Read Alarm Info

The Read Alarm Info command allows remote access to any of the last 200 alarms logged by the ProMix PD2K. The argument is the chronological index of the alarm log, where 0 is the most recent alarm and 199 is the 200th most recent.

The date is returned as a four-byte packet with each byte holding a two-digit value for (from MSB to LSB) year, month, day, and day of the week (Monday = 01).

The time is returned as a three-byte packet with each byte holding a two-digit value. Starting from the MSB, the ﬁrst byte can be ignored, then hour, minute, and second.

The alarm code is a four-character little endian ASCII string

See System Errors, page 88, for more details on these Event Types. An example decoding algorithm is provided below.

Example: Read back the second most recent alarm, which was a Position Pump 1 (DK01) recorded on Tuesday June 3, 2014 at 8:11 AM.

Return 0	Alarm Date	uint32	[YY:MM:DD:DW]	0x0E060302 =	N/A

Return 1	Alarm Time	uint32	[xx:HH:MM:SS]	0x080B0B =	N/A

Return 2	Alarm Code Char[3:0]	uint32	NONE	0x31304B44 = [‘1’,	N/A
				’0’, ’K’, ’D’]
Example ASCII Character String Decode Algorithm:
character_str[0] = Return_2 & 0xFF;
character_str[1] = (Return_2 >> 8) & 0xFF;
character_str[2] = (Return_2 >> 16) & 0xFF;
character_str[3] = (Return_2 >> 24) & 0xFF;
character_str[4] = ‘\0’;
