SPAJ 140 C Series ABB

Serial communication parameters

When the combined overcurrent and earth fault relay module SPCJ 4D29  is connected to a data communication unit. e.g. SRIO 1000M, over a fibre-optic SPA bus, the module will spontaneously generate event markings e.g. for a printer. The events are printed out in the format: time, text and event code. The text can be defined and written by the user into the communication unit.

The events coded E1...E16  can be included in or excluded from the event reporting by writing an event mask V155 for the overcurrent events and V156  for earth-fault events to the module over the SPA bus. The event masks are binary numbers coded to decimal numbers. The event codes E1...E8 are represented by the numbers 1, 2, 4...128. An event mask is formed by multiply ing the above numbers either by 0, event not included in reporting, or 1, event included in reporting and by adding the numbers received. Check for the procedure of a manual calculation of the checksum.

The event masks V155 and V156 may have a value within the range 0...255. The default value of the combined overcurrent and earth fault relay module SPCJ 4D29 is 85 both for overcurrent and earth-fault events, which means that all start and operate events are included in the reporting, but not the resetting. Check for the procedure of a manual calculation of the checksum.

The output signals are monitored by codes E17...E26 and these events can be included in or excluded from the event reporting by writing an event mask V157 to the module. The event mask is a binary number coded to a decimal number. The event codes E17...E26 are repre sented by the numbers 1, 2, 4...512. An event mask is formed by multiplying the above num bers either by 0, event not included in reporting or 1, event included in reporting and by adding the numbers received. Check for the procedure of a manual calculation of the checksum.

The event mask V157  may have a value within the range 0...1024. The default value of the combined overcurrent and earth-fault relay module SPCJ 4D29 is 768  which means that only the operations are included in the report ing.

Codes E50...E54 and the events represented by these cannot be excluded from the reporting.

More information about the serial communica tion over the SPA bus can be found in the manual "SPA bus communication protocol", code No 34 SPACOM 2 EN1.
