1. INTRODUCTION
This Document is a fully descriptive operational manual for PMM’s Industrial Modbus Data Logger.
Providing the operator with the needed information in terms of instruction and screen layout of the monitors,
allowing for easy use.
PMM0203 data logger has Multiple Modbus channels let you interface with many different Modbus
registers; the user has to specify the device address and register address numbers for each channel. Use the
setup screen to configure what data to log, the data logging interval, the scale factor for each Modbus register,
and save the entire configuration screen to an external file for later use. Data is logged in real time so to
minimize chances of data loss due to external problems. File names include the date and time the file was
created along with optional user specified text. New log files are automatically created when the maximum
file size is exceeded, allowing the program to gather data for an almost unlimited amount of time without
stopping the program.
PMM0203 data logger has an onscreen data trending graph displays real-time data as it is read from
the Modbus slave devices. Zoom into data on the graph using one of the 3 window zoom features. Pan the
graph to view the data as it changes. Specify the minimum and maximum axis values and Y Axis titles via the
graph options button. Set the graph to automatically pan with time so that the latest data is always visible.
Preform all of these functions while the graph updates with the latest data.
PMM0203 can be contained within multiple hardware chassis such as PMM0102, PMM0103, PMM0105,
PMM0107, PMM0108 and PMM0109 in this document PMM0103 and PMM0105 are mentioned as
illustration example. The CPUs are designed with a wide range of highly configurable communication ports
needed in the field. All hardware chassis are rugged, powerful, reliable, fanless and cover a wide range of
power supply options that offer a high level of performance and low level of power consumption. The system
is especially designed to meet all power substation requirements. Furthermore, it covers all field standards of
power, reliability, easy configuration and long-lasting life.
