There are many ways to get charting:
1) If you purchase a SCADA software (from vendors of Lookout, Interllusion or Wonderware etc) which has a MODBUS driver, you should be able to capture the data and put them on charts.
2) You can write your own software to capture the data using the hostlink commands to talk directly to the PLC via the serial port.
3) You can use the email capability of the Internet TRiLOGI server to email the data collected over a period of time. The T100MD PLC can save up to 4000 16-bit words of data in RAM and another 1700 words in EEPROM. The data can be formatted into text string to be emailed to anywhere you like. The collected data can then be read into Excel and produce a chart.
3) We can supply Java library class files for Java programmers who can then easily log on to TLServer via the Internet and collect data and produce the chart on their own software.
