provides easy connection to a workstation via a multi-drop network for configuration, operation, monitoring, and troubleshooting Optional local faceplate provides full monitoring and controller configuration capabilities The ability to connect to the Local Instrument Link (LIL) in place of the MODBUS network provides higher speed and peer-to-peer communication Password protection provides individual security for various plant personnel LonWorks® digital fieldbus provides flexible I/O expansion and reduced wiring costs for continuous and discrete variables Coated circuit boards ensure reliable operation and environmental integrity Removable Real Time Clock/Configuration Board (RTC/ CB) option minimizes maintenance and complexity via a simple board replacement technique that stores a complete copy of the control strategy configuration Description The Model 354N Universal Loop Controller, a stand-alone, microprocessor-based industrial controller designed for use in a broad range of applications, is a wall-mounted version of the Model 353 Process Automation Controller. As such, it can function as a simple single-loop controller or as a multiloop controller providing complete control and logic for a small unit batch or continuous process. Moreover, the Model 354N’s fieldbus and networking options enable it to function as an integral element in a plantwide control system. 2.10 Each of the Model 354N’s configured loops can have a virtual operator faceplate for monitoring from the optional local faceplate, a local flat panel PC, or plant workstation. Station events, such as alarms and actions, are mapped to the controller network to enable the local PC or workstation to provide alarm and event management consistent with the local faceplate. Loop pushbuttons also provide dual operation from the faceplate or the operator PC. This product consistency allows the local faceplate to afford full backup monitoring and configuration capabilities in case of a network or PC failure. The Model 354N’s pre-configured library of FCOs enables selection of common basic controller types for quick field configuration and set-up. A large selection of reusable function blocks enable simple changes to FCOs or the design of a custom control strategy to meet a variety of process control applications. The Graphical 353 Configuration software accommodates configuration design, downloading, uploading, and on-line monitoring capabilities for improved management of control configurations. In addition, sequencer/ logic loops can be configured and monitored on-line in ladder logic format for those more familiar with this language.

The total number and type of I/O function blocks available in the Moore 354N depend on the installed hardware, and when available, can be used as needed within a configured loop. Loop function blocks can be used in the quantities indicated within each loop. Each configured loop can contain one operator display block & one controller block*. 2 Station Hardware I/O AIN1-4 - Analog Input AINU1-2 - Analog Input Universal AOUT1-3 - Analog Output DIN1-4 - Digital Input DINU1-2 - Digital Input, Universal DOUT1-2 - Digital Output ROUT1-2 - Relay Output LIL Peer To Peer Global Data I/O AIL01-99 - Analog Input_LIL AOL01-99 - Analog Output_LIL DIL01-99 - Discrete Input_LIL DOL01-99 - Discrete Output_LIL Lonworks Remote I/O AIP01-25 - Analog Input lev_Percent AOP01-25 - Analog Output lev_Percent DID1-6 - Digital Input lev_Discrete,16 Chan.
