PROFIBUS-DP
•
PROFIBUS is an open field bus independent on the bender that is used for various applications in
factory automation and process automation.
PROFIBUS provides a communication protocol (communication profile) that supports system
hierarchy, i.e. DP and FMS.
•
When the V7 series is equipped with the communication interface unit CU-04 is mounted,
PROFIBUS-DP communications can be performed.
The V7 series can work as a slave station on PROFIBUS-DP.
A maximum of 12 Mbps is available (automatically set to the BUS baud rate).
The signal level is RS-485.
* The V7 series can only communicate with the master PLC.
•
PROFIBUS-DP supports I/O communications only.
With I/O communication, it is not possible to directly access the device memory (DB or MW) used
in the CPU. To enable the V7 series to have direct access to these memory devices, Hakko
Electronics' supplies the function (ladder file) for message communications. When this function is
loaded in the master CPU, message communications using Hakko Electronics' original protocol
are enabled, and the V7 series can have access to any memory address.
•
For the procedure of loading Hakko Electronics’ function, refer to the Specifications for
Communication Unit “PROFIBUS-DP.”
