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 (Auto)
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 PWA 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
0 Other
1 Block Configuration Error: A feature in CYCLE_SEL is set that is not supported by
CYCLE_TYPE.
3 Simulate Active: This indicates that the simulation jumper is in place. This is not an
indication that the I/O blocks are using simulated data.
7 Input failure/process variable has bad status
9 Memory 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.
