To assemble a multi-tier configuration, follow these steps:
1. Install the BaseUnit BU-Send to the immediate right of the ET 200SP CPU/interface
module.
When the BaseUnit BU-Send is used next to the ET 200SP CPU, a CM DP and an
Ethernet CP or a maximum of 2 Ethernet CPs can be inserted between the CPU and BU-
Send.
2. Then mount the additional BaseUnits / I/O modules for the ET 200SP distributed I/O
system and the server module.
3. Connect the bus cable for ET-Connection to the BusAdapter BA-Send 1xFC and mount
this on the BaseUnit BU-Send.
4. Screw the BusAdapter BA-Send 1×FC to the BaseUnit BU-Send (1 screw with 0.2 Nm
tightening torque). To do this, use a screwdriver with a 3 to 3.5 mm blade.
5. Connect the other end of the bus cable for ET-Connection (with M8 connector) to the first
ET 200AL I/O module (X30 socket ET-Connection IN).
6. Connect the supply voltage (24 V DC) to the ET 200AL I/O modules (X80 connector).
