Supported Modes
Out of Service (OOS) and AUTO are supported modes for the linking device.
BLOCK_ERR
The BLOCK_ERR of the resource block indicates the following causes for the
error:
•
Device Fault State Set – When FAULT_STATE is active.
•
Out of Service – When the block is in OOS mode.
Block Configuration Out of Service - Incorrect parameter value or uninitialized
value for a parameter that requires a value or selection for the block to operate.
Parameters
Table 5
describes the resource block parameters.
