2600T SERIES | PRESSURE TRANSMITTERS | OI/266/FF-EN REV. E
59
The differential pressure generated by the flow primary is for the maximum flow rate 2500 mmH2O, for the max reverse flow rate
2500 mmH2O.
The transmitter will have to be configured as follows:
Calibrated span: LRV = -2500mmH2O
URV = 2500mmH2O
Linearization Type = Bidirectional flow
Once configured as above the transmitter will deliver:
flowrate 100 lt/hr reverse: output= 0%
no flowrate: output= 50%
Flow rate 100 lt/h: output= 100%
Cylindric lying tank
This function is used to measure the volumetric level into a cylindrical horizontal tank with flat ends. The transmitter calculates the
volume from the measured filling level.
Spherical Tank
This function is used to measure the volumetric level into a spherical tank. The transmitter calculates the volume from the
measured filling level.
Block Mapping
Idx Parameter Description / Range / Selections / Notes
 BLOCK_OBJ
In the Block Object data structure, there are different items describing the block characteristics. Execution period,
Number of parameters in the block, the DD Revision, Profile Revision, View Objects characteristics and so on
 ST_REV
The revision level of the Static data associated with the Function Block. The revision level is incremented each time a
static parameter value (S – under Storage) in the block is changed.
 TAG_ DESC The user description of the intended application of the block
 STRATEGY The strategy field can be used to identify grouping of blocks. This data is not checked or processed by the block.
 ALERT_KEY The identification number of the plant unit. This information may be used in the host for sorting alarms, etc.
 MODE_BLK
TARGET AUTO / OOS The selectable modes by the operator.
ACTUAL The mode the block is currently in.
PERMITTED AUTO / OOS Allowed modes that the target may take on
NORMAL AUTO The common mode for the Actual.
 BLOCK_ERR
This parameter reflects the error status associated with the hardware or software components associated with a
block. It is a bit string, so that multiple errors may be shown.

 UPDATE_EVT This alert is generated by any change to the static data
 BLOCK_ALM
The block alarm is used for all configuration, hardware, and connection failure or system problems in the block.
The cause of the alert is entered in the sub-code field. The first alert to become active will set the Active Status in the
status parameter. As soon as the Unreported status is cleared by the alert reporting task, another block alert may be
reported without clearing the Active Status, if the sub-code has changed
