Data Types And Formats

The following table describes the possible return data types and formats for Modbus
registers defined in the CIM.
A register data value consists of two bytes: the most significant (MSB) and the least
significant (LSB). Data values are arranged with the MSB first (called big-endian).
Data Register Maximum
Type Count Range
0 or non-
boolean 1
zero
0 to max-
enum 1
range
uint8 1 0-255
uint16 1 0-65535
string n special
struct n special
