Bradley Smoker PLC-5 user manual Editing the Bootptab Configuration File

Communicating with Devices on an Ethernet Network 11-7

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.

Editing the BOOTPTAB Configuration File

IMPORTANT

Be sure you know the Ethernet hardware address of the module. You will enter it in this 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:

plc5name: tc=defaults5E:ip=aa.bb.cc.dd:ha=0000BC1Cxxyy

IMPORTANT

Use this line as the configuration template for Ethernet PLC-5 controllers.

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.
