4. CONFIGURATION OF EtherCAT CONNECTION
4-11
4.1.4 EtherCAT slave setting
(1) I/O mapping setting
The following procedure shows how to allocate variables to the module I/Os you
configured.
1. Double-click EH_IOCA (EH-IOCA) under EtherCAT_Master (EtherCAT
Master) in the Devices window. Then, click EtherCAT I/O Mapping. As an
example, a UINT variable is allocated to Output. (Alternatively, you can click ... and
specify a variable you have already created.)
You can also allocate a BOOL variable to each Bit of the module you configured.
If you do so, however, you cannot use the UNIT variable allocated above.
