BPS Command

The BPS command has the form:

BPS

This command causes the current serial port data rate to be displayed. A typical BPS command is shown below:

> bps

bps = 9600

CHBPS Command

The CHBPS command has the form:

CHBPS { 9600 2400 1200 300 }

where one of the data rate selection values is entered

This command is used to change the data rate on the serial port of the Ethernet Inter- face. Any input or output from the serial port after the command has been successfully entered will use the modified data rate. The data rate remains in effect until it is again explicitly changed or until the Ethernet Interface is restarted. The default data rate is 9600 bps.

A typical CHBPS command is shown below:

=chbps 1200 bps = 1200

If the output device attached to the serial port is not set to the new data rate, the BPS command message will be lost or garbled.

CHDATE Command

(Not recommended if the PLC CPU is configured properly.)

The CHDATE command has the form:

CHDATE <DD-MMM-YYYY>

(an example date is: 01-JAN-1989)

This command is used to change the system date to the date specified in the command. No date earlier than Jan 1, 1989 may be entered. If an invalid date is entered, the current date is not changed. Date changes remain in effect until the Ethernet Interface is pow- ered-up or restarted.

A typical CHDATE command is shown below:

=chdate 24-MAY-1996 Date = 24-MAY-1996
