Suggestions and Precautions
Section 7-6
In the case that the programs are not consistent, the Check Project Options
Window will be displayed. Please be aware that if the current project is re-
opened, the backup copy of the project will be overwritten. It is therefore nec-
essary to determine which copy of the programs to use before re-connecting
Motion Perfect.
To investigate the inconsistency further, a Terminal Window can be opened
off-line and the programs on the MC Unit can be listed. Any computer-based
editor or word processor can be used to examine the computer backup
project file copy of the programs. In this way, the location of the uncorrupted
or latest version of the programs can be identified. The correct program can
be imported to the project by using the Load Program File option of the
Project Menu.
The computer project copy of a program is updated during a Motion Perfect
development session whenever an edit session for the program is closed.
Retrieving Backup
If you want to abandon changes made during a development session and
reload the backup copy made at the start of the session, then select Revert to
Backup from the Project Menu.
Downloading Firmware
The MC Unit has Flash memory for storage of both user programs and the
system software. From Motion Perfect it is possible to upgrade the software to
a newer version using a system file.
Select the 'Load System Software' option from the controller menu and a
warning dialog will be presented to ensure the current project has been saved
the user wishes to continue. Press OK and select the file which needs to be
loaded.
!Caution
Do not download any firmware to the MC Unit that has not been distributed by
OMRON or that has not been authorized and approved by OMRON for down-
loading into the MCW151 series. Failure to do so may result in permanent or
temporary malfunction of the Unit or unexpected behaviour.
Downloading will take several minutes, depending on the speed of the per-
sonal computer. When the download is complete, a checksum is performed to
ensure that the download process was successful, and a confirmation screen
will be presented to store the software into Flash memory. The controller will
take a few moments to store the software.
!WARNING
During the process of storing the software into Flash memory the power must
NEVER be interrupted. If power is interrupted the MC Unit may disfunction
and has to be returned to OMRON for repair.
If the storing has been completed the unit is back to normal operation. At this
point you can check the controller configuration to confirm the new software
version.
