A.1 What this chapter contains
This chapter describes the extension cards used in Goodrive300 series inverters.
A.2 PROFIBUS extension card
(1) PROFIBUS is an open international fieldbus standard that allows data exchange among
various types of automation components. It is widely used in manufacturing automation,
process automation and in other automation areas such as buildings, transportation, power,
providing an effective solution for the realization of comprehensive automation and
site-equipment intellectualization.
(2) PROFIBUS is composed of three compatible components, PROFIBUS-DP
(Decentralized Periphery, distributed peripherals), PROFIBUS-PA (Process Automation),
PROFIBUS-FMS (Fieldbus Message Specification). It is periodically exchange data with the
inverter when using master-slave way. PRNV PROFIBUS-DP Adapter module only supports
PROFIBUS-DP protocol.
(3) The physical transmission medium of bus is twisted-pair (in line with RS-485 standard),
two-wire cable or fiber optic cable. Baud rate is from 9.6Kbit/s to 12Mbit/s. The maximum
bus cable length is between 100 m and 1200 m, specific length depending on the selected
transmission rate (see chapter Technical Data). Up to 31 nodes can be connected to the
same PROFIBUS network when repeaters aren't used. But, if use repeaters, up to 127
nodes can be connected to the same PROFIBUS network segment (including repeaters and
master stations).
(4) In the process of PROFIBUS communication, tokens are assigned among main stations
and master-slave transmission among master-slave stations. Supporting single-master or
multi-master system, stations-programmable logic controller (PLC)-choose nodes to
respond to the host instruction. Cycle master-from user data transmission and non-cyclic
master-master station can also send commands to multiple nodes in the form of broadcast.
In this case, the nodes do not need to send feedback signals to the host. In the PROFIBUS
network, communication between nodes can not be allowed.
(5) PROFIBUS protocol is described in detail in EN 50170 standard. To obtain more
information about PROFIBUS, please refer to the above-mentioned EN 50170 standards.
