Chapter 1 Introduction
This manual explains how to use the PMC-1380-3 Communications Processor. Throughout the
manual the term “PMC-1380-3” generally refers to all models. Differences between models are
indicated with the appropriate model number.
This chapter provides an overview of the PMC-1380-3 Communications Processor and summarizes
many of its key features.
1.1 Overview
The PMC-1380-3 is the ideal embedded equipment for connecting serial devices to an IP-based LAN,
making it possible for SCADA or other applications to access serial devices over a LAN for monitoring
and control applications. The Basic Model (PMC-1380-3-RT) supports the Transparent Ethernet
Gateway function which allows the efficient transfer of serial packets between network-based Master
applications and downstream serial devices via a direct TCP/IP connection, independent of the serial
protocol and operating system. The RTU model (PMC-1380-3-RR) provides Modbus Mastering and
Local Data Logging capabilities with 4GB of non-volatile memory which can support a maximum of
1024 (16x64) Slave IEDs or 64 Slave IEDs per RS-485 port. The RTU model (PMC-1380-3-RR) provides
an additional level of redundancy by supporting data logging of economical downstream Slave IEDs at
pre-defined intervals and implementing data caching for simultaneous access by multiple master
applications via Modbus TCP connections.
The PMC-1380-3 comes with Tx/Rx LEDs for the serial ports on the front panel, and 16 DB9 female
connectors on the rear panel. The LEDs not only indicate the network status but also help to monitor
the communications activities of the attached serial devices. The PMC-1380-3 comes in the standard
19-inch rack mount form factor which makes it easy to install and operate. The PMC-1380-3 has
been specifically designed with industrial automation in mind and therefore provides un-surpassed
performance and reliability under the harshest industrial or commercial environments.
The PMC-1380-3 can be setup through its user-friendly web console. Besides, the PMC-1380-3 has a
LCD display and buttons on its front panel to allow the user to easily view all communications
parameters.
