E50C1 Installation Guide

Modbus Point Map 
Overview

The E50C1 Basic Data Set (BDS) features Wh and VARh accumulators. The meter supports variable CTs and PTs, allowing a much 
wider range of operation from 90V x 5A up to 32000V x 32000A. To promote this, the meter permits variable scaling of the 16-bit 
integer registers via the scale registers. The 32-bit floating point registers do not need to be scaled.

Integer registers begin at 001 (0x001). Floats at 257 (0x101). Configuration registers at 129 (0x081). Values not supported in a 
particular System Type configuration will report QNAN (0x8000 in Integer Registers, 0x7FC00000 in Floating Point Registers).

Supported Modbus Commands

Note:  ID String information varies from model to model. Text shown here is an example.

Report ID
Return string:
byte0:   address
byte1:   0x11
byte2:   #bytes following w/out crc
byte3:   ID byte = 247
byte4:   status = 0xFF if the operating system is used; status = 0x00 if the reset system is used
: ID string = “Veris Industries E50xx Power Meter Full Data Set”  or “Veris Industries E50xx Power Meter - RESET 

SYSTEM RUNNING RS Version x.xxx” last 2 bytes: CRC

0x2B

Read Device Identification, BASIC implementation (0x00, 0x01 and 0x02 data), Conformity Level 1.
Object values:
0x01: “Veris Industries”
0x02: “ E50xx”
0x03: “Vxx.yyy”, where xx.yyy is the OS version number (reformatted version of the Modbus register #7001, (Firmware 

Version, Operating System).  

If register #7001 == 12345, then the 0x03 data would be “V12.345”).

Legend

The following table lists the addresses assigned to each data point. For floating point format variables, each data point appears 
twice because two 16-bit addresses are required to hold a 32-bit float value.

R/W 

R=read only; R/W=read from either int or float formats, write only to integer format.

NV

Value is stored in non-volatile memory. The value will still be available if the meter experiences a power loss and reset. 

Format

UInt

Unsigned 16-bit integer.

SInt

Signed 16-bit integer.

ULong

Unsigned 32-bit integer; Upper 16-bits (MSR) in lowest-numbered / first listed register (001/002 = MSR/LSR).

Float

32-bit floating point; Upper 16-bits (MSR) in lowest-numbered / first listed register (257/258 = MSR/LSR). Encoding 

is per IEEE standard 754 single precision.

Units

Lists the physical units that a register holds.

Scale Factor   Some Integer values must be multiplied by a constant scale factor (typically a fraction), to be read correctly. This is done to allow 

integer numbers to represent fractional numbers.

Range

Defines the limit of the values that a register can contain.
