ALSTOM MLU VER.A01 Industrial spare parts module of Alstom processor
Diagnostics for ALSTOM MLU VERA01 master Processor diagnostics verify the health of each master processor as well as each /0 module and communication channel. Transient faults are recorded and shielded by the hardware majority voting circuit. ALSTOM MLU VER.A01 diagnoses persistent faults and performs hot replacement or fault tolerant operations on faulty modules until the hot replacement is complete.
ALSTOM MLU VER.A01 main processor diagnostics includes the following functions :· Verify fixed program memory · Verify the static portion of RAM Test all basic processor instructions and modes of operation · Test all basic floating point processor instructions · Verify shared memory interface with 1/0 processor · Verify each /O processor, communication processor, local memory, shared memory access, Loop back and RS-485 transceivers · Verify ALSTOM MLU VER.A01 interface · Verify Tribus interface The standard 25-pin external threaded D connector (RS-232) at the bottom of each MP operates at 9600 bits per second, ALSTOM MLU VER.A01 indicates that this interface can be used for diagnostic analysis. RS.232 ports are fully isolated (500 VDC) to provide ground fault protection.
