Product Name(s): MACH-ProCom
Product Description: The MACH-ProCom is a 32-bit based BACnet building controller. The MACH-ProCom controller database allows users to define up to 160 universal I/O on a single address.
Product Application(s): The MACH-ProCom is used as a network communications Router and for centralized high-point count applications where unrestricted programming and full data acquisition are required. The MACH-ProCom is suited for installation in larger mechanical rooms containing several air handlers, boilers, chillers, and other environmental control devices. The MACH-ProCom provides high speed 10/100 Ethernet, SMART-Net communications, expandable I/O, and protocol support for BACnet, RCP, SMTP, and Modbus RTU and TCP (both master and slave).

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? 96 Trend Logs, each one stores 512
samples and up to 6 points.
Values recorded at user defined
intervals. BACnet trend logs are supported.
What is the controllers role in trending? To gather data for use in analyzing system performance
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? Overwrite data
Programming Method(s) Line code programming language (Control-BASIC)
Resident vs Non-Resident Program Execution Resident, programs are executed on each panel
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.
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
Specific Pre-Programmed Algorithms Available
None (custom programming only)
None (not applicable)
Optimal Start/Optimal Stop
Peak Demand Limiting/Load Shedding
Economizer (enthalpy, dry-bulb, CO2, modulating/2-position, etc.)
Additional Energy Management functions are resident at SI
Additional Programming Functions Customizable open ended programming system
DDC Loops (P, PI, PID) 64 DDC Loops - Standard P, PI, or PID controllers for closed loop control.
BACnet loops are supported.
Automatic PID Tuning Feature Yes, through Control-BASIC functions
Automatical-Dial Alarm Support Yes, through Control-BASIC dial-alarm statements: APDIAL - uses the TAP protocol system for alpha-numeric pagers, PHONE - emulates key strokes on telephone for numeric pagers, EMAIL - send alarm notifications to specified email addresses.
Does controller perform multiple retries and buffer/store alarm until connection is made? No, alarm database collects all alarms and are visible through RC-Studio software
Are multiple destinations possible? Yes, each operator workstation can display all alarams in the system. Each operator workstation can be individually configured to display certain alarms.
Upon controller power loss or hardware failure:
Are network communications affected? Depends on nature of hardware failure, typically not affected by power loss
Is loss recognized on/by the network and alarm reported? Controller offline alarms are generated in RC-Studio
DO and AO response?
Outputs fail to a user pre-specified position
Outputs fail to a normal (unpowered) position
Outputs fail to last position
Other Outputs turn off when unpowered, when power restored, return to programmed position
Volatile memory functions?
Retained for life of backup battery
Upon restoration of power does the controller:
Auto-reboot without operator intervention? Yes
Automatically reset/synchronize the clock? Yes
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? No
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.)
Does network automatically reconfigure upon restoration? Yes
Does network store 'loss of communications' alarm with time of event? Yes
