## MP Error Information

An MP error is associated with the CMM electronics. The error numbers are categorized into the following groups:

Group | Range | Description
MP | 1-199 | Diagnostic errors
TempComp | 200-299 | Temperature compensation
MP | 300-399 | Stand-alone operation using MP front panel on MP-30/35
MP | 500-599 | MP power-up
MP | 600-699 | DCC power-up
RCU | 700-799 | RCU power-up

MP error numbers are typically displayed on the fourth row of the XYZ Display at the PC. XYZ Display is a monitor that can be displayed as a window in MeasureMax+ and STI. On MaxLite systems, it is displayed in the lower-right corner. If you have an MP-30/35 system with a front panel, then the error is also shown in the W-axis display of the MP front panel.

For memory errors, additional information is shown in the Z-axis of the XYZ Display (or MP front panel, if available). The hexadecimal address and bit information allows the Giddings & Lewis service representative to diagnose the source of the error. Memory errors are displayed in the format "AAAAA C", where "AAAAA" is the address and "C" is the bit.

- In the case of MP RAM, "C" is the bit location where the error occurred. For MP ROM, DCC RAM and ROM errors, "C" is the byte where the error occurred.

- If the error number is 500-599, the address and bit information pertains to the MP CPU board.

- If the error number is 600-699, the address and bit (or chip) information pertains to the DCC board.

If error MP-160 occurs during power-up, check the DCC board LED, cycle power and watch the LED. A sequence of characters flashes on the LED as testing takes place. Each character represents a test of a specific system component or of communication between components. If one of these tests fails, the character representing that test remains on the LED. The DCC Led sequence is:

A | Testing shared RAM memory cells
B | Testing DCC to MP interrupt
C | Testing MP interrupt acknowledge
D | Testing MP to DCC interrupt
E | Testing DCC ROM and RAM
F | All tests passed - waiting for first MP interrupt

If the DCC board fails after the system is on, error MP-060 or MP-151 occurs. These errors indicate that the MP is unable to communicate with the DCC board. Check the DCC board LED for the following numbers:

1 | 32 ms since last D/A update
2 | 32 ms since last MP update
3 | DCC to MP interrupt not acknowledged for 32 ms
8 | System running normally
9 | Waiting for initial MP shared RAM sync-up

On the DCC board LED, a decimal point before the error number means the CPU is inactive. A decimal point after the error number means the hardware detected a failure to update D/A for 32 milliseconds.

For MP power-up failures (error number 500-599), it may not be able to transmit an error message to the computer. On an MP-30/35 system with a front panel, the error is shown in the W-axis display of the MP front panel. On an SMP system, the error is shown in the diagnostic LED.
