5.3.3 Replacing DI modules by DIO modules
Digital I/O modules are available in two versions :
♦
DIO : each channel can be configured as Input or Output
♦
DI : each channel is an Input
DIO modules support all the functions of corresponding DI modules. So it is possible to replace a DI
module by a DIO module without modifying the Profibus configuration.
Replaceability simplifies stock keeping of spare parts. Installing DI modules is also a cost-effective
solution.
If you replace an installed and configured DI module by a DIO module, the bus node will automatically
recognize the DIO module and assure via the integrated replacement algorithm that it behaves like a DI
module for the DP master and the application.
