  • Page 8: Anatel ® Pat700 Analyzer Overview

    Before you begin ® 1.2 Anatel PAT700 analyzer overview ® The Anatel PAT700 analyzer provides TOC analysis for pure and ultra-pure water processing. The PAT700 oxidizes a water sample to determine the TOC in the sample. The analyzer traps a sample in the analysis cell, exposes the sample to ultraviolet (UV) light, and monitors changes in temperature and conductivity until the sample has completely oxidized.

  • Page 92: Toc Calibration

    Bottle Mode 6.5 TOC calibration TOC calibration ensures the accuracy of the TOC values obtained by the analyzer. TOC values are determined by measuring the change in conductivity of a high-purity water sample as its organic compounds oxidize to carbon dioxide inside the analysis cell. The procedure subtracts the average of a series of background TOC measurements from the average of a series of user-selected standard measurements (in the form of sucrose).

    Modbus Protocol 11.3 Data encoding Modbus uses a 'big-endian' representation for addresses and data items. This means that when a numerical quantity larger than a single byte is transmitted, the MOST significant byte is sent first. The following sub-topics describe the different types of encoding and show how the data is encoded as it is within the Modbus/TCP packet.
  • Page 152 Modbus Protocol Double A Double float value is 64-bits within the Anatel PAT700 TOC Analyzer. FC3 reads 16-bit items at a time; therefore, four registers are required to read each Double float data item. Note: The Modbus/TCP protocol follows Little Endian - byte swap format while transmitting Double float data i.e.
  • Page 153 Modbus Protocol Date The Date is transmitted similar to a 32-bit Word with the MOST significant byte first, then the next MOST significant, until all the bytes are transmitted.
