1. Introduction
The I-7000 series is a family of network data acquisition and
control modules, providing analog-to-digital, digital-to-analog,
digital input/output, timer/counter and other functions. The
modules can be remotely controlled using a set of commands,
which we call the DCON protocol. Communication between
the module and the host is in ASCII format via an RS-485 bi-
directional serial bus standard. Baud Rates are software
programmable and transmission speeds of up to 115.2 Kbps
can be selected.
The functionality of the M-7000 series is the same as the I-
7000 series, with the exception that the M-7000 series offers
extended support for the Modbus RTU protocol.
Some M-7000 modules feature
a new design for the frame
ground and INIT switch as
shown in the figure (rear
view). The frame ground
provides enhanced static
protection (ESD) abilities and
ensures the module is more
reliable. The INIT switch
allows easier access to INIT
mode. Please refer to Sections
A.1 and A.3 for more details.
The M-7084 supports up counting, up-down counting, pulse
direction counting, quadrature counting and frequency
measurement.
