what's a normal map?
I am nearly ready to upload a remake of an old item from long ago that fell out of use as it did not function properly as of late.
When you wish to set up a simple crossing or other such feature and do not need the headache or level of control that comes with setting up the full EIT system with paths and such you can use this little item. It works by setting up a shared block with a list of signals and will cause the configured signals to share occupancy detection with 2 simple rules:
1. If a signal detects a train in it's block all signals in the list will be set to red.
2. If a train clears a path through one of the signals, the remaining in the list will be set to red.
For a diamond crossing situation, it can be set as follows using 2 controllers and linking 2 entries to the block on one and 2 on the other:
There are many other possible combinations and set-ups and is a very flexible item, but the item will not stop you from making a mistake in your choice, so for instance if you set 2 opposing signals to share a block you are making an impossible situation where they can never clear. Maybe later on there can be fail-safes against that, but just don't do it, it makes no sense anyway.
