Software
Primary side
Select the slave of the ECX-EC primary side:
Slave 1 (ECX-EC Pri)
(Fig. 6) and go to the
corresponding Workbench configuration tab (Fig. 7).
Right-click in the list of
Inputs:
to open a context menu and select
Append item
to append a new
input variable:
Fig. 9:
Edit input variable, EtherCAT Workbench
Choose “UDINT”, “32 bit” and name the variable “Variable1” as shown in Fig. 9.
Now create two output variables in the list
Outputs:
:
1. “USINT”, “8 bit” and “Variable1”
2. “UDINT”, “32 bit” and “Variable2”
Make sure that the variables are the same as those described in Fig. 7.
Secondary side
Select the slave of the ECX-EC secondary side:
Slave 2 (ECX-EC Sec)
(Fig. 6) and go to the
corresponding Workbench configuration tab (Fig. 8).
Because the input variables of one side must correspond to the output variables of the other side
two input variables must be created under
Inputs:
1. “USINT”, “8 bit” and “Variable1”
2. “UDINT” “32 bit” and “Variable2”
and one output variable under
Outputs
:
1. “UDINT”, “32 bit” and “Variable1”
Continue analogous to the creation of the variables on the primary side and make sure that the
variables correspond to those shown in Fig. 8.
