You can connect a maximum of 30 Sensor Amplifiers. (Refer to "2-2-2 Number of Connected Sensor
Amplifiers" on page 2-3.)
You can connect a maximum of eight Distributed Sensor Units to the E3NW-ECT.
The following table lists the items that you can assign to the E3NW-ECT.
You can assign a maximum of 350 bytes of PDOs. (Refer to "7-2-3 Mode Setting Functions for PDO
Communications" on page 7-6.) Refer to "A-1-5 PDO Mapping Object" on page A-7 for detailed object
specifications.
Refer to the specific manual for your master for information on changing the PDO mappings.
