Figure 153: Connection between TR8ATCC and TCMYLTC
The TR8ATCC function blocks have an output signal ATCCOUT, which is
connected to input YLTCIN on TCMYLTC. The data set sent from ATCCOUT to
YLTCIN contains 5 binary signals, one "word" containing 10 binary signals and 1
analog signal. For TR8ATCC data is also sent from output ATCCOUT to other
TR8ATCC function input HORIZx, when the master-follower or circulating current
mode is used.
