Module Identification Parameters P794 and P795 are used together to identify the module type and protocol used. P794 SmartLinx Module Type (Read only) Identifies the module used. P795 SmartLinx Protocol (Read only) Identifies the protocol used: the value varies according to the module, and whether it is a type 1 or type 2.
