Planning Module Location
The 1771-M3 controller requires one I/O chassis slot. You can install it in
any I/O in the I/O chassis. The 1771-M3 controller uses both the output
image table byte and the input image table byte that correspond to its
location address.
The 1771-ES expander requires two slots. Install it in a pair of slots that
make up an I/O module group.
Through switches and jumpers on the 1771-ES expander, you can select
various aspects of the module’s operation. To access these switches and
jumpers, lay the 1771-ES expander on its right side and remove the left
cover. Locate the switches and jumpers through Figure 6.1.
