Note: Input registers 139 – 213 contain the fault history. The last 15 fault records are stored. Each record consists of 5 consecutive input registers; 1 input register holds the fault code, 2 input registers hold
the time stamp and 2 input registers hold the valve cycle count recorded at the moment of fault occurrence. The time stamp is recorded with resolution 0.25 hr.
The 4 time stamp / cycle count input registers for each fault contain a 32-bit value stored in mode 3-2-1-0. The input register with lower number contains the upper bytes of the 32-bit number (bytes 3 and
2) and the input register with higher number contains the lower bytes of the 32-bit number (bytes 1 and 0).
