Page 96 Chapter 7 - Third Party Protocols
Overview
ION 8000 series meters support DNP 3.0, Modbus RTU and Modbus/TCP
protocols.
While your meter is factory configured to send data (acting as Modbus Slave), it is
not ready to receive data as a Modbus Master until you set up the necessary
framework. The meter is also pre-configured to send DNP 3.0 data to a DNP
Master.
NOTE
Changing the default factory third-party protocol frameworks (or creating new frameworks to enable
receive functionality) is an advanced procedure. Refer to the DNP modules and Modbus modules
descriptions in the
ION Reference , as well as the technical notes Multiport DNP 3.0 and ION Technology,
and Modbus and ION Technology before proceeding.
Most Modbus and DNP modules on the meter are factory pre-set and only require
basic configuration, such as communications setup.
NOTE
Changing these modules from their factory configuration is an advanced setup procedure that requires
an understanding of the protocol, as well as an understanding of the meter’s internal operation. For more
information on your meter and these protocols see the
Common Modbus Registers document and the
ION 8000 Series DNP 3.0 Device Profile .
Communications Protocol Configuration
In order to use the factory Modbus or DNP configuration, you must first assign the
communications channel you want to use. By default, all communications ports
are configured to use the ION protocol. Choose the 3rd-party protocol you want
from the list of available protocols in the Communications module’s Protocol
setup register. See the Communications chapter for instructions.
NOTE
Modbus RTU is available on each of the meter’s communications ports, and multiple ports can
communicate using Modbus simultaneously. Up to three ports can use the DNP 3.00 protocol at any one
time.
