4. Overview

COUNTIS E13 and E14 are active modular electrical energy meters for monitoring kWh. They are designed for single-

phase networks and enable direct connection up to 80A. They are equipped with a MODBUS communication bus.

4.1. Main functions

• Measurement and display:

- active and reactive energy (T1 and T2): Ea+/Ea-/Er+/Er-

- of active and reactive power: P1+/P1-/Q1+/Q1-

• Management of two tariffs: T1/T2

• Measurement of electrical parameters accessible via the communication

- Voltage P-N: V1

- Current: I1

- Active power: P1+/P1-

- Reactive power: Q1+/Q1-

- Apparent power: S1

- Power factor: PF1+/PF1-

- Total active energy: Ea+/Ea-

- Total positive reactive energy: Er+

- Positive active energy per tariff: Ea+

- Positive reactive energy per tariff: Er+

• MODBUS communication

• MID version (according to reference)

6. MODBUS communication

6.1. General Information

MODBUS®communication is performed via a RS485 serial port (2- or 3-wire) which enables products to be used

from a PC or an API.

Onastandardconguration,aRS485portcanbeusedtoconnect32productstoaPCoraPLCacross1200

meters.

6.2. Recommendations

It is necessary to use a shielded twisted pair (LIYCY type). In an environment where there is interference or large

network (in terms of length) we recommend the use of a shielded twisted pair (type LIYCY-CY).

A repeater should be used to connect additional products if the distance of 1200 m and/or maximum number of 32

products is exceeded.

A120-ohmresistormustbexedatbothendsofthelink.

6.3. Communication structure

The product communicates via a MODBUS®protocol, which involves a dialogue using a master-slave structure. The

mode of communication is the RTU (Remote Terminal Unit) mode using hexadecimal characters of at least 8 bits.

MODBUS®frame structure(master -> slave exchange):

Slave address Function code Address Number of words to read CRC 16

1 byte 1 byte 2 bytes 2 bytes 2 bytes

6.4. Communication table

The communication tables and associated explanations are

available on the COUNTIS E13/E14 documentation page online at

the following address:
