TCMYLTC or TCLYLTC (84) function block for the same transformer as TR8ATCC
(90) block belongs to.
There are 10 binary signals and 6 analog signals in the data set that is transmitted from
one TR8ATCC (90) block to the other TR8ATCC (90) blocks in the same parallel
group:
Table 37:
Binary signals
Signal
Explanation
TimerOn
This signal is activated by the transformer that has started its timer and is going to
tap when the set time has expired.
automaticCTRL
Activated when the transformer is set in automatic control
mutualBlock
Activated when the automatic control is blocked
disc
Activated when the transformer is disconnected from the busbar
receiveStat
Signal used for the horizontal communication
TermIsForcedMaster
Activated when the transformer is selected Master in the master-follower parallel
control mode
TermIsMaster
Activated for the transformer that is master in the master-follower parallel control
mode
termReadyForMSF
Activated when the transformer is ready for master-follower parallel control mode
raiseVoltageOut
Order from the master to the followers to tap up
lowerVoltageOut
Order from the master to the followers to tap down

Manual configuration of VCTR GOOSE data set is required. Note that
both data value attributes and quality attributes have to be mapped. The
following data objects must be configured:
