Section 3
LON operation principle
coding rules of the SPA-bus protocol. The message is sent using explicit messages with
message code 41H and using acknowledged transport service.
Both the SPA-bus command messages (R or W) and the reply messages (D, A or N) are sent
using the same message code. It is mandatory that one device sends out only one SPA-bus
message at a time to one node and waits for the reply before sending the next message.
For commands from the operator workplace to the IED for apparatus control, that is the
function blocks type SCSWI 1 to 30, SXCBR 1 to 18 and SXSWI 1 to 24, the SPA addresses are
according to table 3.
