Table 10.7 Summary of Configuration Errors
Problem/Fault
Probable Cause
Recommended Action
Name of parameters are not
visible
Missing or incorrect version of device
description file on host computer.
1. Check path to device description.
2. Load correct version of DD.
Unable to write successfully
to MODE_BLK of any block.
Mode not supported in TARGET and/or
PERMITTED modes for the given block.
• Verify that the mode being written is supported by the block.
• If writing TARGET mode only, then the desired mode must already be set in
the PERMITTED field.
• If writing the whole MODE_BLK record, then the mode set in TARGET must
also be set in the PERMITTED field. Other modes may also be set in the
PERMITTED field, but target mode must be set.
Unable to write to a
parameter
1. Parameter is read-only.
1. None
2. Sub-index of the parameter is read-only.
Some parameters have fields that are not
writable individually (such as MODE_BLK.
ACTUAL).
2. None
3. Write-locking is active. Resource block
parameter WRITE_LOCK value is 2.
3. Remove write protect jumper (see Subsection 6.5)
4. Corresponding block is in the wrong
mode. Some parameters can only be
written to in OOS mode only, or in OOS or
manual modes.
4. Write valid mode to MODE_BLK parameter of block (OOS or MAN
modes). See Mode Restricted Writes to Parameters in Sub-sections 8.6
and 8.7.
5. Data written to the parameter is out of the
valid range for that parameter.
5. Write valid range values to parameter.
Unable to change resource
block to auto mode
1. The second element of BLOCK_TEST is
not zero.
1. Write all zeroes to the second element of the BLOCK_TEST parameter.
2. Resource block is in OOS mode.
2. Write auto mode to MODE_BLK.TARGET of the resource block.
3. The second element of BLOCK_TEST is
non-zero.
3. Write all zeroes to the second element of the BLOCK_TEST parameter.
4. A configuration error occurred in the
block.
4. Find and correct any configurable parameter outside its valid range. See
Clearing Block Configuration Errors in Sub-section 10.6.
Unable to change analog
output block from OOS
mode
1. The block has not been configured to
execute. It is neither in the function block
schedule in the system management
information base, nor is it linked to another
executing block via the next block to execute
field in the block record (relative parameter
index).
1. Build and download an execution schedule for the block including links to
and from AO block with other function blocks.
2. Resource block is in OOS mode.
2. Write auto mode to MODE_BLK of resource block.
3. Block configuration error.
3. a. Check the parameters SHED_OPT and CHANNEL. All values must be
non-zero.
b. BLOCK_ERR for bit 1 set. If set, check all configurable parameters for
possible invalid values. See Clearing Block Configuration Errors in Sub-
section 10.6.
4. The second element of BLOCK_TEST is
not zero.
4. Write all zeroes to the second element of the BLOCK_TEST parameter.
