Device Presentation
The CPL165 is a complete and very compact measuring unit for power consumption measurement (building manage-
ment, workshops, data centers, ....) in an energy efficiency approach.
The Ethernet link allows measures supervision while ensuring easy and fast integration into existing networks. The inter-
nal bus allows multiple modules focused on Ethernet. The product can be used independently on a three-phase or a
single-phase network.
Devices have several options:
 CPL165 : low level Tio input.
 CPL165/CMTCP : Ethernet Modbus TCP link.
 CPL165/BUS : Slave version over internal bus (Modbus TCP).
 CPL165/SNMP : Ethernet link SNMP protocol (no internal bus).
 CPL165/CM : RS485 Modbus link (9600/19200 bauds).
No internal bus incorporated on DIN rail if RS485 modbus or SNMP.

1) Introduction
To meet its policy concerning EMC, based on the Community directives 2014/30/EU & 2014/35/EU, the
LOREME company takes into account the standards relative to this directives from the very start of the con-
ception of each product.
The set of tests performed on the devices, designed to work in an industrial environment, are made in accor-
dance with IEC 61000-6-4 and IEC 61000-6-2 standards in order to establish the EU declaration of confor-
mity. The devices being in certain typical configurations during the tests, it is impossible to guarantee the re-
sults in every possible configurations. To ensure optimum operation of each device, it would be judicious to
comply with several recommendations of use.
2) Recommendations of use
2.1 ) General remarks
- Comply with the recommendations of assembly indicated in the technical sheet (direction of assembly,
spacing between the devices, ...).
- Comply with the recommendations of use indicated in the technical sheet (temperature range, protection
index).
- Avoid dust and excessive humidity, corrosive gas, considerable sources of heat.
- Avoid disturbed environments and disruptive phenomena or elements.
- If possible, group together the instrumentation devices in a zone separated from the power and relay cir-
cuits.
- Avoid the direct proximity with considerable power distance switches, contactors, relays, thyristor power
groups, ...
- Do not get closer within fifty centimeters of a device with a transmitter (walkie-talkie) of a power of 5 W, be-
cause the latter can create a field with an intensity higher than 10 V/M for a distance fewer than 50 cm.
2.2 ) Power supply
- Comply with the features indicated in the technical sheet (power supply voltage, frequency, allowance of the
values, stability, variations ...).
- It is better that the power supply should come from a system with section switches equipped with fuses for
the instrumentation element and that the power supply line be the most direct possible from the section
switch.
- Avoid using this power supply for the control of relays, of contactors, of electrogates, ...
- If the switching of thyristor statical groups, of engines, of speed variator, ... causes strong interferences on
the power supply circuit, it would be necessary to put an insulation transformer especially intended for instru-
mentation linking the screen to earth.
- It is also important that the installation should have a good earth system and it is better that the voltage in
relation to the neutral should not exceed 1V, and the resistance be inferior to 6 ohms.
- If the installation is near high frequency generators or installations of arc welding, it is better to put suitable
section filters.
2.3 ) Inputs / Outputs
- In harsh conditions, it is advisable to use sheathed and twisted cables whose ground braid will be linked to
the earth at a single point.
- It is advisable to separate the input / output lines from the power supply lines in order to avoid the coupling
phenomena.
- It is also advisable to limit the lengths of data cables as much as possible.

BUS100 system
The BUS100 is a modular system composed of one master (/CMTCP module. Module with Ethernet link) and slaves
modules (/BUS model without Ethernet link). All modules are reachable by the Ethernet link. Each module is accessible
via its own address range. The master module is always accessible in the address range of 0 to 999. The slaves module
(/BUS module) are reachable in an address range equal to 1000 x BUS address. The address parameter is configur-
able by the front face of device and should be different for each BUS module connected as shown below.

The register addresses for the master module (address 0) range from 0 ($ 0000) to 134 ($ 0086).
A module with a bus address = 5, have measures registers reachable from 5000 ($1388 hexa) to 5134($140E)
1) Feature
Protocol: MODBUS TCP
Link: Ethernet 10/ 100 base T
IP address by default: 192.168.0.253
Port: 502
Connector: RJ45
Read request: Function code 03, 04
Write request: Function code 06, 16
Type of data: Inputs measurements.
data format: 16 bits and 32 bits unsigned integer.
2) Communication
Measures are refreshed every 2 seconds.
The CPL165 supports to be questioned by several Modbus TCP masters (maximum 6).
The response time to a request is about 20ms, it is strongly influenced according to the network traffic. Excessive load
can cause communication errors (response time of the slave exceeded (timeout), ....).
The response time for a write request is in the order of 0.6 s and up to 1.2 s. This is due to the mechanism for reading
BUS devices: The master continuously polls the present BUS modules. As the write request is inserted between two
readings, so you have more time to finish reading, proceed the writing, wait and return the BUS module acknowledg-
ment.
3) Data’s description
3.1) Available data's
All measures are reachable in reading mode. Data are available in different formats:
- 1 word or 2 bytes for voltage, current, phi cosines (power factor) measurements.
- 2 word or 4 bytes for power measurements and energy meters.
3.2) Data’s format
- The voltages are transmitted in 16 bits unsigned integer format corresponding to the measurement * 10.
- The currents are transmitted in 16 bits unsigned integer format corresponding to the measurement * 100.
- The phi cosines are transmitted in 16 bits unsigned integer format corresponding to the measurement * 100.
- The powers are transmitted in 32 bits unsigned integer format corresponding to the measurement in W * 100.
- The energies are transmitted in 32 bits unsigned integer format corresponding to the measurement in kWh * 100.
Data are transmitted Most Significant Byte first.
4) Reset of the energy meters
The reset of the energy meters is done by writing 1, 2 or 3 registers at address 300, 301 or 302.
The register at address 300 corresponds to phase 1, 301 to phase 2 and 302 to phase 3.
The value of the register corresponds to the different channels "A-F" to clear:
- Bit 0 (LSB) corresponds to channel A, bit 1 to channel B, up to bit 5 witch corresponds to channel F.
- To clear a counter, set the corresponding bit to 1.
Ex:
If you want to reset the counters W1A, W2B, W3C, so you writes 0001 at address 300, 0002 at 301, 0004 at 302.

5) Measures Tables
The tables show the addressing of the CPL165/CMTCP (bus address = 0). To know the address of the other modules
on the bus, it is necessary to add an offset corresponding to 1000 x the location of the module on the bus100.
(Ex: to read the value of current 2C for the bus module at address = 4, read the register located at address 4040
($0FC8).)

MODBUS communication
1) Feature
Protocol: MODBUS
Link: RS485
Connector: 4 pins connector
Read request: Function code 03, 04
Write request: Function code 06, 16
Type of data: Inputs measurements.
data format: 16 bits and 32 bits unsigned integer.
2) Communication
Measures are refreshed every 2 seconds.
The response time of the CPL165 to a read request is between 20 ms and 150 ms.
For a write request it is between 200 ms to 500 ms.
3) Data’s description
3.1) Available data's
All measures are reachable in reading mode. Data are available in different formats:
- 1 word or 2 bytes for voltage, current, phi cosines (power factor) measurements.
- 2 word or 4 bytes for power measurements and energy meters.
3.2) Data’s format
- The voltages are transmitted in 16 bits unsigned integer format corresponding to the measurement * 10.
- The currents are transmitted in 16 bits unsigned integer format corresponding to the measurement * 100.
- The phi cosines are transmitted in 16 bits unsigned integer format corresponding to the measurement * 100.
- The powers are transmitted in 32 bits unsigned integer format corresponding to the measurement in W * 100.
- The energies are transmitted in 32 bits unsigned integer format corresponding to the measurement in kWh * 100.
Data are transmitted Most Significant Byte first.
4) Measures tables
The registers are accessible in the address 0000 - 134. The arrangement of the measures is the same as for MODBUS
TCP (refer to the tables on pages 16 to 19).
5) Reset of the energy meters
The reset of the energy meters is done by writing 1, 2 or 3 registers at address 300, 301 or 302.
The register at address 300 corresponds to phase 1, 301 to phase 2 and 302 to phase 3.
The value of the register corresponds to the different channels "A-F" to clear:
- Bit 0 (LSB) corresponds to channel A, bit 1 to channel B, up to bit 5 witch corresponds to channel F.
- To clear a counter, set the corresponding bit to 1.
Ex:
If you want to reset the counters W1A, W2B, W3C, so you write 0001 at address 300, 0002 at 301, 0004 at 302.
6) RS485 bus wiring
The CPL165 have a 4-pin connector to facilitate the networking of the devices. A switch activates the terminating resis-
tor. (this resistance limits the reflections on the RS485 line. It should be only activated at each end of the bus).
Note:
The read request is limited. It is only possible to read a maximum of 125 consecutive registers.
