Data Manager
This chapter describes how the LumaSMART
®
Data Manager stores operating data and how to retrieve that data.
The Data Manager averages six temperature measurements and saves that average into a data report once every
minute. It also sends temperature measurements every 10 seconds to any host computer that is connected to the
LumaSMART controller’s RS232 or RS485 port.
To communicate with the LumaSMART controller, the host computer must run a terminal emulation program
(such as HyperTerminal). The terminal emulation program receives, displays, and saves the real-time temperature
measurements and data reports to a file.
The Data Manager maintains a limited amount of memory available for data storage and will erase the oldest data
reports to make room for new data when room runs out. To permanently save data reports, export them from the
LumaSMART controller through the interface port or by exporting them onto a thumb drive via the USB port (See
Section 5.2.5,
, for more information on exporting via USB).
Note:

communicate with the Data Manager.
9.1
Data Report Content
Data reports contain the following:
•
Date and Time of temperature reading
•
Measured temperature values of each active channel (1 through 16)
•
State (energized or released) of all relays
9.2
Data Retrieval
Each line of a retrieved data report contains a string of characters with the following information:
•
Date and Time of temperature reading
•
Measured temperature values of each active channel (1 through 16)
•
State (energized or released) of all relays, starting with the System Status Relay, then Relay 1 through 16.
A 0 indicates a Deenergized relay, a 1 indicates an energized relay that the system status relay is in its
normal non-fault state, and 10100010000100100 shows relays 2, 6, 11, and 14 str energized
