B.6 Communications
USB Services
All Ammonia Analyzers include a USB port which is used for three purposes:
1. Upload of logged data in XML format to a notebook PC or a PDA operating as a USB host.
2. Download of View-Configuration Sets into the analyzer.
3. Upload of the current controller configuration from the analyzer to support generation of View-
Configuration Sets and for controller cloning.
Configuration-View sets:
Controllers with the ‘
LB
’ Ethernet option are loaded with the ammonia view. It is selected when the
controller is manufactured to be the ‘as shipped’ view-configuration.
LAN TCP-IP:
The
LB
analyzer option adds a 10 Base T, RJ45 Ethernet port with a user assigned static IP. The controller
operates as an HTML micro-server for command & control using IE7 and Mozilla’s Firefox browsers.
Logged data is served as an XML file in response to an HTML request.
Modem:
The
RM
controller option adds a 57,600 baud micro modem that provides a PPP connection so that remote
users can browse the controller. AJAX supports the same graphical View interface used by on-site users.
B.7 Data Logging
Each enabled input and output is logged by the analyzer as a user set interval from 5 to 1440 minutes.
Each I/O can be independently logged at its own rate. The default rate for all I/O is 60 minutes with a 600
sample log size. Sensors log minimum, maximum and average. Water meters log volume. Contact sets log
time ON. Power relays and valves, log ON time in seconds.
Alarms are time & date stamped. The last 25 controller activities are time and date stamped with the user
ID.
Note:
Data logging of relay ON time stops when AC fuse fails since without a fuse a relay
can’t power ON a valve or solenoid
