Information that you will in this
chapter …
This chapter shows you how to implement a fieldbus coupling for the "Comfort Reference
Value" application. When you connect a fieldbus, be sure to:
• select the appropriate device controller in the configuration assistant,
• install the appropriate option board if you are using CAN, PROFIBUS DP or EtherCAT
and
• configure the option in the configuration assistant.
You will be provided with an assistant in the global sector for the configured fieldbus.
You can access the fieldbus parameters such as bus address or mapping parameters
with this assistant.
The control and status words
You can write binary signals to the inverter in the "Comfort Reference Value" application
via the control words:
• A180 device control byte,
• D210 speed reference value control word,
• D211 speed reference value control word 2 or
• D212 speed reference value control word 3.
You can specify in the selector of a signal whether the signal is to be written via a binary
input or fieldbus. If you use transmission via fieldbus, set 2:parameter in the selector.
The description of the selector tells you which control word and which bit has to be
written.
The following parameters are available as status words.
• E200 device status byte,
• D200 speed reference value status word,
• D201 speed reference value status word 2 and
• D202 speed reference value status word 3.
You do not have to allocate the status words to bits like you do for the control words. The
signals are automatically written to the bits.
In online mode you can monitor the control and status words on pages 17 to 20 of the
"Comfort Reference Value" assistant.
When you connect
a CAN bus
The CAN fieldbus interface provides you with the following:
• Two PDO channels (tx / rx).
• One SDO channel (tx / rx).
• If necessary, three additional SDO channels (tx / rx).
Cf. CANopen documentation, impr.-no. 441684.
When you connect
a PROFIUS DP
The PROFIBUS DP fieldbus interface provides you with the following:
• GSD file
• PPO 1: 4 PKW, 2 PZD
• PPO 2: 4 PKW, 6 PZD
• PPO 3: 0 PKW, 2 PZD
• PPO 4: 0 PKW, 6 PZD
• PPO 5: 4 PKW, 10 PZD
• Support of the DP-V1 protocol
Cf. PROFIBUS DP documentation, impr.-no. 441685.
When you connect
an EtherCAT fieldbus
The EtherCAT fieldbus interface provides you with the following:
• Two PDO channels (tx / rx).
• One SDO channel (tx / rx).
Cf. EtherCAT documentation, publ.-no. 441896.
