Ganz GXi Series VCA Interface Manual V3.05.31.18 Proximity Clause The 'proximity' clause adds the requirement for two inputs to an 'and' clause to have been triggered by targets that are detected at more than or less than some defined distance apart. The input clauses to be constrained are chosen using their clause id which is the number in square brackets at the start of the clause sentence on the web page. The 'proximity' clause can only be created as an input to an 'and' clause and can only refer to other inputs of the same 'and' clause. The example below shows how the 'proximity' clause constrains the output of the 'and' clause. The identities of the targets triggering the two presence rules are indicated by the red and green coloring. The logical rule in the example triggers when the distance value is less than two meters. The output event will end once the distance is more than 2 meters or either target is lost. 05-2018-A 58 | P a g e
