E: Retrieving Logs Using the MP200 Metering
System's Modbus Map
E.1: Overview
This appendix describes the log interface system of the MP200 unit from a
programming point of view. It is intended for programmers implementing indepen-
dent drivers for log retrieval from the MP200 unit. It describes the meaning of the
MP200's Modbus Registers related to log retrieval and conversion, and details the
procedure for retrieving a log's records.
NOTES:
• All references assume the use of Modbus function codes 0x03, 0x06, and 0x10,
where each register is a 2 byte MSB (Most Significant Byte) word, except where
otherwise noted.
• The carat symbol (^) notation is used to indicate mathematical "power." For
example, 2^8 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2, which equals 256.
