Device Diagnostics

Resource Block Error
(RB > Device Diagnostics > Resource Block Error)
RB > Device Diagnostics > Resource Block Error
Field Communicator
Block Error (BLOCK_ERR [6]) indicates an error status associated with hardware or software for the resource block.
Table 6‐1 lists conditions reported in the BLOCK_ERR [6] parameter. Conditions in italics are not applicable for the
resource block and are provided only for your reference.
Device State
RB > Device Diagnostics > Device State
Field Communicator
Device State (RS_STATE [7]) indicates the state of the function blocks. Four states are possible:
d
Initialization—The instrument enters this state upon restart or failure. The function blocks are in the IMan mode.
During the initialization state, all unreported function block alarms are automatically confirmed and acknowledged.
Once the instrument is considered operational, block execution is scheduled and the instrument state moves to
Online.
d
Online—The instrument will be in this state if it is operational. The function blocks are initially in the Auto mode, but
can be changed to a higher level mode.
d
Standby—The instrument enters this state if the resource block mode is Out of Service (OOS). In this state all
function block modes are forced to Out of Service. The transducer block mode is not affected. When the resource
block mode is changed to Auto, the instrument state moves to Online.
d
Failure— The instrument moves to this state whenever a hardware or memory failure is detected which would
prevent reliable operation. All function blocks and the transducer block modes are Out of Service.
Write Lock

Field Communicator
D Write Alarm: Alarm State
D Write Lock
Write Lock (WRITE_LOCK [34]) determines if writes are permissible to other device parameters. The Soft Write Lock
feature must be selected to be able to use Write Lock (see Selecting Features). When Write Lock is set to Locked, no
writes are permitted to any parameters within the device except to set Write Lock to Not Locked. When locked, the
block functions normally, updating inputs and outputs and executing algorithms. When Write Lock is set to Not
Locked, the Write Alarm alert is active.
