Table 10-2. Instrument Troubleshooting (Continued)
Possible Cause
2.a Incorrect signal level.
2.b Excess noise on segment.
2.c Electronics failing.
3.a Resource block parameter Write Lock may be set
to Locked.
3.b If a transducer block parameter, the mode may be
incorrect or the parameter may be protected.
3.c You have attempted to write a value that is outside
the valid range.
3.d Function block or in/out block mode may be
incorrect.
4.a Resource block actual mode is Out of Service.
4.b Transducer block actual mode is Out of Service
4.c Schedules that define when function blocks
execute are not set correctly.
4.d Configuration error
5.a Resource block actual mode is Out of Service
5.b Transducer block actual mode is Out of Service.
5.c Transducer has detected a hardware failure.
5.d Out block not configure in RB.FEATURE_SEL.
5.e Schedules that define when function blocks
execute are not set correctly.
5.f Configuration error.
6.a Block actual mode is Out of Service

Action
2.a1 Check that segment is properly terminated (see
host system documentation).
2.a2 Wrong cable type or segment length too long.
See Site Planning Guide.
2.a3 Bad power supply or conditioner.
2.b1 Check integrity of wiring connections. Make sure
cable shield is grounded only at the control system.
2.b2 Check for corrosion or moisture on terminals in
terminal box (refer to page 10-8 for terminal box
information).
2.b3 Check for bad power supply.
2.c. Replace printed wiring board assembly (see
Replacing the PWB Assembly on page 10-7).
3.a Change Write Lock to Not Locked (refer to page
5-4 of Detailed Setup / Blocks).
3.b1 Check table 5-85. If necessary change the
transducer block target mode to Manual.
3.b2 Check table 5-85. If necessary change data
protection.
3.c Check the range values listed for the parameter
(refer to Detailed Setup / Blocks, Section 5).
3.d. Confirm that block is in correct mode for writing
to any given parameter.
4.a Change Resource block target mode to Auto (see
page 5-4, Resource Block Mode, or host system
documentation).
4.b Change transducer block target mode to Auto
(see page 5-23, Transducer Block Mode or host
system documentation).
4.c Set the schedules using host system or
configuration tool. All function blocks must be in a
schedule that is downloaded to the device.
4.d 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.a Change Resource block target mode to Auto (see
page 5-4, Resource Block Mode, or host system
documentation).
5.b Change transducer block target mode to Auto
(see page 5-23, Transducer Block Mode or host
system documentation).
5.c A bad status is passed to the block's READBACK
or FIELD_VAL parameter. See transducer section of
Detailed Setup for repair information.
5.d DO Control Bit must be set in RB.FEATURE_SEL
to use DO block instead of AO block. The deselected
block will have a bad status for READBACK. This will
keep it in IMAN mode when target is other than OOS.
5.e Set the schedules using host system or
configuration tool. All function blocks must be in a
schedule that is downloaded to the device.
5.f 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.a Change the block target mode to an operational
mode (see F fieldbus Communication,
OUNDATION
Appendix A and host system documentation).
