Operation
5.0 Networking and Communication
5.1 Introduction
The TriStar MPPT 150V provides several communication options. The TriStar MPPT 150V uses a
proprietary protocol for the MeterBus
network and the non-proprietary open standard MODBUS
TM
and MODBUS TCP/IP
protocols for RS-232, EIA-485, and ethernet networks. Additionally, HTTP,
TM
SMTP, and SNMP are supported for web page, email, and network message support.
Morningstar's MSView
PC software provides system monitoring and logging capabilities via RS-
TM
232, EIA-485, and Ethernet. MSView
PC software is available for free on our website at:
TM
http://www.morningstarcorp.com
Further, hardware and third party software that supports the MODBUS
communicate with a TriStar MPPT 150V.
Multiple communication ports can be used simultaneously. For example, a TriStar MPPT 150V may
be connected to a MeterBus
network for on-site system metering, connected to the internet for
TM
remote monitoring, and connected to an EIA-485 network to bridge data from other controllers in the
system to an internet connection. Note that the RS-232 and EIA-485 connections share hardware and
therefore cannot be used simultaneously.
Table 5-1 below provides a summary of morningstarcorp.com/supported features for each communi-
cation interface.
