Instruction Manual D103434X012 Blocks November 2014 When the block is in Cas mode and the CAS_IN [17] input goes bad, the block sheds mode to the next lower permitted mode. You can configure the shed option as follows: Shed With Return Options Remote cascade connection failure shifts actual mode but keeps trying to restore remote cascade (in other words, the remote cascade target mode stays in effect).
Blocks Instruction Manual November 2014 D103434X012 D Shed logic never results in a non‐permitted target mode. D Shed logic never attempts to attain an actual mode of Auto or Cas if that mode is not permitted. Status Handling Output or readback fault detection is reflected in the status of PV [7], OUT [9], and BKCAL_OUT [25]. A limited SP [8] condition is reflected in the BKCAL_OUT [25] status.
Instruction Manual Blocks November 2014 D103434X012 input connector. In RemoteCascade (RCas) mode, the SP [8] comes from a host computer that writes to RCAS_IN [28]. The range and units of the SP [8] are defined by the PV_SCALE [11] attribute. In Manual (Man) mode the SP [8] automatically tracks the PV [7] value when you select the SP‐PV Track in Man I/O option in IO_OPTS [14]. You can disable this option in OOS mode only.
Instruction Manual Blocks November 2014 D103434X012 FSTATE_TIME [23]: The length of time, in seconds, that the AO block will wait to set Fault State. When Fault State is set, the OUT [9] value goes to either the FSTATE_VAL [24] value or holds its last position, depending on I/O_OPTS [14]. When the block has a target mode of CAS, a fault condition will be detected if the CAS_IN [17] has a BAD status or an Initiate Fault State substatus is received from the upstream block.
Instruction Manual Blocks November 2014 D103434X012 Application Information The configuration of an AO function block and its associated output channels depends on the specific application. A typical configuration for the Analog Output involves the following attributes: PV_SCALE Set the range and engineering units to values that correspond to the operation range. For the digital level controller, PV_SCALE [11] is typically set between 0 and 100%.

Instruction Manual Blocks November 2014 D103434X012 Arithmetic (ARTH) Function Block The Arithmetic function block (figure B‐17) provides the ability to configure a range extension function for a primary input and applies the nine (9) different arithmetic types as compensation to or augmentation of the range extended input. All operations are selected by parameter and input connection. Figure B‐17.
Blocks Instruction Manual November 2014 D103434X012 Block Execution The Arithmetic function block provides range extension and compensation through nine (9) arithmetic types. There are two inputs (IN and IN_LO) used in calculating PV. PV is then combined with up to three inputs (IN_1, IN_2, and IN_3) through the user selected compensation function (ARITH_TYPE) to calculate the value of func. A gain is applied to func and then a bias is added to get the value PRE_OUT. In AUTO, PRE_OUT is used for OUT.
Instruction Manual D103434X012 Blocks November 2014 Figure B‐18. Arithmetic Function Block Schematic Different fluids over the same temperature range have different effects on level due to their thermal expansion coefficients. Vessel geometry also plays a major role. As the height of the vessel increases, the effect of thermal expansion becomes more apparent. Figure B‐19 shows the relative temperature effects on a level signal. Figure B‐19.
Blocks Instruction Manual November 2014 D103434X012 Compensation - Linear. This allows a ratio to be set up that increases the level indication at block output for an increase in the tank temperature relative to ambient temperature. This application can be applied to very large storage tanks whose contents are subject to thermal expansion and contraction during seasonal changes in temperature. Figure B‐20.
Instruction Manual D103434X012 Blocks November 2014 Compensation inputs which are not configured are not used in the calculation. PV is always used. If there is a divide by zero and the numerator is positive, func will be limited to COMP_HI; if the numerator is negative, func will be limited to COMP_LO.

Instruction Manual FOUNDATION fieldbus Communication D103434X012 November 2014 Appendix C FOUNDATION fieldbus CommunicationC‐ FOUNDATION Fieldbus Communication DLC3020f digital level controllers use the FOUNDATION fieldbus to communicate with other fieldbus instruments and the control system. Fieldbus is an all digital, serial, two‐way communication system which interconnects “field” equipment such as transmitters, digital level controllers, and process controllers.
Instruction Manual FOUNDATION fieldbus Communication November 2014 D103434X012 input and output parameters. However, they may be accessed and modified remotely, as specified by the function block. Figure C‐1 illustrates the internal structure of a function block. When execution begins, input parameter values from other blocks are snapped‐in by the block. The input snap process ensures that these values do not change during the block execution.
Instruction Manual FOUNDATION fieldbus Communication November 2014 D103434X012 data from sensors and ensure proper writes to the actuator without burdening the function blocks that use the data. The transducer block also isolates the function block from the specific characteristics of the physical I/O. Block Modes All blocks have modes. The mode determines the source of the set point, the destination of the output, how the block executes, and the relationship between setpoint and output.

CHANGING THE RESOURCE BLOCK TO OUT OF SERVICE CHANGES ALL FUNCTION BLOCKS TO OUT OF SERVICE, BUT DOES NOT AFFECT THE TRANSDUCER BLOCK. 2. CHANGING A DOWNSTREAM BLOCK TO OUT OF SERVICE AFFECTS THE UP STREAM BLOCK.
Instruction Manual FOUNDATION fieldbus Communication November 2014 D103434X012 Remote Cascade (RCas)—The block performs the specified calculations based on a set point from a host computer or others via the remote cascade input and outputs the result. If the block has any outputs, these continue to update. Examples of Modes for Various Operational Statuses Table C‐2 shows examples of block mode combinations in a digital level controller (however it does not show all combinations).

Instruction Manual FOUNDATION fieldbus Communication November 2014 D103434X012 Limit Propagation The following describes limit propagation: AO Block D If the valve position is below the low cutoff value, the AO block READBACK status limit is LOW_LIMITED. D If the valve position is above the high cutoff value, the AO block READBACK status limit is HIGH_LIMITED. D If the transducer block actual mode is Auto and the above conditions are not true, the AO block READBACK status limit is NOT_LIMITED.
FOUNDATION fieldbus Communication November 2014 Instruction Manual D103434X012 D recognizes and adds new devices to the link. D removes non‐responsive devices from the link. D distributes Data Link (DL) and Link Scheduling (LS) time on the link. Data Link Time is a network‐wide time periodically distributed by the LAS to synchronize all device clocks on the bus. Link Scheduling time is a link‐specific time represented as an offset from Data Link Time.
