Communicating with Devices on an Ethernet Network 11-7
Editing the BOOTPTAB Configuration File
You must edit the BOOTPTAB file, which is an ASCII text file, to include the
name, IP address, and hardware address for each Ethernet PLC-5 controller
you want the server to boot. To edit this file:
1. Open the
BOOTPTAB file using a text editor.
• The file contains lines that look like this:
#Default string for each type of Ethernet client
defaults5E: ht=1:vm=rfc1048
These are the default parameters for Ethernet PLC-5 controllers and
must always precede the client lines in the
BOOTPTAB file.
• The file also contains a line that looks like this:
1. Make one copy of the Ethernet PLC-5 controller template for every
Ethernet PLC-5 controller in your system.
2. Edit each copy of the template as follows:
A. Replace
plc5name with the name of the Ethernet PLC-5 controller.
Use only letters and numbers; do not use underscores.
B. Replace
aa.bb.cc.dd with the IP address to be assigned to the
controller.
IMPORTANT
If BOOTP is disabled, or no BOOTP server exists on the
network, you must use PLC-5 programming software to
enter/change the IP address for each controller.
IMPORTANT
Be sure you know the Ethernet hardware address of the
module. You will enter it in this file.
IMPORTANT
Use this line as the configuration template for Ethernet
PLC-5 controllers.
plc5name: tc=defaults5E:ip=aa.bb.cc.dd:ha=0000BC1Cxxyy
