 SAFETY WARNING
During the installation or use of control systems, users of Trio products must ensure that there is no possibility of injury to any
person or damage to machinery.
Control systems, especially during installation, can malfunction or behave unexpectedly. Bearing this in mind, users must
ensure that even in the event of a malfunction or unexpected behaviour, the safety of an operator or programmer is never
compromised.

RJ45 ETHERNET CONNECTOR (TOP)
A standard Ethernet connector is provided for use as the primary programming interface.
The Trio programming software, Motion Perfect 4 and above, must be installed on a Windows based PC that
is tted with an Ethernet connection. The IP address is displayed on the MC4N display for a few seconds after
power-up or when an Ethernet cable is plugged in.
The Standard Ethernet connection may also be used for Ethernet-IP, Modbus and other factory communications.
ETHERCAT PORT
The MC4N acts as an EtherCAT master. EtherCAT drives and I/O devices are normally connected in a chain.
Ethernet standard pin assignment:

Symetric or cross-over cables can be used between EtherCAT devices. Minimum CAT 5 shielded SF/UTPcable is recommended.

SHIELDING THE FLEXIBLE AXIS PORT
Ensure that:
1. The shield screw is grounded as close to the MC4N as possible.
2. 0V connection is NOT used for terminating screens.
3. Pin 5 of Encoder/Stepper plug is connected to 0V on drive.
4. Encoder cable screen is clamped to 9 way D shell.
5. The MC4N 24V supply has common 0V with the drive(s).
 WHEN WIRING MC4N STEPPER OUTPUT TO A DIFFERENTIAL
INPUT STEPPER DRIVE, USE THE 0V AND SHIELD CONNECTIONS
SHOWN FOR THE ENCODER. THE STEPPER DRIVE MUST HAVE ITS
COMMON 0V CONNECTED TO THE MC4N.

AMPLIFIER ENABLE (WATCHDOG) RELAY OUTPUT
An internal relay may be used to enable external ampliers when the controller has
powered up correctly and the system and application software are ready. The amplier
enable is a single pole solid state relay with a normally open “contact”. The enable
relay contact will be open circuit if there is no power on the controller OR an axis
error exists OR the user program sets it open with the WDOG=OFF command.
 ETHERCAT DRIVES WILL BE ENABLED VIA THE ETHERCAT NETWORK SO THE
“AMPLIFIER ENABLE” CONNECTION IS NOT NORMALLY REQUIRED.
ALL NON ETHERCAT STEPPER AND SERVO AMPLIFIERS MUST BE INHIBITED
WHEN THE AMPLIFIER ENABLE OUTPUT IS OPEN CIRCUIT.
An additional safety relay may be required so as to meet machine safety approvals.

DISPLAY
The IP address and subnet mask of the MC4N is shown on the LCD display for a few seconds
after power-up. The factory default IP address is 192.168.0.250. This can be changed using
the IP_ADDRESS command via the Motion Perfect software tool.

5-WAY CANBUS CONNECTOR
This is a 5 way 3.5mm pitch connector. The connector is used both to provide the 24 Volt power to
the MC4N CAN circuit and provide connections for I/O expansion via Trio’s CAN I/O expanders. A
24V dc, Class 2 transformer or power source should be used.
This 24V input is internally isolated from the I/O 24V and main 24V power.
 THE CAN CONNECTOR MAY BE LEFT UNUSED. THE MC4N IS GROUNDED VIA THE METAL
CHASSIS. FIT A SHORT SHIELD CONNECTION BETWEEN THE CHASSIS EARTH SCREW AND
THE EARTHED METAL MOUNTING PANEL / PLATE.
SD CARD
The SD Card may be used for storing or transfering programs, recipes and data to and from the MC4N. The card must be FAT32
format and a maximum 16Gb size.
 SD CARDS MAY BE FAT16 FORMATTED WHEN PURCHACED. RE-FORMAT IN A PC TO FAT32 PRIOR TO USE.

NETWORK SETUP
Network connection
Set IP_ADDRESS in MC4N to an available unused address.
It MUST match the subnet in use. Set the PC to use
DHCP server.
Note: the MC4N always has a xed IP address.
Point-to-point or closed network
(No DHCP server)
The PC MUST be set to a xed IP_ADDRESS.
The rst 3 “octets” MUST be the same as the MC4N and
the last MUST be dierent, but not 000, 254 or 255.
Setting a xed IP address
In Windows 7. Open “Network and Sharing Centre” then change “Adapter
Settings”. Select the properties of the Local Area Network and the IPv4
properties. The IP Address is set to 192.168.0.100 with subnet mask set to
255.255.255.0. Assuming that the MC4N has IP_ADDRESS=192.168.0.250 or
similar.

CHASSIS MOUNTING DIMENSIONS (LOOKING FROM FRONT)
M4 screws should be used in 2 places to mount the MC4N to an unpainted metal
panel.
The best EMC performance is obtained when the MC4N is attached from the shield
screw (marked) using a at braided conductor with a cross section of 4mm x 1mm.
Do NOT use a circular section wire or run the braid to a central star point.
 ENSURE THAT THE VENTILATION SLOTS AT THE TOP AND BOTTOM OF THE
MC4N ARE KEPT CLEAR TO ENSURE A FREE FLOW OF AIR THROUGH THE
MODULE.
