11.1.1 Option Card Diagnostic Errors
Option cards are detected by the 720i at power-up. If
the current indicator configuration requires an option
card but that card is not detected at power-up, an error
similar to the following is displayed:
HARDWARE CRITICAL TO PROPER OPERATION
WITH CURRENT CONFIGURATION
CANNOT BE FOUND
A second screen is then shown.
SERIAL PORT 7 SLOT 2 CHANNEL 2
Then finally a third screen:
INSTALL HARDWARE OR RECONFIGURE
To recover from this error you can do the following:
• If the option is required, ensure that the card is
properly seated in its slot and cycle the power. If
the card is still not recognized, replace the card.
• Enter setup mode and reconfigure to eliminate
the requirement for the option.
• Go to the VERSION menu and use the Reset
Config softkey (or RESETCONFIGURATION
command) to perform a configuration reset.
Configuration reset returns all configuration
values to their factory defaults.
See Section 11.1.2 below, for information about using
the HARDWARE serial command to verify that
installed cards are recognized.
11.1.2 Using the HARDWARE Command
The HARDWARE serial command can be issued to
verify that all installed cards are recognized by the
system. The HARDWARE command returns a string of
card type codes. The first digit represents the
single-channel A/D of the
720i ; the second digit
represents the card, if any, installed in the expansion
slot: HARDWARE=3,4
Table 11-2 lists the card codes returned by the
HARDWARE command.
Table 11-2. HARDWARE Command Option Card Codes
Code Card Type
0 No card installed
1 Dual-Channel Serial Expansion Card
3 Single-Channel A/D
4 Analog Output Card
5 24-Channel Digital I/O Expansion Card
9 DeviceNet Card
10 Profibus Card
11 EtherNet/IP Card
12 Remote I/O Card
14 Custom Card
16 ControlNet Card
Note
Code 11 is returned only by the EtherNet/IP
card. The standard 10M/100Mbps Ethernet
card does not return a card type code. The
standard Ethernet card returns a value of 0
on the HARDWARE command.
If an installed card is not recognized (HARDWARE
command returns a code of
0 for that slot), ensure that
the card is seated properly. Reinstall the card, if
necessary, then cycle the indicator power to read the
configuration again.
11.1.3 Diagnostic Boot Procedure
If a persistent error occurs that cannot be cleared with
the RESETCONFIGURATION command, perform the
following diagnostic boot procedure.
1. Disconnect power to the 720i .
2. Connect the serial port of a PC with Revolution
III installed to port 2 of the 720i .
3. Open the indicator enclosure and place a
j u m p e r a c r o s s t h e b o o t m o d e p i n s ( s e e
Figure 2-3 on page 9).
4. Power up the 720i . The indicator will stall at
the diagnostic monitor.
5. Start Revolution III and enter monitor mode,
then type BOOT .
6. Place jumper J9 across both pins to enable
setup mode.
7. Press MENU , then select Configuration to enter
setup mode.
8. Remove the jumper from SW1.
9. From monitor mode, enter the
RESETCONFIGURATION command.
11.1.4 Onboard Diagnostic LEDs
The 720i CPU board provides a number of LEDs that
m a y b e u s e f u l f o r m o n i t o r i n g o r d i a g n o s i n g
communications or other functions. These LEDs are
listed in Table 11-3.
