This paper presents the design and implementation of MIB for SNMP-based PLC system which is applicable to communication for railway vehicles. The proposed MIB has four nodes which are "Basic Information", "Configuration", "Stats", and "Alarm." The essential peripheral functions for "Alarm" to improve the performance of PLC are deyised. ACF is for auto connecting devices without intervention of the user. DEC is for checking the loss of data and the presence of error. DLPF is for preventing the loss of data and error To evaluate the proposed system, the experimental set-up is developed and the experiments are successfully carried out. The conclusion points out that the suggested MIB contributes the betterment of the conventional PLC systems.
