Operation Using a Programmable Logic Controller (PLC)
Read Read Read Event Event Event Info Info Info
The Read Event Info command allows remote access to any of the last 200 events logged by the ProMix PD2K.
The argument is the
chronological index
of the events log, where 0 is the most recent event and 199 is the 200 th
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 event code is a four-character little endian ASCII string.
The example decoding algorithm provided above for the Alarm Code may be used for Events equivalently.
Example: Read back the fifth most recent event, which was a Setup Value(s) Changed (EC00) recorded on Tuesday
June 3, 2014 at 8:11 AM.

Totals
The Read Grand Totals command allows remote access to the material grand total volume data. No arguments
are necessary for this command.
Example: Read current Grand Total usage data. A = 132 gal, B = 128 gal, A+B = 260 gal, Solvent = 11 gal
