6.1.10 SPA
The device can act as a SPA slave. SPA can be selected as the communication protocol for the COM
B port (RS-485 port in the CPU module). When the device includes a serial RS-232 card connector,
the SPA protocol can also be selected as the communication protocol for the COM E and COM F
ports. Please refer to the chapter "Construction and installation" in the device manual to see the
connections for these modules.
The data transfer rate of SPA is 9600 bps, but it can also be set to 19 200 bps or 38 400 bps. As a
slave the device sends data on demand or by sequenced polling. The available data can be
measurements, circuit breaker states, function starts, function trips, etc. The full SPA signal map can
be found in AQtivate (

To access SPA map and event list, an .aqs configuration file should be downloaded from the
relay.
6.2 Analog fault registers
At
Communication
→
General I/O
→
Analog fault registers the user can set up to twelve (12) channels
to record the measured value when a protection function starts or trips. These values can be read in
two ways: locally from this same menu, or through a communication protocol if one is in use.
The following table presents the setting parameters available for the 12 channels.
