• The permitted modes are listed for each block.
• The block must be in an automatic mode for normal
operation.
NOTE: The MODE_BLK target parameter must be OOS (out of service)
to change configuration and calibration parameters in that func-
t
ion block (when in OOS, the normal algorithm is no longer exe-
cuted and any outstanding alarms are cleared).
All blocks must be in an operating mode for the device to oper-
ate. This requires the Resource Block to be in “AUTO” and the
Transducer Block to be in “AUTO” before the Function Blocks
can be placed in a mode other than OOS (out of service).
BLOCK_ERR: a parameter that reflects the error status of
hardware or software components associated with, and
directly affecting, the correct operation of a block.
NOTE: A BLOCK_ERR of “Simulation” in the Resource Block does not
mean simulation is active—it merely indicates that the simula-
tion enabling hardware jumper is installed.
4.2 Resource Block
The RESOURCE block contains data specific to the
E3 MODULEVEL transmitter, along with some
information about the firmware.
NOTE: The Resource Block has no control function.
MODE_BLK: Must be in AUTO in order for the remain-
ing blocks in the transmitter to operate.
NOTE: A Resource Block in “out of service” will stop all function block
execution in the transmitter.
RS_STATE (Resource State): identifies the state of the
RESOURCE block state machine. Under normal operating
conditions, it should be “On-Line.”
DD_RESOURCE: a string identifying the tag of the
resource that contains the Device Description for this device.
MANUFAC_ID: contains the MAGNETROL International,
Incorporated F
OUNDATION fieldbus
™
manufacturer’s ID
number, which is 0x000156.
DEV_TYPE: the model number of the E3 MODULEVEL
transmitter (0x0003). It is used by interface devices to
locate the Device Descriptor (DD) file for this product.
DEV_REV: contains the firmware revision of the
E3 MODULEVEL transmitter. It is used by interface
devices to correctly select the associated DD.
