About this Manual, Continued
This manual contains the following sections.
Section 1
introduces the hardware and software functions of the Serial Communications Boards and
the Serial Communications Units, including the communications modes, system configurations, and
specifications.
Section 2
describes the components of the Serial Communications Boards and the Serial Communi-
cations Units, the settings required for operation, and the memory allocated in the I/O memory of the
CPU Unit for controlling and monitoring communications.
Section 3
describes how to mounting the Serial Communications Boards and Serial Communications
Units, and how to connect the ports to external devices.
Section 4
describes the procedure and other information required to use Host Link communications.
Section 5
describes the procedure and other information required to use protocol macros.
Section 6
provides an overview of the Serial Gateway, information on I/O memory allocations, and
procedures for using the functions. Information on protocol conversion, routing table requirements, and
communications frames is also provided. The Serial Gateway can be used only for Unit Ver. 1.2 or
later.
Section 7
describes the procedure and other information required to use the no-protocol mode. This
mode is supported for Unit Ver. 1.2 or later only.
Section 8

ble Terminals.
Section 9
describes the procedure and other information required to use Modbus-RTU slave mode.
Section 10
describes the procedure and other information required to conduct loopback test to check
the serial ports.
Section 11
describes the troubleshooting and maintenance procedures for the Serial Communications
Boards and the Serial Communications Units.
Appendix A
to
Appendix Q
