Description of the block parameters of the function block 9.2.3.5.
parameter Description
rEaDBaCk_D This parameter returns the position of the valve and the sensors.
Bit 7 6 5 4 3 2 1 0
0 0 Do not initialize
0 1 Closed
1 0 Open
1 1 On the move
Status sensor 1
Short-circuit sensor
No-load sensor 1
Status sensor 2
Short-circuit sensor
No-load sensor 2
1 = active
0 = inactive
sp_D Set-point value
Bit 0 in the value specifies the valve position. The transferred status must be a
“good” status, e.g. 0x80.
out_D Process value of the valve position. Bit 0 in the value indicates the valve position.
rCas_in_D Set-point value in the RCAS status (Remote Cascade). Bit 0 in the value specifies
the valve position. The transferred status must be a “good” status, e.g. 0x80.
rCas_out_D Process value of the valve position in the RCAS status. Bit 0 in the value indicates
the valve position.
ChannEl Indicates the transducer block. There are channels 1-4. The function blocks are per-
manently assigned.
inVErt Inverts the set-point value in the AUTO or RCAS status0 = do not invert1 = invert
fsaVE_timE Time in seconds after which the “Failsave” action starts following a break in the
cyclic communication. The maximum value for this time is approx. 18 hours.
fsaVE_typ Response to “Fail save”
0 = Valve retains the last status
1 = Valve switches according to FSAVE_VAL_D
2 = Isolate valve
fsaVE-Val-D Valve position in “Fail save”, if selected.
simulatE Allows the simulation of READBACK_D
