DIT are mapped into the P3 CPU’s Data Interchange Table address space, and so may
be directly addressed as if these registers are part of the CPU.
Any programming or configuration for an Intelligent Module is stored in non-volatile
memory in the module itself, and not in the CPU. If an Intelligent Module is exchanged,
then the replacement module must be re-configured/reprogrammed. This can be done
throug
h the CPU’s programming port.
An example of an Intelligent Module is any one of the range of Network Interface
Modules (NIM’s). NIM’s can be considered as an extension of the CPU’s network ports.
Most NIM’s are user programmable, so that custom protocols or data manipulation
algorithms may be written for the NIM and executed in the NIM to remove processing
overhead from the P3 CPU.
