Table 7‐2. Instrument Troubleshooting (Continued)
Symptom
4 Function block actual mode does not
change with target mode.
5 Input or Output Block does not go to
mode target
6 Block dynamic parameters do not
update
7 Transducer block Setpoint
(FINAL_VALUE [13]) is not being
automatically updated from the AO
block.
8 Transducer block setpoint
Setpoint(D) (SETPOINT_D [32]) is not
being automatically updated from the
DO block.
9 Valve does not move when the set
point is changed
Possible Cause
4a Resource block actual mode is Out of Service.
4b Transducer block actual mode is not Auto.
4c Schedules that define when function blocks execute
are not set correctly.
4d Configuration error
5a Resource block actual mode is Out of Service
5b Transducer block actual mode is not Auto.
5c Transducer has detected a hardware failure.
5d Wrong output block is active.
5e Output block is not licensed.
5f Schedules that define when function blocks execute
are not set correctly.
5g Configuration error.
6a Block actual mode is Out of Service
7a Transducer block mode in not Auto.
7b AO block is not active.
8a Transducer block mode is not Auto.
8b DO block is not active.
9a A function block actual mode is Out of Service or
Transducer Block Actual mode is Out of Service or
Manual.
9b Pneumatic connections are incorrect or supply
pressure is incorrect
4a Change Resource block target mode to Auto (see
page 45, Resource Block Mode, or host system
documentation).
4b Change transducer block target mode to Auto (see
page 62, Transducer Block Mode or host system
documentation).
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 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.
5a Change Resource block target mode to Auto (see
page 45, Resource Block Mode, or host system
documentation).
5b Change transducer block target mode to Auto (see
page 62, Transducer Block Mode or host system
documentation).
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 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 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 Set the schedules using host system or configuration
tool. All function blocks must be in a schedule that is
downloaded to the device.
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.
6a Change the block target mode to an operational
mode (see Appendix D, F
Communication and host system documentation).
7a Change transducer block mode to Auto.
7b Change Outblock Selection to AO Control.
8a Change transducer block mode to Auto.
8.b Change Outblock Selection to DO Control.
9a1 Change the target mode to an operational mode
(see Appendix D, F
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 Check pneumatic connections and supply pressure.
Be sure supply pressure regulator is set correctly (see
Pneumatic Connections on page 26).
