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.
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
Status Handling
There are no status parameters associated with the resource block.
