DP-V1 ErrorCode1

DP-V1

Read

DP-V1

Write

Possible Cause

Corrective Action

0xA0
(Read Error)

X

Read access to paramater, which could
not be retrieved (e.g. EEPROM error)

-

0xA1
(Write Error)

X

Write access filed (e.g. due to
EEPROM error)

-

0xB0
(Invalid Index)

X

X

Accessing a non-existing parameter.

Correct the Index in the service request and
retry.

0xB1
(Write Length Error)

X

Write access with incorrect amount of data
supplied.

Correct the number of bytes in the service
request and retry.

0xB5
(State Conflict)

X

Write access to a parameter currently being
locked with the parameter lock.

If applicable, unlock the parameter and retry.

0xB7
(Invalid Range)

X

The value in the service request was
outside the specified range.

Correct the value in the service request
and retry.

0xC0
(Read constrain conflict)

X

The length in the request doesn’t
match the actual size of the parameter.

The length in the request doesn’t
match the actual size of the parameter.

0xC1
(Write constrain conflict)

X

Write access to a read-only parameter.

0xC3
(Resource Busy)

X

Write acces to a parameter mapped as
Cyclic I/O

Table 4.6 Input and Output Troubleshooting Procedures

Failure Type

Failure Description

Corrective Action

Input 1, 2

Input 1 or 2 does not appear to
recognize a contact closure

1. Check the supply voltage
2. If the applicable contact closed but the E1 Plus PROFIBUS Module Input does not recognize the closure,

check the continuity and wiring to the connected contact.

3. Measure the voltage across and current through the applicable input. Verify they are within the ratings

of the E1 Plus PROFIBUS Module (See Appendix A).

4. Check the programmable controller ladder logic and I/O mapping.

Input 1, 2

Trip reset operation

Check the programming of Parameter 28, IN1 Assignment or Parameter 29, IN2 Assignment.
