You can configure the scanner module to act as a DP slave to another DP
master on the same network.
For example, use this feature to pass data in a distributed system or to pass
data to or from an operator interface. The DP slave operation can only be
configured from the serial port.
7.1
Slave Received Data
Received data is data received from the remote master. You can have from 0
to 122 words of received data. Received data can be configured to be partly in
the input file and partly in the M1 file. You can put up to 32 words of
received data in the input file. You can choose to put all the received data in
the M1 file. Data in the input file can be accessed more quickly than data in
the M1 file but the more DP slave data you put in the input file, the less input
data you can scan with the module acting as a DP master.
DP slave received data in the M1 file always starts at offset 1000.
To set the received data length and location, use the SlvRxLen command.
SlvRxLen <io> <il> <ml>
<io> is the offset of the received data in the input file (0-31)
<il> is the length of received data in the input file (0-32)
<ml> is the length of received data in the M1 file (0-122)
Enter all three parameters.
Example
If you enter:
SlvRxLen 30 2 10
there will be two words of received data in the input file starting at offset 30
and ten words of received data in the M1 file starting at offset 1000. There are
a total of 12 words of received data.
Note
The scanner module does not check for address conflicts
between the DP master and DP slave operations. You are
responsible for ensuring that addresses have been assigned
without conflicts or overlaps.
