4.5.5 SmartWire-DT write response
The variable frequency drive/variable speed starter will respond to a received
SmartWire-DT write request with a SmartWire-DT write response.
The following SmartWire-DT write responses are possible:
• SmartWire-DT write re) – Without data or errors if the DC1
variable frequency drive has understood the SmartWire-DT write
request.
• SmartWire-DT write request(-) – Error. If an error has occurred, the write
response will contain an error. These errors are bus-specific and are
explained in the corresponding sections.
4.5.5.1 SmartWire-DT read request
After receiving a positive SmartWire-DT write response, it is possible to start
polling SmartWire-DT read requests. If a write job has been transmitted
previously, information regarding the write status will be requested; in the
case of a read job, the data will be requested.
4.5.5.2 SmartWire-DT read response
The SmartWire-DT read request will be acknowledged until there is a
SmartWire-DT read response.
The following SmartWire-DT read responses are possible
• SmartWire-DT read response(-) – Error
• If there is an error related to addressing (index)
• the variable frequency drive/variable speed starter is not available,
• if the response from the variable frequency drive/variable speed
starter is still pending
• SmartWire-DT read re) – Parameter channel error
• If the error concerns the PROFIdrive parameter channel
• SmartWire-DT read re) – Without data
• if the variable frequency/variable speed starter drive has determined
the reply during a write order
• SWD read re) – with data
• if the variable frequency drive/variable speed starter has determined
the reply during a rad order.
The following sections go into the various possible SmartWire-DT read
responses in greater detail.
