S BJECT: EXTENSION OF HARDWARE STRUCTURES FOR PROGRAMMABLE CONTROLLERS AND USER INTERFACES
IN THE C-PRO 3 SERIES
In order to ensure supply continuity, starting from early 2022 the programmable controllers and user interfaces in the
c-pro 3 series will be released with equivalent hardware solutions. Simultaneously, the new UNI-PRO 3.20.0.0 version
www.evco.it/en/autenticazione will be published in the EVCO website to support the change in the hardware structure.
The new UNI-PRO version allows backward compatibility with the devices previously manufactured and/or delivered,
while binary projects or applications precompiled with UNI-PRO versions older than the 3.20.0.0 will need to be
recompiled if used with devices featuring the new hardware structure.
The devices requiring updating are identified in the product label with 2 letters inside the numerical code of the product.
Below the complete list of the device item codes presently involved in this activity:
EPN2L EPU2B EPU3BR EPK3B EPB9BRE EPJC900X
EPN2LR EPU2BR EPU3BXP EPK3BEV EPB9BVE EPJC900X VW
EPN2LXC EPU2BSR EPU3LEV EV EPK3BSR EPB9BXE EPJC910X VW

Power supply, RS-485 port with Modbus slave communication protocol and CAN port
Terminal Meaning
V≅ + power supply controller (12 VAC in c-pro 3 micro and in c-pro 3 micro+, 24 VAC / 20... 30 VDC in c-pro 3 kilo and in
c-pro 3 kilo+); if the controller is powered in alternating current, connect the phase
V≅ - power supply controller (12 VAC in c-pro 3 micro and in c-pro 3 micro+, 24 VAC / 20... 30 VDC in c-pro 3 kilo and in
c-pro 3 kilo+); if the controller is powered in alternating current, connect the neutral
A / + terminal 1 of the transceiver RS-485 port
B / - terminal 0 of the transceiver RS-485 port
CAN + signal + CAN port
CAN - signal - CAN port
The maximum length of the connecting cables is:
- 100 m (328 ft) for the power supply
- 1,000 m (3,280 ft) for the RS-485 port; also look at the Modbus specifications and implementation guides manual
(the document is available on the internet site www.modbus.org).
The maximum length of the connecting cables of the CAN port depends on the baud rate of the CANbus communication, as
follows:
- 1,000 m (3,280 ft) with baud rate 20,000 baud
- 500 m (1,640 ft) with baud rate 50,000 baud
- 250 m (820 ft) with baud rate 125,000 baud
- 50 m (164 ft) with baud rate 500,000 baud.
Protect the power supply with a fuse rated 2 A-T 250 V.
If the controller is powered in direct current, it will be necessary to respect the polarity of the power supply voltage.
In case of connection in a network:
- for the devices powered at 12 VAC, the power supply of the devices in the network must be galvanically isolated one another
- for the devices powered at 24 VAC, it is necessary the phase powering the device is the same powering the remaining
devices in the network
- for the devices powered at 20... 30 VDC, it is necessary to recpect the polarity ot the power supply voltage of all the devices in
the network.
Connect the RS-485 port using a twisted pair.

The following table shows the function codes supported by the controller.
Function
code Meaning
FC 01 read coils
FC 02 read discrete inputs
FC 03 read multiple registers
FC 04 read input registers
FC 05 write single coil

FC 08 diagnostic
FC 15 write multiple coils
FC 16 write multiple registers
FC 23 read write multiple registers
For the settings about the RS-485 port look at chapter 6 “CONFIGURATION”.
The maximum number of devices that can make a CAN network (32) depends on the bus load; the bus load depends on the baud rate
of the CANbus communication and on the kind of device in the network.
For example: a CAN network can be made of a programmable controller, of four I / O expansions and of four user interfaces
with baud rate 500,000 baud.
Connect the CAN port using a twisted pair.
For the settings about the CAN port look at chapter 6 “CONFIGURATION”.
Termination RS-485 port and termination CAN port
Micro-switch to:
- plug in the termination of the CAN port (120 Ω, 0,5 W); position micro-switch 2 on position ON to plug in the termination of the
CAN port (plug in the termination of the first and of the last element of the network).
- to plug in the termination of the RS-485 port with Modbus slave communication protocol (120 Ω, 0.25 W); position micro-
switch 1 on position ON to plug in the termination of the RS-485 port (plug in the termination of the first and of the last element
of the network).
