PLC workstation installation process

This article describes installation of PLC workstation using automated installation process. This installation process uses kickstart script and RPM repository for client installation. Installation steps follows.

• Installation preparation

Kickstart script generation

There is script on kernel which generates kickstart script for PLC station being installed. Run

/var/ftp/gen_kickstart <WPID> <LAST_IP_NUM>

WPID - workplace ID

LAST_IP_NUM - last number (octet) from IP address

Example:

We will install workplace A1, IP address will be 10.1.1.25. To generate kickstart script run:

/var/ftp/gen_kickstart a1 25

• PLC client configuration preparation

This is an optional step. You can prepare clients' configuration. You have to copy a configuration file to a directory on kernel. All prepared configurations has to be copied to the directory /usr/local/plc/workstations/XX/etc, where XX is a workplace ID. It is possible to add other files to XX directory and its subdirectories.

Subdirectories:

etc - configuration files

bin - binary files

Content of these directories will overwrite default content from an installation.

• Installation

There are several installation media. Mostly used is an USB flash disk. If there is a problem with a booting from a USB flash, it is possible to boot from a CDROM. For an installation media creation contact PLC support.

Boot from installation media. Boot menu will look similar like this:

Press TAB to edit boot parameters, add these parameters:

gateway=<GATEWAY> netmask=<NETMASK> dns=<DNS> ks=ftp://<KERNEL_IP>/<WPID> ip=<INSTALL_IP>

• <GATEWAY> gateway of your network
• <NETMASK> mask of your network
• <DNS> coma separated list of DNS servers (IP addresses)
• <KERNEL_IP> IP of your PLC kernel
• <WPID> workplace id (name of kick start script)
• <INSTALL_IP> IP address which will be used during installation

Boot.

Rest of installation should be automatic.
