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.

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.

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:
