VMIVME-4100的一个独特功能是内置测试逻辑,它允许
通过使用板载多路复用器和VMIVME-3100 ADC板测试任何一个模拟输出通道。在测试模式下,字段
通过连接器P3的连接可以被隔离,16个通道中的任何一个都可以
可以通过VMIC的模拟背板(AMXbusTM)路由到12位ADC板。
程序控制下的ADC板可以将模拟信号转换为
12位数字字,并与写入DAC的原始12位字进行比较
板通过这种方式,可以验证16个模拟输出通道中的每一个
不会干扰现场连接的设备。模拟输出通道可能
也多路传输至模拟测试总线,同时控制P3
连接现场设备,提供输出的实时故障检测。如果董事会
自检失败,前面板上的故障LED可能会亮起,以指示
电路板处于故障状态。完整的操作和要求
本手册第3节“理论”详细解释了自检模式
操作,以及第4节,编程。
A unique feature of the VMIVME-4100 is the Built-in-Test logic that allows
the testing of any one of the analog output channels through the use of an onboard multiplexer and the VMIVME-3100 ADC Board. When in test mode, the field
connections through connector P3 may be isolated and any of the 16 channels
may be routed to the 12-bit ADC Board via VMIC’s Analog Backplane (AMXbusTM).
An ADC Board under program control may have the analog signal converted to a
12-bit digital word and compared with the original 12-bit word written to the DAC
Board. In this manner, each of the 16 analog output channels may be verified
without disturbing the field connected devices. The analog output channels may
also be multiplexed to the Analog Test Bus, simultaneously controlling the P3
connected field devices, providing real-time fault detection of the outputs. If a board
fails its self-test, a Fail LED on the front panel may be turned on to indicate the
board is in a failed condition. The complete operation and requirements for the
self-test mode are explained in detail in this manual in Section 3, Theory of
Operation, and Section 4, Programming.
