1: GENERAL INFORMATION
Introduction
This chapter describes an overview of the FC6A Series MicroSmart, which is equipped with a communication interface.
Description
The FC6A Series MicroSmart can perform RS232C and RS485 communication using serial port 1. The communication ports can be
expanded by using communication cartridges to allow for multiple instances of RS232C and RS485 communication. The Ethernet
port is standard equipment to enable communication using Ethernet. Also, the Ethernet port can be expanded by using an HMI
module. The CAN J1939 All-in-One Type is equipped with a CAN port to enable J1939 communication.
Communication Interfaces
An overview and the specifications of the communication interfaces are shown below.
USB Port
Maintenance communication can be performed by using this port to connect to a computer.
Serial Port 1
This port can be used to communicate with RS232C/RS485 communication-compatible external devices such as computers,
operator interfaces, and printers.
Maintenance communication, user communication, Modbus RTU communication (master/slave), and data link communication
(master station/slave station) are possible.
Ethernet Port 1
This port can be used to communicate with Ethernet communication-compatible external devices such as computers and operator
interfaces.
This port has eight connections that can be used with Ethernet communication. Each of these connections can simultaneously use
a different communication protocol. Each connection can be configured for maintenance communication (server), user
communication (server/client), or Modbus TCP communication (server/client).
