Parameter Description

INVERT

(Index 34)

Indicates whether the SP_D should be logically inverted before writing to OUT_D

in mode Auto or RCas.

0 = not inverted

1 = invert

FSAVE_TIME

(Index 35)

Time in seconds from detection of failure of the actual used setpoint (SP_D = bad

or RCAS_IN <> Good) to the action of the block if the condition still exists.

FSAVE_TYPE

(Index 36)

Deﬁnes reaction of the device if failure of actual used setpoint is still detected after

FSAFE_TIME or if the status of actual used setpoint is Initiate Fail-Safe.

FSAVE_VAL_D

(Index 37)

The preset discrete OUT_D used if FSAFE_TYPE = 0 and FSAFE is activated.

RCAS_OUT_D

(Index 38)

Function block setpoint and status provided to a supervisory host for monitoring/back

calculation and to allow action to be taken under limited conditions or mode change.

SIMULATE

(Index 40)

For commissioning and maintenance reasons, it is possible to simulate the input

or output values by modifying the value and the status. That means that the

transducer block and the function block will be disconnected.

CHECKBACK_D

(Index 49)

Detailed information of the device, bitwise coded. More than one message

possible at once.

CHECK_BACK_MASK

(Index 50)

Deﬁnition of supported CHECK_BACK information bits.

0 = not supported

1 = supported

Analog Input Function Block Speciﬁc Parameters (Slot 8)

Parameter Description

OUT

(Index 26)

This parameter is the process variable of the analog output block in engineering

units in Auto and RCas mode and is the valued speciﬁed by the operator/engi-

neering in Man and LO mode.
