About the connection between IFD9503 and PLC, IFD9503 and ASD-B, or IFD9503 and other equipment,
please refer to Chapter 13. For the electrical specifications of ASD-B, please refer to ASD-B user manual.
4.2 Data Mapping in CANopen Network
z Data mapping in DVP-12SA
DVP-08ST, connected on the right hand side of DVP-12SA, offers 8 channels of digital input and 1 byte of
input data. In this example, we will use X0 and X1 on DVP-08ST to RUN/STOP ASD-B and select speed. Y0 is
for the output signal of ASD-B operational status. See the table below for more information.
Channel Function
X0 Controlling RUN/STOP of ASD-B
X1, X2
Selecting the speed of ASD-B:
X2 = 0, X1 = 1, selecting SP1
X1 = 1, X2 = 0, selecting SP2
X1 = 1, X2 = 1, selecting SP3
Y0
Operational status of ASD-B:
On: RUN
Off: STOP
Supposed IFD9503 is connected to DVP-12SA and exchanging data with DVPCOPM-SL master, the default
length of input data is 8 bytes and output data is 8 bytes. D256 in DVP-12SA is the start device for input data,
and D0 is the start device for output data. To realize the control function of X0, X1 and X2, we place the
statuses of X0 ~ X2 to bit 0 ~ 2 of D256. That is, when X0 = On, bit 0 of D256 will become 1. When X1 = On, bit
1 of D256 will become 1. In this way, we can realize the control of RUN, STOP and speed of ASD-B by the
changes in D256 through WPLSoft. The status word in ASD-B will then be sent to D0. That is, when bit 0 of D0
becomes 1, there will be signals at Y0.

z Data mapping in ASD-B
In this example, IFD9503 is the interface between ASD-B and CANopen network. In default setting, IFD9503
offers 1 word of input data and 1 word of output data to exchange data with DVPCOPM-SL master. See the table
below for the relation between the parameters in ASD-B and the input and output data in DVPCOPM-SL master.
