EXCEL 50/100/500/600/800 SYSTEM OVERVIEW General Excel 50/500/800 controllers support both LONWORKS communication and the Honeywell proprietary C-Bus communication. All LONWORKS-related information is described in the LONWORKS Mechanism document (EN0B-0270GE51). Excel 50/100/500/600/800 is a control and monitoring system specially designed for use in buildings. These Excel controllers use the latest Direct Digital Control (DDC) technology. Excel 50/500/800 controllers are also capable

OVERVIEW EXCEL 50/100/500/600/800 • Annual programs • The "TODAY" function • Special day list Daily programs are used to create a weekly program. The annual program is created automatically by multiplying the weekly program and then incorporating additional daily programs. The "TODAY" function enables you to have a direct influence on the switching program. This function enables you to allocate a setpoint or status to the selected datapoints for a defined time period. This action does

DATAPOINTS EXCEL 50/100/500/600/800 Flexible Datapoints Flexible datapoints allow the control of more than one physical output with one datapoint. There are three subordinate types of flexible datapoints: • Pulse 2 • Multi-stage • Feedback. Pulse 2 flexible datapoint A pulse 2 datapoint allows to pulse two digital outputs (e.g. relays). When activated (e.g. set to “on”), Pulse 2 triggers one of the digital outputs, and when deactivated, Pulse 2 triggers the other digital output.

EXCEL 50/100/500/600/800 ATTRIBUTES Each datapoint type has associated with it various parameters which allow the user to set, e.g., the user address, the level of access protection, alarm behavior, and other options. These parameters are called attributes. Each attribute performs a specific function related to the datapoint. A complete list of datapoint types and their attributes appears in Table 17 through Table 19. Not all attributes are available for every datapoint type. Point re

ATTRIBUTES EXCEL 50/100/500/600/800 Active State (prior to V2.04.x) The attribute "Active State" defines when a digital input/output is active. NOTE: The "Active State" attribute does not reflect the current condition of a digital datapoint. NOTE: This is not applicable to digital inputs in applications designed for con- trollers using V2.04.xx firmware or higher. In such applications, this attribute is fixed at 1, and the new attribute "Normally Open/Normally Closed" (NO/NC) is activ

EXCEL 50/100/500/600/800 ATTRIBUTES In the datapoint description, the alarms can be influenced using the functions described below (see also Table 6 on page 17). Alarm type For each datapoint in the datapoint description, the user can determine whether the signals generated are to be treated as critical or non-critical alarm. Alarm delay An alarm signal can be delayed by entering an alarm delay time. An alarm signal will be generated only if an alarm continues uninterrupted during th
