A.1 What this chapter contains
This chapter describes the extension cards used in Goodrive35 series inverters.
A.2 PROFIBUS/CANOPEN extension card
(1) PROFIBUS/CANOPEN 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/CANOPEN is composed of three compatible components,
PROFIBUS/CANOPEN-DP (Decentralized Periphery, distributed peripherals),
PROFIBUS/CANOPEN-PA (Process Automation), PROFIBUS/CANOPEN-FMS (Fieldbus
Message Specification). It is periodically exchange data with the inverter when using
master-slave way. PRNV PROFIBUS/CANOPEN-DP Adapter module only supports
PROFIBUS/CANOPEN-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/CANOPEN network when repeaters aren't used. But, if use repeaters, up
to 127 nodes can be connected to the same PROFIBUS/CANOPEN network segment
(including repeaters and master stations).
(4) In the process of PROFIBUS/CANOPEN 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/CANOPEN network, communication between nodes can not be allowed.
(5) PROFIBUS/CANOPEN protocol is described in detail in EN 50170 standard. To obtain
more information about PROFIBUS/CANOPEN, please refer to the above-mentioned EN
50170 standards.
