16.5.2 Hardware self-diagnostic test and initialization setting of the
Q06CCPU-V(-B)
(1) Hardware self-diagnostic test and initialization setting
Starting the C Controller module in the hardware self-diagnostic mode allows the
module to perform the following hardware self-diagnostic tests and initialization
setting. ( (3) in this section)
(a) Hardware self-diagnostic test
(b) Initialization setting
Table 16.16 Hardware self-diagnostic test
Mode Diagnostic item Description
Mode 1
ROM diagnostic test Reads the ROM data and performs a sum check.
Work RAM diagnostic test Checks test data by writing/reading/verifying them on the work RAM.
Battery-backed-up RAM
diagnostic test
Checks test data by writing/reading/verifying them on the battery-backed-
up RAM.
Ethernet diagnostic test Conducts a loopback test of CH1 (10BASE-T/100BASE-TX interface).
Mode 2
CompactFlash card
interface diagnostic test
For the Q06CCPU-V, diagnoses the status of the CompactFlash card
interface.
(This test does not diagnose whether the inserted CompactFlash card is
normal or not. Data are not written to the CompactFlash card.)
For the Q06CCPU-V-B, the test completes normally without diagnosing
the CompactFlash card interface.
Mode 3 RS-232 diagnostic test Conducts the self-loopback test of CH2 (RS-232 interface).
Mode 1+2+3
Diagnostic tests of Mode 1
to Mode 3
Conducts a diagnostic test in the order from Mode 1 to Mode 3.
Table 16.17 Initialization setting
Mode Diagnostic item Description
Default IP setting
Changes the IP address of a C Controller module back to default.
Execution of a script file from the standard ROM is halted.

Standard ROM
initialization
setting
Formats the standard ROM of a C Controller module.
Formatting of the standard ROM is actually effected next time the C
Controller is started after performing the module initialization setting
procedure.
