Please therefore note the following:
Figure 6-49
If the "Target Ship" is the next target to be specified after the "Target Hopper" is reached and
the hoist target is changed first due to time delays, a temporary "Target Temp 1" will be
generated. This target is within a blocked region and rightly causes the output of an error
message.
The same applies if the "Target Hopper" is the next target to be specified after the "Target Ship"
is reached and the trolley target is changed first due to time delays.
For this reason, the target for the trolley must always be transferred first when targets are
changed above the hopper, and the target for the hoist always transferred first when targets are
changed above the ship. A temporary "Target Temp 2" will be generated as a result. This target
is not within a blocked region. No error message is output.
