Block Errors
Table 3-3 lists conditions reported in the BLOCK_ERR parameter.
Table 3-3. BLOCK_ERR
Conditions .
Modes
The resource block supports two modes of operation as defined by the
MODE_BLK parameter:
Automatic (Aut o)
The block is processing its normal background memory checks.
83 ADVISE_ALM Alarm indicating advisory alarms. These conditions do not have a direct impact on the
process or device integrity.
84 HEALTH_INDEX Parameter representing the overall health of the device, 100 being perfect and 1 being
non-functioning. The value will be set based on the active PW A alarms in accordance with the
requirements stated in “Device Alerts and Health Index PlantWeb Implementation Rules”.
Each device may implement its own unique mapping between the PWA parameters and
HEALTH_INDEX although a default mapping will be available based on the following rules.
HEALTH_INDEX will be set based on the highest priority PWA *_ACTIVE bit as follows:
FAILED_ACTIVE: 0 to 31 - HEALTH_INDEX = 10
MAINT_ACTIVE: 29 to 31 - HEALTH_INDEX = 20
MAINT_ACTIVE: 26 to 28 - HEALTH_INDEX = 30
MAINT_ACTIVE: 19 to 25 - HEALTH_INDEX = 40
MAINT_ACTIVE: 10 to 16 - HEALTH_INDEX = 50
MAINT_ACTIVE: 5 to 9 - HEALTH_INDEX = 60
MAINT_ACTIVE: 0 to 4 - HEALTH_INDEX = 70
ADVISE_ACTIVE: 16 to 31 - HEALTH_INDEX = 80
ADVISE_ACTIVE: 0 to 15 - HEALTH_INDEX = 90
NONE - HEALTH_INDEX = 100
85 PWA_SIMULATE Allows direct writes to the PlantWeb Alert "ACTIVE" parameters and
RB.DETAILED_STATUS. The simulate jumper must be "ON' and the SIMULATE_ STATE
must be "Jumper on, simulation allowed" before PWA_SIMULATE can be active.

Number Parameter Description
Number Name and Description
0Other
1Block Configuration Error: A feature in CYCLE_SEL is set that is not supported by
CYCLE_TYPE.
3Simulate Active: This indicates that the simulation jumper is in place. This is not an
indication that the I/O blocks are using simulated data.
7Input failure/process variable has bad status
9Memory Failure: A memory failure has occurred in FLASH, RAM, or EEPROM
memory.
10 Lost Static Data: Static data that is stored in non-volatile memory
has been lost.
11 Lost NV Data: Non-volatile data that is stored in non-volatile memory
has been lost.
13 Device Needs Maintenance Now
14 Power Up: The device was just powered-up.
15 OOS: The actual mode is out of service.
