15.4 Universal Serial Interface Protocol - USIP
Use and Application
The u niversal s erial i nterface p rotocol USIP of the FCS01 series is used
to control and parameterize the converter via an asynchronous serial
interface.
To establish a point-to-point communication via the USI protocol, use
interface RS-485 at the top of the device.
By means of the control and commissioning program DriveTop Fc , the
devices can be commissioned through a PC.
USI Protocol
Supported by the USI protocol, the user can establish a serial bus
coupling between a superimposed master and several slave systems.
Master systems can for example be memory-programmable controls
(PLCs) or PCs.
The USI protocol allows the user to realize automation tasks which
demand a time-cyclic telegram traffic (
⇒
fixed telegram length required),
as well as visualization tasks.
The USI protocol is a simple serial transmission protocol defined by
Siemens which is tailor-made for the requirements of drive engineering.
•
master-slave access method
•
Single master system
•
Simple, safe telegram frame
•
Data interface to the basic device after PROFILE variable-speed
drives, i.e. information on the drive are transmitted via the USI protocol
in the same way as with PROFIBUS DP.
•
Suitable for commissioning, service and automation
