Parameter lists
DO FB:
MODE_BLK (5)
Storage class N; read/write capability r/w; supported modes ALL
Operating mode of DO Function Block
– Target Mode
– Actual Mode (read only)
– Permitted Mode
– Normal Mode (read only)
•
AUTO · The discrete set point entered by the operator is used over the SP_D parameter
upon execution of the DO Function Block.
•
MAN · The discrete output value of the DO Function Block can be entered manually by
the operator over the OUT_D parameter.
•
CAS · The DO Function Block receives the discrete set point directly from an upstream
function block over the CAS_IN_D parameter for internal processing of the out value.
The DO Function Block is implemented.
•
RCAS · The DO Function Block receives the discrete set point directly from the fieldbus
host system over the RCAS_IN_D parameter for internal processing of the out value. The
DO Function Block is implemented.
•
O/S · The DO Function Block is not executed. The last value or the determined value
during an active fault processing is issued at the OUT_D parameter.
DO FB:
OUT_D (9)
Storage class S; read/write capability r/w; supported modes O/M
Out value of the DO Function Block (value, limit and status)
•
Range of OUT_SCALE ±10 %; unit of the XD_SCALE parameter group
Note:
The OUT value can be entered manually when the MAN mode is selected in the
MODE_BLK parameter.
DO FB:
PV_D (7)
Storage class D; read capability r
Discrete process variable used to execute the module (value and status)
DO FB:
PV_STATE (11)
Storage class S; read/write capability r/w; supported modes ALL
Status of PV_D and SP_D parameters
DO FB:
RCAS_IN_D (22)
Storage class N; read/write capability r/w; supported modes ALL
Discrete set point for internal calculation of the out value (value and status)
RCAS_IN_D value is provided by the fieldbus host system.
Note:
This parameter is only active in RCAS mode.
