Diagnostics

In addition to the BLOCK_ERR parameters, more detailed information on the device status can be obtained via DETAILED_STATUS. Table 5.3 lists potential errors and possible corrective actions for the given values. The first step should always be to reset the transmitter, then if the error persists, try steps in Table 5.3. Start with the first corrective action, and then try the second.

Value	Description	Corrective Action
0x00000002	Sensor Transducer Error (Check	1. Restart processor
	TB_DETAILED_STATUS)	2. Send to service center
0x00000004	Manufacturing Block Integrity Error	1. Restart processor
		2. Send to service center
0x00000008	HW/SW Incompatible	1. Restart processor
		2. Send to service center
0x00000010	NV Integrity Error	1. Restart processor
		2. Send to service center
0x00000040	ROM Integrity Error	1. Restart processor
		2. Send to service center

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.

•Out of Service (OOS) The block is not processing its tasks. When the resource block is in OOS, all blocks within the resource (device) are forced into OOS. The BLOCK_ERR parameter shows Out of Service. In this mode, you can make changes to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes.

Alarm Detection

A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the resource block are defined above.

A write alarm is generated whenever the WRITE_LOCK parameter is cleared. The priority of the write alarm is set in the WRITE_PRI parameter:

Alarms are grouped into five levels of priority

Priority
Number	Priority Description

0Alarm is disabled.

1Alarm is detected, but not sent as a report.

2Alarm report is sent, but does not require operator attention.

3-7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.

8-15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.

Status Handling

There are no status parameters associated with the resource block.
