Communication Data Formats

This chapter expands upon information listed in the EPM Modbus Register Map (Chapter 2). Section Headings (F1, F2, etc) refer to the value in the Register Map’s “Type” column.

3.1: Type F1 Null Terminated ASCII String

Length: Depends on the reading.

Each register contains two bytes. Each byte stands for an ASCII character. The printable portion of the string is terminated with a Null character (ASCII 00H). Any characters after the terminating Null are ignored.

Example:

Registers 00001 – 00008, the Device Name, might contain the following data:

3.2: Type F2 Fixed Length ASCII String

Length: Depends on the reading.

Each register contains two bytes. Each byte stands for an ASCII character. All bytes are significant. There is no terminating character.

Example:

Registers 00073 – 00074, the EPM Comm Boot Version Number, might contain the following data:
