Section 4 Detailed Setup

Resource Block

The resource block contains the hardware specific characteristics associated with a device; it has no input or output
parameters. The resource block monitors and controls the general operation of other blocks within the device. Most of
the resource block parameters are operational parameters that provide information about the instrument such as
identification, hardware information, available options, etc. and are read only. Configuration of the resource block
involves selecting features from those that are available, setting the mode, setting write lock, and setting up alert
reporting details.
The following procedures address only the key resource block parameters; however, all resource block parameters are
listed in table 4‐3.

Resource Block Mode

Modes
The resource block can be in one of two modes (MODE_BLK [5]):
d
Automatic (Auto) is the operational mode for this block. When the resource block is in the Auto mode, all other
function blocks are allowed to function normally.
d
Out of Service (OOS)—Placing the resource block in Out of Service mode stops all function block execution, by
setting their modes to Out of Service as well. The actual mode of the function blocks is changed to Out of Service, but
the function block target modes are retained. Placing the resource block in the Out of Service mode does not affect
the mode of the transducer block.

Write Lock

Write Lock (WRITE_LOCK [34]) determines if writes are permissible to other device parameters. The write lock feature
must be selected to be able to use Write Lock (see Features Available). 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 device
functions normally, updating inputs and outputs and executing algorithms. When Write Lock is set to Not Locked, the
Write Alarm (WRITE_ALM [40]) alert is active.
Write Priority (WRITE_PRI [39]) sets the priority for Write Alarm. The lowest priority is 0. The highest is 15.
