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.

6. Subindex used is invalid for that

parameter

6. Enter valid subindex for 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.

AO block is in the

correct mode but

does not seem to be

operating

1. Simulation active.

1. Disable simulation. See Sub-section

10.8 for procedure.

2. The block has not been configured to

execute. It is neither in the function

block schedule in the system manage-

ment information base, nor is it linked

to another executing block via the next

block to execute field in the block record

(relative parameter index 0).

2. Build and download an execution

schedule for the block including links

to and from AO block with other

function blocks.

3. The second element of BLOCK_TEST is

not zero.

3. Write all zeroes to the second

element of the BLOCK_TEST

parameter.
