Discrete Input Function Block Specific Parameters (Slots 2 through 5)
Parameter Description
OUT_D
(Index 26) This parameter is the process variable of the discrete input block in Auto and
RCas mode and is the value specified by the operator/engineer in Man and LO.
CHANNEL
(Index 30) Reference to the active transducer block which provides the measurement value
to the function block.
INVERT
(Index 31) Indicates whether the SP_D should be logically inverted before writing to OUT_D
in mode Auto or RCas.
0 = not inverted
1 = invert
FSAFE_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.
FSAFE_VAL_D
(Index 37) The preset discrete OUT_D used if FSAFE_TYPE = 0 and FSAFE is activated.
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
Discrete Output Function Block Specific Parameters (Slots 6 and 7)
Parameter Description
SP_D
(Index 25) Setpoint of function block used in mode Auto.
OUT_D
(Index 26) This parameter is the process variable of the discrete output block in Auto and
RCas mode and is the value specified by the operator/engineer in Man and LO.
READBACK_D
(Index 28) In the case of valve control, this object indicates the position of discrete valve and
the sensor states.
RCAS_IN_D
(Index 30) Target setpoint and status provided by a supervisory host to the discrete output
block used in mode RCas.
CHANNEL
(Index 33) Reference to the active transducer block which provides the measurement value
to the function block.
