4 Function block actual mode does not
change with target mode.
4a Resource block actual mode is Out of Service. 4a Change Resource block target mode to Auto (see
page 45, Resource Block Mode, or host system
documentation).
4b Transducer block actual mode is not Auto. 4b Change transducer block target mode to Auto (see
page 62, Transducer Block Mode or host system
documentation).
4c Schedules that define when function blocks execute
are not set correctly.
4c Set the schedules using host system or
configuration tool. All function blocks must be in a
schedule that is downloaded to the device.
4d Configuration error 4d Look for configuration error bit in BLOCK_ERR. By
default, all enumerature type parameters are initialized
to 0 (undefined). They must be configured before the
block can be put into service.
5 Input or Output Block does not go to
mode target
5a Resource block actual mode is Out of Service 5a Change Resource block target mode to Auto (see
page 45, Resource Block Mode, or host system
documentation).
5b Transducer block actual mode is not Auto. 5b Change transducer block target mode to Auto (see
page 62, Transducer Block Mode or host system
documentation).
5c Transducer has detected a hardware failure. 5c A bad status is passed to the block's READBACK or
FIELD_VAL parameter. See transducer section of
Detailed Setup for repair information.
5d Wrong output block is active. 5d Use Outblock Selection to select the desired output
block. The deselected block will have a bad status for
READBACK. This will keep it in IMAN mode when target
is other than OOS.
5e Output block is not licensed. 5e The Actual Block Mode (MODE_BLK.ACTUAL [5.2])
will remain out of service and the block cannot be
scheduled if the block has not bee licensed. Contact
your Emerson Process Management sales office to
upgrade product licensing.
5f Schedules that define when function blocks execute
are not set correctly.
5f Set the schedules using host system or configuration
tool. All function blocks must be in a schedule that is
downloaded to the device.
5g Configuration error. 5g Look for configuration error bit in BLOCK_ERR. By
default, all enumerature type parameters are initialized
to 0 (undefined). They must be configured before the
block can be put into service.
6 Block dynamic parameters do not
update
6a Block actual mode is Out of Service 6a Change the block target mode to an operational
mode (see Appendix D, F
OUNDATION fieldbus
Communication and host system documentation).
7 Transducer block Setpoint
(FINAL_VALUE [13]) is not being
automatically updated from the AO
block.
7a Transducer block mode in not Auto. 7a Change transducer block mode to Auto.
7b AO block is not active. 7b Change Outblock Selection to AO Control.
8 Transducer block setpoint
Setpoint(D) (SETPOINT_D [32]) is not
being automatically updated from the
DO block.
8a Transducer block mode is not Auto. 8a Change transducer block mode to Auto.
8b DO block is not active. 8.b Change Outblock Selection to DO Control.
9 Valve does not move when the set
point is changed
9a A function block actual mode is Out of Service or
Transducer Block Actual mode is Out of Service or
Manual.
9a1 Change the target mode to an operational mode
(see Appendix D, F
OUNDATION fieldbus Communication
and host system documentation).
9a2 Verify that the correct block (AO or DO) is
configured in Feature Select in the resource block. Only
the selected out block is able to set the transducer
setpoint and move the valve.
9b Pneumatic connections are incorrect or supply
pressure is incorrect
9b Check pneumatic connections and supply pressure.
Be sure supply pressure regulator is set correctly (see
Pneumatic Connections on page 26).
