  • Communication protocol: ABB SPA-Bus.
  • The station address is a number in the range of 1 to 999, 0 is not used, 900 is reserved for broadcast.
  • Time parameter settings - Polling parameters, are ignored, the polling of the values is executed in the shortest possible period.
  • Time parameter - Synchronization time, is ignored, a real-time synchronization via the broadcast messages is controlled by the protocol line parameters "Time T Broadcast Period" and "Date and Time D Broadcast Period".

Recovery Delay
Communication with the station is delayed by defined time in case of a communication error. If a line contains more stations (protective devices) and one of them fails, it can slow down the communication to other functioning stations. Next recovery of the communication with a failed station will be delayed by a defined value (time). If the line contains only a single station, the parameter value should be 0 seconds.sec10 sec

Poll Events
This parameter activates a periodic event reading by the function "Last events L". Time synchronization of the protective device must be also enabled. See the communication line parameters "Time T Broadcast Periode" and "Date and Time D Broadcast Periode".YES/NOYES

  • Channel: channel number is a required numerical address parameter intended for all data categories except for F and C.
  • Category: data category code; if it is unknown, select "Not defined", if it is known, you can choose one of the following data categories:
    • Input data I
    • Output data O
    • Setting Values S
    • Variable V
    • Memory data M
    • Slave identification F
    • Slave status C

    "Slave Identification F" and "Slave Status C" categories don't require specifying of any other address parameter. The value is unique within the device.

    • "Slave identification F" returns 10 characters which identify a device. We recommend to configure it as I/O tag of TxtI type.

    • "Slave status C" returns a number 0, 1, 2 or 3. See also Note 1.

  • Data Number: a mandatory numerical address parameter for all data categories except for F and C.
  • Poll: enables periodic polling for all data categories except for "Not defined". The data category "Slave identification F" does not require periodic polling because it is static data. If the periodic polling is disabled, the object is polled only when the communication is started or when I/O tag value is unknown.
  • Event code - Intermediate position (00): a numerical address of event when the object goes to "Intermediate position". A value of "TRANS" can be set for Qi I/O tag type or a numerical value according to the protocol parameter "Value for intermediate position" for I/O tags of Ai, Ao, Ci, Co types. A configuration is not allowed for I/O tags of Di, Dout types.
  • Event code - Off/Open position: a numerical address of event when the object goes to "Off/Open position". A value of "OFF" can be set for Qi I/ tag type or a numerical value according to the protocol parameter "Value for Off/Open position" for Ai, Ao, Ci, Co I/O tags.
  • Event code - On/Close position: a numerical address of event when the object goes to "On/Close position". A value of"ON" can be set   for Qi I/O tag type or a numerical value according to the protocol parameter "Value for On/Close position" for Ai, Ao, Ci, Co I/O tags.
  • Event code - Invalid position (11): a numerical address of event when the object goes to "Invalid position". A value of"ERROR" can be set  for Qi I/O tag type or a numerical value according to the protocol parameter "Value for invalid position" for Ai, Ao, Ci, Co I/O tags. The configuration is not allowed for Di, Dout I/O tags.
