| 摘 要： | LOGIDYN D2系统中的VCM232模板是系统内部的VMEbus的管理器，VCM232所管理的IEEEP1041标准VEMbus总线，使用二个连接器J1／P1、J2／P2，共有128个引脚。不仅有常规P1041所规定的ACFAIL，SYSRESET，SYSFAIL等信号线监视总线，另外在用户定区增设自定义的控制信号线，大大提或了VMEbus系统功能。从而丰富的对系统内部VMEbus即插即用模板的管理和硬件资源分配，使整个系统具有较高的性能较好的开发性。

| Abstract: | In the LogiDyn D2 system VCM 232 module is an internal manager of VMEbus in the management system. The VMEbus of IEEEP1041 standard regulated by VCM 232 uses two connectors J 1/P 1 and J 2/P 2 with a total of 124 lead-in pins. In the system are not only provided monitoring bus for ACFAIL, SYSRESET and SYSFAIL signals specified by the conventional P1041, but also self defined control signal line in the users defined area, and thereby the function of VMEbus system is greatly raised and the management of the internal VMEbus module of the system as well as the allocation of the hardware resources also improved.The whole system now advances to a more open system with higher performance. |
