5-1 Outline of Serial Communications

Introduction
Supported Protocols and Units
120
This section explains how to perform serial communications.
The CX-Simulator can debugs serial communications using (1) actual com-
munications to an external serial communications device using a COM port on
the computer,(2) screen display of send messages, or (3) input/output from/to
a file.
Debugger: Screen display
Virtual Communications Unit

CPU
Note 1. Serial communications cannot be performed when the CX-Simulator is
started and the online connection is made from the CX-Programmer.
2. Refer to 6-3 Serial Communications of CS/CJ Series Programming Manual
for the outline of CS/CJ-series serial communications.
The CX-Simulator supports Host Link (SYSMAC WAY), NT Link, and
No-protocol as a protocol for serial communications. These protocols support
differently depending on a Unit that performs serial communications. The
relationship between serial communications protocols and Units is shown
below.
