Introduction
Stun Technology:
Serial tunneling (serial tunnel) technology. The technology is to send the SNA packages from the FEP (3745/6) serial port to the router, the router is packaged into an IP packet and then transferred to the SDLC interface device after the router is routed to the target router and then SDLC to the SNA.
CIP technology: CIP-Channel Interface processor (Channel Interface Process

its identity mask are stored in the CAN message Ram. All protocol processing for data sending and receiving filtering is done by the CAN controller without CIP-51 intervention, which minimizes CPU interference for CAN communication.The CAN controller is a fully functional Bosch CAN module that fully complies with the can specifications 2.0a and 2.0b. The schematic diagram 2 of the CAN controller is shown in. The can core provides shift output, input
STUN Technology:
That is, the serial tunnel technology. This technology sends the SNA software package from the serial port of FEP (3745/6) to the vro, Which is packaged into IP data packets and then transmitted in the network composed of routers, then, the SDLC data packets restored to SNA are sent to the SDLC interface device after the router is split.
CIP technology:
CIP is the Channel Interface Proces
Some small things may be useful sometimes!

big mistake.(2). The initialization or copying of pointers can only be one of four types of values:(a). 0 value expressions, for example, 0 worth of Integer const objects or literal constants 0 are obtained at compile-time.(b). The address of the type-matching object.(c). The next address after another object.(c). Another valid pointer of the same type.5.void pointer : It can hold the address of any type of object.6.
