DL-40JANUS-DCA/DCV manual (d0114)
Page 3
The DL-40JANUS is an intelligent meter with a hierarchical
software structure designed for easy programming and opera-
tion, as shown below in the software logic tree.
After the meter has been powered up, the four
digits light up for three seconds and then settle to
the operational display indicating the input signal.
15 Second
Program Timeout
The meter has a 15 second
program timeout. If no buttons
are pressed for 15 seconds, at
any stage of the programming
sequence the meter will exit the
programming mode and return
to the operational display. Any
program changes that were
made prior to pressing the
P
button in the preceding step
will not be saved.

Texmate’s Modbus RTU RS-485 module provides
half-duplex, serial communication to PLC, SCADA and
other systems for monitoring and control of the meter’s
functions. The meter functions as a slave.
The RS485 module takes the place of the Analog Output
module, so it is not possible to have both Analog
Output and RS-485 communication. Programming and
operation of the meter are done via a different menu
system, or Software Logic Tree, that is accessed through
the front panel push buttons, see below.
