11.1.1 Option Card Diagnostic Errors
Option cards are detected by the 920i 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/D SLOT 4 CHANNEL 1
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 or
try installing the card in a different slot.
• 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, representing cards installed in slots
1–14:
HARDWARE=3,3,2,4,5,0,0,0,0,0,0,0,0,0
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
2 Dual-Channel A/D Card
3 Single-Channel A/D Card
4 Single-Channel Analog Output Card
5 24-Channel Digital I/O Expansion Card
6 Pulse Input Card
7 1 MB Memory Expansion Card
9 DeviceNet Card
10 Profibus Card
11 EtherNet/IP Card
12 Remote I/O Card
14 Custom Card
15 Analog Input Card
16 Generic Anybus Card (ControlNet or
ProfiNet)
17 Dual-Channel Analog Output Card
18 EtherCat 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. Any
slot containing a standard Ethernet card will
return 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. If the card is still not recognized,
try installing it in another slot.
11.1.3 User Program Diagnostic Errors
Faulty user programs can cause critical errors that are
detected by the 920i at power-up. The following error
message is caused by a user program attempting to
divide by zero:
A CRITICAL USER PROGRAM ERROR
HAS BEEN DETECTED
DIVIDE BY ZERO
SYSTEM RESET IS REQUIRED
To recover from this error you can do the following:
• Cycle the indicator power to reset the user
program.
• Correct the iRite program to eliminate the divide
by zero operation. Recompile the program, then
download the corrected program to the indicator.
If technical assistance is required, contact RLWS
technical support.
Note
All A/D scales need to be loaded with a 350
ohm resistor for the iRite start up handler to
run.
Diagnostic Boot Procedure
If a user program causes an error in the start-up
handler, press and hold the setup switch while cycling
power to the 920i to place the indicator in setup mode.
Use iRev 4 monitor mode to send the PCLR command
erase clear the user program.
If the error is still not cleared, perform the following
diagnostic boot procedure.
1. Disconnect power to the 920i.
2. Connect the serial port of a PC with iRev 4
