The connection of the I/O modules of the family to the bus requires their address to be defined on the Fipio bus. This addressing must be carried out physically on the module using Control Expert software (
hardware configuration mode).
This addressing uses two thumbwheel switches and enables up to 98 I/O modules (1 to 62 and 64 to 99) to be connected to the bus.
The thumbwheels are protected in an M23 connector located to the bottom right of the module and the protective plug of the thumbwheels is attached to the module by a small chain.
Address 0 is reserved for the Fipio bus controller and address 63 is reserved for the connection of the programming terminal.
The figure below shows the two thumbwheels when the plug has been removed:
The code is read directly, the most significant value (tens) is on the left and the least significant value (units) is on the right.
After changing the code, the plug must be screwed back in place correctly and the Fipio connection replaced to ensure that the module is sealed.
