Zusammenfassung: | PURPOSE: To obtain the system suitable for high speed data exchange by the efficient control system. CONSTITUTION: Upon the receipt of a BOM, a destination address DA of an L3-PDU stored in a pay load of the BPM is extracted and tag information is found out from the DA (S11). In this case, an output message identifier MID is reserved (S12) and the tag information and an outgoing mID are given to the BOM (∫13). Furthermore, the tag information and the outgoing MIS are written in a table by using a MID 'incoming MID' as a key when the BOM is received. Upon the receipt of a COM, the tag information and the outgoing MID are extracted by using the MIS of the COM as a key and the information is given to the COM (S31, 32). Upon the receipt of an EOM, the tag information and the outgoing MID are extracted by using the MID of the EOM as a key and the information is given to the EOM (S41, 42). Then the outgoing MID is released (S43). |
