Communications

5.3. Ethernet LAN TCP-IP:

The DCM 200 controller contains a 10 Base T, RJ45 Ethernet port with a Fixed IP address assigned by

the administrator. Additional parameters adjustable are Netmask, Gateway and Primary DNS. The

controller operates as an HTML micro-server for command & control using Microsoft Windows IE7 and

Mozilla’s Firefox internet browsers available on most computers.

Logged data is served as an XML file in response to an HTML request. This feature makes

configuration easy using common Ethernet network browsers already installed on most computers, and

easily supported by local IT departments.

5.4. USB Services

All DCM 200 controllers include a USB port which is used for unformatted datalogging extraction to a

USB “thumb drive”.

5.5. Data Logging

Each enabled input and output is logged by the controller as a user set interval from 1

to 1440 minutes.

The default rate for all data is 60 minutes with a 2400 sample log size. Range is 4 to 600

days. Default maximum is therefore ~40 days of information.

5.3. Control Configuration

The distance between the “Turn ON” and “Turn OFF” setpoints, sets the deadband (hysteresis) response

of an ON/OFF relay, controlled by sensors A,B andC. Not applicable to relays controlled by volume

meters or contact set F.
