8.4 I/O assemblies
The Communication Unit supports the Assembly Object (4 / 0x04) ( 114) and the "AC Drive Profile"
objects ( 133).
For data exchange, the Communication Unit supports the following assembly object instances:
Assembly output objects (outputs) are usually used for controlling the enable/disable state of the
inverter and for supplying the speed or torque references.
Assembly input objects (inputs) are usually used to monitor the drive status and the runtime values
such as actual speed, current, actual position and position error.
Depending on the data length defined by the scanner, the memory map of the I/O data can have
different sizes.
Note!
The terms "input" and "output" refer to the point of view of the scanner:
• Assembly input objects (input) are sent from the adapter to the scanner.
• Assembly output objects (output) are sent from the scanner to the adapter.
The length of the I/O data must correspond with the respective resulting length of the
mapped ports (I/O data mapping
( 48)).
