2.4 Basic function principles
The 4-axis interface terminal module EM7004 integrates 4 Incremental encoder, 4 analog outputs with
+/-10 V and 16 digital 24 V inputs and outputs. The digital inputs and outputs can be connected in single, two
or three wire connection mode.
For the incremental encoder a 16-bit counter with quadrature decoder and a 16-bit latch can be read, set or
enabled. In addition to encoder inputs A, /A, B, /B, an additional latch input L (24 V) and a gate input G
(24 V) for disabling the counter are available. The "Value" input value represents a 16-bit "position counter".
The PLS function (Programmable Limit Switch) can be used to control digital outputs automatically
depending on the encoder counter value (up to 75 entries).
