Model RZ-100 Distributed Control Module

Primary Control Unit
RZ 100
Date Last Saved: 3/18/2005 12:24:23 PM

Product Name(s): Model RZ-100 Distributed Control Module
Product Description: A general-purpose, graphically programmable controller that resides on a proprietary RZ peer-to-peer network. The controller supports dial-in/dial-out and paging. Expandable to 80 Analog and/or Digital I/O.
Product Application(s): The controller provides custom programmable stand-alone control of general HVAC applications including air-handling units, chillers/boiler/central plant control and distribution systems, data acquisition, and other multi-equipment applications. The RZ-100 can also be used as a 'bridge' controller or router to expand the RZ proprietary network.

Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? Yes
How many total trend values can be stored? Information not provided
What is the controllers role in trending? Trend data is stored in controller RAM until called for archiving by the workstation.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Information not provided
Programming Method(s) All RZ controllers use PerfectHOST for Windows (PHWin) graphical application programming. 'Templates' (logic blocks) are used to develop control sequence logic for all controllers. Application-specific controllers can alternately use pre-developed sequences called 'macros' that are written for specific types of equipment and/or sequences.
Resident vs Non-Resident Program Execution All programming resident and executed at the controller.
Scheduling
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
Other
Resident Energy Management
Energy management algorithms for this controller can be custom programmed
Pre-programmed/built-in algorithms available, and are fully editable using custom programming
Pre-Programmed/built-in with limited editing via template-based programming
Controller is not typically used for energy management functions

Automatical-Dial Alarm Support Available from controller
Does controller perform multiple retries and buffer/store alarm until connection is made? Yes
Are multiple destinations possible? Yes
Upon controller power loss or hardware failure:
Are network communications affected? No

Generate an alarm if backup battery is dead? Information not provided
Upon network or communications failure does controller:
Continue to operate standalone? Yes
Operate with last global settings or user-specified value? N.A.
Do broken network segments continue to communicate within the remaining segment?
(Note: May depend on proper termination of segments for higher speed networks.)
Yes. Controllers on either side of a network break continue to operate peer-to-peer
Does network automatically reconfigure upon restoration? Yes
Does network store 'loss of communications' alarm with time of event? Yes
