2.4 Automatic update of TC, Servo and Spindle
2.4.1 Automatic update Overview
All TCs in a system, System TCs as well as Spindle TCs, must use the same TC System Software
version in order to function properly. There are several methods to verify that this is the case for all TCs in
a system. The TCs themselves checks for version conflicts at start up and indicate this using the display
on their front and ToolsTalk PowerMACS has several forms that can be used for the same purpose.
As from version 7.3.0 it is no longer necessary to use the TTPM to download new software to a replaced
TC in a system. When replacing a TC in a system the correct TC software would be downloaded
automatically to the replaced TC from the System TC or the Backup TC (TC2).The software that is
downloaded consists of the following:
ï‚· The TC application software
ï‚· The Servo application software
ï‚· The Spindle application software
The automatic download function makes it possible to replace any TC in a system with a TC that has
different software loaded, and to automatically update the software in that TC with the same as the rest of
the system.
2.4.2 General function
The purpose of the Automatic Download function is to ensure that all TC in a system has the same
software version after a TC has been replaced. When a new TC is inserted in a system the version
handling function detects if the TC has a different software version. If the software in the replaced TC
supports Automatic Download (version 7.3.0 or newer) the download of new software is started when an
operator initiate it through the replaced TC:s panel.
The Automatic Download function is always enabled in systems that support it and consist of two or more
TCs. Normally all software updates is initiated by the System TC that uses its own software to update all
other TC:s in the system, if however the System TC is replaced it will be updated with the software from
the Backup TC (TC2) before any other TC is updated.
Before the replaced TC is inserted in the system it must be prepared by an operator to have the right TC
number and the right type (P or S). When a replaced TC with a different software version is detected the
following text appears on the TC panel:
