Step 3. Examine registers 82/1082 and 83/1083 (and 86/1086 and 87/1087) for the
number of CRC and format errors received on the UDC module (and PMI
Regulator). If either of these values is incrementing, it indicates a problem.
Step 4. Examine register 88/1088 for the status of the fiber-optic ports on the UDC
module. If the operating systems are loaded and no tasks are running, the
lower byte should be equal to xx03H (UDC module and PMI Regulator are
exchanging data). The upper byte should be equal to 02xxH (communication
between the UDC module and PMI Regulator is unsynchronized). Note that
“xx” in the byte descriptions indicates “not used.”
Step 5. Examine register 89/1089 for the number of messages transmitted by the
UDC module. Over time, this 16-bit value should increase to its maximum
value (32767) and then roll over.
4.7.8.2 Testing Flex I/O Registers
This section describes how to test the Flex I/O registers if used in your system. Use
the AutoMax Programming Executive software I/O Monitor function to display the Flex
I/O registers in the format listed in table 4.2.
Display these registers in decimal format if they are used for analog I/O. Display them
in binary format if they are used for digital I/O.
