Emerson IP258 Password not Open, Invalid Action not the Same Instrument, 10.3Communication Errors

Page 55

“PASSWORD NOT OPEN”

-If the Password in the MSM400 control unit memory is set “CLOSED”, then it will not be possible to load data from the SAFE or OFFLINE register. The Password protects the data in the MSM400.

“INVALID ACTION NOT THE SAME INSTRUMENT”

-If an attempt is made to transfer SAFE register data to the WORKING register of an MSM400 control unit which is not the origin of the SAFE register data, this will not be allowed. The message indicates that D731 on the currently connected loop is not the same as the D731 in the SAFE register.

“INSTRUMENT IN MULTIDROP MODE”

-The current output control circuitry in the MSM400 control unit is only active when the MSM400 is operating as a 0-20 or 4-20mA device. In a multidrop configuration the current is set to 4mA, and trimming and current set commands are inoperative.

D.10.3Communication Errors

Communications between the MSM400 control unit and the SMART interface/Psion organiser are subject to error checking and acknowledgement signals according to the HART protocol. This means that only valid messages are accepted, and if the message is invalid then it will be rejected.

The screen of the LCD will indicate if a message has not been received correctly. This is perhaps most likely to be seen when the Display parameters are being used, since these are updated with a new value in a message every 0.5 seconds. If the message is received incorrectly, the second and third lines of the display will show one of the following messages:

VERTICAL PARITY ERROR IN REPLY

OVERRUN ERROR IN REPLY

FRAMING ERROR IN REPLY

LONGITUDINAL PARITY ERROR IN REPLY

BUFFER OVERFLOW IN REPLY

Which describe the cause of the fault.

There is an identical group of errors in the outgoing message:

VERT PARITY ERROR IN OUTGOING MESSAGE

OVERRUN ERROR IN OUTGOING MESSAGE

FRAMING ERROR IN OUTGOING MESSAGE

LONGDNL PARITY ERROR IN OUTGOING MESSAGE

BUFFER OVERFLOW IN OUTGOING MESSAGE

If this occurs frequently, it is appropriate to check the electrical connections to the instrument loop, the presence of the SMART load resistor and that the SMART Communicator is attached at the correct position in the loop.

The “IN OUTGOING MESSAGE” group of error messages if displayed while accessing the Programme Parameters implies that the message from the SMART Communicator was not received correctly by the MSM400. Therefore the instructions in the message would have been rejected, and the Parameters remain unchanged at their previous value. This previous value will be shown on the LCD screen on the SMART Communicator after the error message, to prompt the operator to repeat the last parameter value amendment. During a Register transfer this message will automatically cause the Communicator to hold transmission, and suggest a retry because of the error.

The “IN REPLY” group of error messages if displayed when programming the instrument, signals a more significant communications failure. This indicates that the acknowledgement of the change instruction sent to the MSM400 was incorrect. It is not known whether the Parameter value in the MSM400 was changed or not. The SMART Communicator assumes that it was not changed, and reverts to the original
