1. OVERVIEW
When a PC running Laurel's XLog datalogging software is connected to Laureate meters
and transmitters, readings can be written to disk in the form of text files or MS Excel files.
User settable parameters include the logging time interval in seconds, header data with or
without time and date, and password protection for the setup files. Readings can also be
displayed on the PC monitor the form of up to 64 simulated panel meters in up to 4 groups
(or windows) of up to 16 meters each. The simulated meters can display actual meter
readings or virtual readings, which are mathematical combinations or actual readings. The
on-screen position and appearance of the simulated meters is user selectable to achieve
meaningful groupings.
The physical data connection between the PC and the instruments can be via Ethernet,
USB, RS485 or RS232. Please see the communication ordering options listed below. With
an Ethernet connection, remote real-time data can be viewed and logged over the Internet.
User-selectable communication protocols are Modbus RTU, Modbus ASCII, and Custom
ASCII. The latter is simpler than the Modbus protocol and is recommended when all instru-
ments on the same data line are Laureates. All of the listed protocols can be used with all
the listed physical data connections.
Serial Communication Ordering Options for Panel Meters:
0........ None
1........ RS232 (single RJ11 jack)
2........ RS485 (dual RJ11 jack)
4........ RS485 (dual RJ45 jack)
5........ USB (type B jack)
6........ USB-to-RS485 converter (type B jack for USB plus RJ11 jack for RS485)
7........ Ethernet (RJ45 jack)
8........ Ethernet-to-RS485 converter (RJ45 jack for Ethernet plus RJ11 jack for RS485)
Serial Communication Ordering Options for DIN Rail Mounted Transmitters:
LT ..... Main board with RS232 or RS485 communications (jumper selectable)
LTE ... Main board with Ethernet communications
Note that LT and LTE transmitters also provide an isolated 4-20 mA or 0-10V analog
output and dual solid state relays as a standard feature.
Ethernet-to-RS485 Converter & Device Server, DIN Rail Mounted:
LTNET485 ...Ethernet-to-RS485 converter (RJ45 jack for Ethernet, RJ11 jack for
RS485, screw terminals for RS485)
