6 ASCII Serial Port Operation
6.1 Introduction
You can interact with the SIMPRO-100 Relay
through the front-panel interface or the serial port
interface. This section describes the connections
and commands used with the serial port interface;
the front-panel interface is discussed in
Chapter 5, page 75.
The serial port interface provides an efficient way
to transfer relay settings using the SIMPRO-PC
software. The serial port also provides the only
way to retrieve some of the extensive data that
the relay stores. Use a PC connected to the relay
front-panel serial port to download the following
information:
• Load Profile data
• Motor Start reports
• Motor Start Trend reports
• 15-Cycle Event Reports for fault and
oscillographic analysis
• Sequential Events Recorder (SER) reports for
fault analysis
The first three of these items are described in
Chapter 8, page 111; the last two are discussed
in Chapter 9, page 117.
6.2 You Will Need…
To connect a PC serial port to the relay
front-panel serial port and enter relay commands,
you will need the following:
• Personal computer equipped with one
available EIA-232 serial port
• Communication cable to connect the
computer serial port to the relay serial port
• Terminal emulation software to control the
computer serial port
• SIMPRO-100 Relay
On most newer computers, the connector for the
EIA-232 serial port is a 9-pin D-sub connector.
You can purchase the cable to connect the
computer port to the relay port from Siemens
(part number SIM-232), you can use a
null-modem cable, or you can build your own
cable using the pinouts shown in Figure 6.1,
page 86.
You can use a variety of terminal emulation
programs on your personal computer to
communicate with the SIMPRO-100 Relay.
Examples of PC-based terminal emulation
programs include:
•ProComm Plus™
• Relay Gold™
• Microsoft Windows HyperTerminal™
• Smartcom™
• Crosstalk™
The SIMPRO-PC software also includes a
terminal emulation function. If you use this
package, no additional software is necessary.
