7 Place the Sysmac Studio offline. Remove the USB cable from the EtherCAT Slave Terminal and
turn ON the power to the master from the other manufacturer.
8 Use the software from the other manufacturer to read the I/O allocation settings (PDO Map Set-
tings) for the EtherCAT Slave Terminal.
9 Use the software from the other manufacturer to create the network configuration information
(ENI) based on the EtherCAT Slave Terminal information that was read in the previous step.
Download the network configuration information file to the master from the other manufacturer.
(This operation is called active configuration.)
10 Turn ON the Unit power supplies and I/O power supplies for the EtherCAT Slave Terminal, and
start communications.
This section provides supplementary information that applies when you connect an EtherCAT Slave
Terminal to a master from another manufacturer.
The node address setting will contain the value that is set in the software from the other manufacturer.
This section describes the I/O map.
PDO Groups
There are three groups of PDOs. These are described in the following table.
PDO Group Mapping Order
Mapping is performed in the following order of PDO groups: Coupler, Word, and then Bit. Within the
PDO groups that the NX Units belong to, mapping is performed in the order of the NX Unit numbers.
PDO Group Boundaries
The areas that are mapped for the PDO groups are aligned by word.
