HONEYWELL EXCEL 5000 OPEN SYSTEM

SPECIFICATION DATA

FEATURES
Various state-of-the-art communication options: Open LONW ORKS bus or C-bus communication; modem or ISDN terminal adapter at up to 38.4 Kbaud; wireless communication via GSM; dial-up through TCP/IP networks Unique features in open LONWORKS networks: NVBooster reduces the number of required NVs and thus also the number of required controllers; NV bindings can be restored after controller reset (and thus need not be redone after exchanging controllers); 46 NVs supported for LONW ORKS integration Reduced engineering and start-up costs: Huge variety of pre-tested and fully documented applications, configured with the PC-based Lizard application selector Easy and flexible installation: Screw terminals; mounting inside cabinet (DIN rail) or in cabinet front door Hardware / software options: With or without: XI582AH operator interface; Excel Online (formerly XI584) operator and service software; MMI (for buswide access to other controllers)

GENERAL

The Excel 50 controller has built-in communication capability, allowing it to be integrated into a Honeywell EXCEL 5000 System or into an open LonWorks network communicating rd with Excel 10 controllers as room/zone controllers or with 3 party products. It can also serve as a standalone controller. Typical areas of application include heating systems, district heating systems, and air conditioning plants for restaurants, shops, offices, and small branch government buildings. The Excel 50 supports standard LonMark Network Variables according to the LonMark Interoperability Guidelines V.3.0. It can serve 22 integrated I/Os and supports peer-topeer communication; thus, in the case of larger-scale applications, several different controllers can be linked and accessed. The system firmware is stored in EPROM or Flash EPROM, located in the application module (a separate module plugged into the controller housing). Flash EPROM allows easy upgrading of the operating system via download. The Excel 50 is available either as a configurable controller with a separate application module for each group of applications (XD50FL-AH03-EN, XD50FCL-HT02-GE, etc.). In this case, a specific application is chosen using the Lizard application selector and then entered as a code number via the MMI or an external interface. The number of LONMARK NVs (typically about 60) is determined by the chosen application; or as a freely programmable controller with an application module, engineered using Honeywell's CARE programming tool, and a maximum of 46 LONMARK NVs.

DESCRIPTION

The Excel 50 controller is available in two housing versions, one with and one without a Man-Machine-Interface (MMI). The MMI version allows buswide access to other controllers. The XI582AH operator interface or the PC-based XI584 operator and service software can be used in conjunction with either version. The housing can be mounted inside a cabinet on a DIN-rail or in a cabinet front door. The Excel 50 has eight analog inputs, four analog outputs, four digital inputs (three of which can be used as totalizers), and six digital outputs. The digital outputs allow the direct drive of 3-position actuators (up to the max. load). The controller can be wired either with screw terminal blocks directly at the housing). Pre-wiring is possible in both cases, and a controller can be replaced without rewiring. The Excel 50 is available in two standalone versions (with or without EPROM) or with different application modules and bus interfaces (see Table 1). Large RAMs provide for increased trending capability. A modem or ISDN terminal adapter can be connected to the serial port of all models equipped with Flash EPROM to allow remote access at up to 38.4 Kbaud. Connection to a Siemens M20 terminal permits wireless communication via GSM. All changeable parts or switches are accessible without opening the housing. Communication capabilities and memory are easily upgraded by replacing application modules.
