EMERSON KJ4001X1-BE1输出模块DCS卡件
远程启动如附录B“相关文档”中列出的MOTLoad固件包用户手册所述，远程启动允许用户获取有关目标板的信息、下载代码和/或数据、修改目标上的内存并执行下载的程序。在MVME7100的情况下，这些交易发生在VMEbus上。MOTLoad使用Tsi148 VME控制器中的四个邮箱之一作为主机和目标之间的板间通信地址（IBCA）。MOTLoad配置的CR/CSR从机地址根据背板中的安装槽分配，如VME64规范所示。为参考，提供了以下值：表6-2 CR/CSR从属地址有关CR/CSR空间的更多详细信息，请参阅附录B“相关文档”中列出的VME64规范。MVME7100使用TSi148作为其PCI/X-VME总线桥。TSi148中邮箱的偏移量在附录B“相关文档”中列出的TSi148 VMEBus PCI/X-to-VME用户手册中进行了定义，但在此进行了注释以供参考：邮箱0在CR/CSR空间中的偏移量为7f610邮箱1在CR/CR空间中的位置为偏移量7f614邮箱2在CR/CRS空间中的距离为7f618邮箱3在CR/CCR空间中的偏差为7f61C
Remote Start
As described in the MOTLoad Firmware Package User's Manual, listed in Appendix B,
Related Documentation, remote start allows the user to obtain information about the target
board, download code and/or data, modify memory on the target, and execute a
downloaded program. These transactions occur across the VMEbus in the case of the
MVME7100. MOTLoad uses one of four mailboxes in the Tsi148 VME controller as the
inter-board communication address (IBCA) between the host and the target.
CR/CSR slave addresses configured by MOTLoad are assigned according to the
installation slot in the backplane, as indicated by the VME64 Specification. For reference,
the following values are provided:
Table 6-2 CR/CSR Slave Addresses For further details on CR/CSR space, please refer to the VME64 Specification, listed in
Appendix B, Related Documentation.
The MVME7100 uses a TSi148 for its PCI/X-to-VME bus bridge. The offsets of the
mailboxes in the TSi148 are defined in the TSi148 VMEBus PCI/X-to-VME User Manual,
listed in Appendix B, Related Documentation, but are noted here for reference:
Mailbox 0 is at offset 7f610 in the CR/CSR space
Mailbox 1 is at offset 7f614 in the CR/CSR space
Mailbox 2 is at offset 7f618 in the CR/CSR space
Mailbox 3 is at offset 7f61C in the CR/CSR space
