PFEA112-65 3BSE050091R65控制器，ABB英文使用说明

安装远程开关和电缆后，MVME147可以通过远程开关或前面板重置开关重置。故障指示器（DS1）红色故障指示灯DS1指示BRDFAIL位的状态VMEchip。当设置BRDFAIL位或当PCC中出现看门狗超时时。此外，如果故障指示灯为未设置VMEchip中的lit和SYSFAIL抑制位，MVME147VMEbus上的驱动器SYSFAIL。状态指示器（DS2）每当MC68030启动时，黄色状态LED DS2亮起状态*引脚低。

PFEA112-65 3BSE050091R65控制器当黄色LED完全点亮时，处理器已停止。绿色运行指示灯DS3连接至MC68030地址选通（AS*）信号，指示微处理器正在执行总线周期SCON指示器（DS4）当MVME147为VMEbus系统控制器。表3-1。前面板指示灯和MVME147状态（绿色）MVME147状态off off off模块未通电，或MPU不是当前本地总线主节点。关闭-关闭-打开MPU正在等待一个循环完成。off ON（亮）off MPU暂停。off ON（正常）off MPU仅在其片上缓存中执行。正常运行时关闭打开。开-关-关MPU不是当前的本地总线主机，并且未执行芯片缓存不足。此外，[BRDFAIL]尚未重置后清除或已由软件设置。ON off ON[BRDFAIL]自重置后未清除或已设置通过软件。此外，MPU正在等待一个周期的完成。ON ON（亮）off MPU暂停，[BRDFAIL]此后未被清除重置或已由软件设置。ON ON（normal）off[BRDFAIL]自重置后未清除或已设置通过软件。此外，MPU在片上缓存外执行只有ON ON ON[BRDFAIL]自重置后未清除或已设置通过软件。

When the remote switch and cable is installed, the MVME147 can

be reset by the remote switch or by the front panel RESET switch.

FAIL Indicator (DS1)

The red FAIL LED, DS1, indicates the status of the BRDFAIL bit in

the VMEchip. The FAIL LED lights when the BRDFAIL bit is set or

when watchdog time-out occurs in the PCC. Also, if the FAIL LED is

lit and SYSFAIL inhibit bit in the VMEchip is not set, the MVME147

drives SYSFAIL on the VMEbus.

STATUS Indicator (DS2)

The yellow STATUS LED, DS2, lights whenever the MC68030

STATUS* pin is low. When the yellow LED is fully lit, the processor

has halted.The green RUN LED, DS3, is connected to the MC68030 address

strobe (AS*) signal and indicates that the MPU is executing a bus

cycle.

SCON Indicator (DS4)

The green SCON LED, DS4, lights when the MVME147 is the

VMEbus system controller.

(Green) MVME147 Status

off off off No power is applied to the module, or the MPU is not the

current local bus master.

off off ON MPU is waiting for a cycle to complete.

off ON (bright) off MPU is halted.

off ON (normal) off MPU is executing out of its onchip cache only.

off ON ON Normal operation.

ON off off MPU is not current local bus master and is not executing

out of onchip cache. Also, [BRDFAIL] has not been

cleared since reset or has been set by software.

ON off ON [BRDFAIL] has not been cleared since reset or has been set

by software. Also, MPU is waiting for a cycle to complete.

ON ON (bright) off MPU is halted and [BRDFAIL] has not been cleared since

reset or has been set by software.

ON ON (normal) off [BRDFAIL] has not been cleared since reset or has been set

by software. Also, MPU is executing out of onchip cache

only.
