DM-0013_Digital Process Recorder (DPR)_IOM_Rev2.0

3. SaniTrend Cloud DPR Communications Instructions For any data not hardwired directly into the analog or digital inputs, below is an overview of communication instructions needed.

For PLC-to-PLC communication, the following must be added to the customer’s Allen Bradley ControlLogix® / CompactLogix™ series processor:

• For Analog data collection over communications:

o Globally scoped array of REAL tags with a length of 8 (REAL[8]). o Populate the array with the different analog values being recorded.

• For Digital data collection over communications: o 1 Globally Scoped DINT tag. o Populate the individual bits of the double integer for each digital value recorded.  IMPORTANT NOTE

• If using the SaniTrend Cloud DPR Reports automated cycle report feature, there must be one digital input that is energized while the process data cycle is running. This bit turning on indicates the start of the process data cycle, and the bit turning off indicates the end of the process data cycle.

• For Recipe/Wash Cycle Name (SaniTrend Cloud DPR Reports Only) o 1 Globally Scoped String Tag. o Populate this string tag with the name of the process data cycle (if applicable). The following images are representative examples of the above communications setup:
