Use as counter input on X3 to X6 
An available encoder input of an axis channel (e.g. for a speed-controlled axis) can be used 
as an input for a 16-bit up/down counter (90-degree pulse train of a connected TTL encoder, 
zero pulse not required). The counter value can be accessed by means of an I/O variable. 
Configuration procedure in SIMOTION SCOUT: 
1.  Specification of start address in the hardware configuration. 
 
 
2.  Use of the available encoder input as an additional counter using an incremental 
encoder.
