Introduction to Fipio communication
Addressing of Remote Module Language Objects on a FIPIO Bus
At a Glance
The addressing of the main bit and word objects of remote modules on the Fipio bus is performed on a geographical basis. That means that it depends on:
The connection point,
The type of module (base or extended),
The channel number.
Illustration
Addressing is defined in the following way:
