Tool number table checksum error
TOOL NUMBER TABLE CHECKSUM ERROR
THE INFORMATION CREATED WHEN A TOOL
NUMBER IS PROGRAMMED WAS CORRUPTED.
GO BACK AND REVIEW THE TOOL NUMBER
PROGRAM. MAKE CHANGES IF NECESSARY,
THEN RELOAD THE TOOL NUMBER.
Problem: The checksum for the tool number that is computed when the tool
number is loaded does not match the checksum computed and stored
the last time the tool number was modified. This message will appear
when you load a tool number if the checksums do not match.
DiPro creates a checksum for a tool number to check that the data
stored in memory for the tool is the same as the data that comes out of
memory when you load the tool number. The checksum calculated
when data went into memory must be the same as the one calculated
when the data is loaded. Here is a simple way to think of a checksum:
A group takes a bus to a game. The driver counts everybody who gets
off the bus (the checksum). After the game, he counts everybody who
gets on the bus. He does not leave until he counts the same number
getting on as got off (the checksums must match).
Remedy: The checksums may not match if DiPro 1500 is turned off while in the
middle of programming or adjusting settings for a tool. It will also
happen if the stored tool number settings get damaged due to an
internal DiPro malfunction.
If the problem was caused because the system was turned off while in
Program or Run modes, perform these steps:
1) Press the RESET key to clear the fault message.
2) Go to Program mode, and select "Program/load tool numbers".
3) Select the tool number in question from the tool number display.
4) Select "Modify the tool information" from the next display.
5) Select "Set sensors" from the next display.
6) Press RESET. DiPro will create a new checksum for the tool number.
7) Select the tool number again, bring up the display of sensors, and
verify that all settings are correct.
8) Reload the tool number. You should not get this fault message.
If the problem is due to a system malfunction, the tool number settings
will have to be created again from scratch. If this happens more than
once, contact Data Instruments for assistance.
