Other Boolean signals, for example a start or a trip signal from a protectionfunction is event masked in the EVENT function block.Double indications M15083-126 v3Double indications can only be reported for the first 8 inputs on an EVENTfunction block.• 00 generates an intermediate event with the read status 0• 01 generates an open event with the read status 1• 10 generates a close event with the read status 2• 11 generates an undefined event with the read status 3Analog value M15083-135 v4All analog values are reported cyclic. The reporting interval is taken from theconnected function if there is a limit supervised signal. Otherwise it is taken fromthe EVENT function block.Command handling M15083-80 v4Commands are transferred using transparent SPA-bus messages. The transparentSPA-bus message is an explicit LON message which contains an ASCII charactermessage following the coding rules of the SPA-bus protocol. The message is sentusing explicit messages with message code 41H and using acknowledged transportservice.Both the SPA-bus command messages (R or W) and the reply messages (D, A orN) are sent using the same message code.
