Addressing the extension modules
The extension modules are equipped with DIP switches for communication with the
controller. Switches 1, 2, 3, 4, and 5 are configurable to set the slave address,
while switch 6 acts as peripheral bus termination. When the extension module op-
erates as the termination in the network, switch 6 must be set to ON.
By combining switches 1, 2, 3, 4 or 5, a maximum of 31 slave addresses can be
configured. Below are some configuration examples:
