Reset Button

Restore the MGate to factory default settings by using a pointed object (such as a straightened paper clip) to hold the reset button down until the Ready LED stops blinking (approximately five seconds).
Pull-Up, Pull-Down, and Terminator for RS-485 (Modbus)

On the MGate 5111’s left side panel, you will find DIP switches to adjust each serial port’s pull-up resistor, a pull-down resistor, and a terminator.

SW	MODBUS
	1	2	3
	Pull-up resistor	Pull-down resistor	Terminator
ON	1 KO	1 KO	1200
OFF	150 IM (default)	150 KO (default)	– (default)

Rotary Switch

Before communicating, you must assign a slave ID to the PROFIBUS slave, If you would like to assign an address between 0 to 99, you need to change the rotary switch to the desired address. If you would like to assign an address that is over 99, you must set it via the web console.

Hardware Installation Procedure

Connect the power adapter. Connect the 12-48 VDC power line or DIN-rail power supply to the MGate 5111’s terminal block. Make sure the adapter is connected to an earthed socket.

Use a PROFIBUS cable to connect the MGate to a PROFIBUS PLC or other PROFIBUS master.
Use an Ethernet cable to connect the MGate to the Modbus TCP client, Modbus TCP server device, PROFINET IO controller, or EtherNet/IP scanner device.

The MGate 5111 is designed to be attached to a DIN rail or mounted on a wall. For DIN-rail mounting, push down the spring and properly attach it to the DIN rail until it “snaps” into place. For wall mounting, install the wall-mount kit (optional) first and then screw the device onto the wall.

Wall or Cabinet Mounting
Two metal plates are provided for mounting the unit on a wall or inside a cabinet. Attach the plates to the unit’s rear panel with screws. With the plates attached, use screws to mount the unit on a wall. The heads of the screws should be 5 to 7 mm in diameter, the shafts should be 3 to 4 mm in diameter, and the length of the screws should be more than 10.5 mm.

For each screw, the head should be 6 mm or less in diameter, and the shaft should be 3.5 mm or less in diameter.
The following figure illustrates the two mounting options:

The conditions of safe use:
a. Ethernet Communications Devices are intended for mounting in a tool-accessible IP54 enclosure and use in an area of not more than pollution degree 2 as defined by IEC/EN 60664-1.
b. Conductors suitable for use in an ambient temperature greater than 86°C must be used for the power supply terminal.
c. A 4 mm² conductor must be used when a connection to the external grounding screw is utilized.
d. Provisions shall be made, either in the equipment or external to the equipment, to prevent the rated voltage from being exceeded by the transient disturbances of more than 140% of the peak-rated voltage.

When wiring the relay contact (R), digital input (DI), and power inputs (P1/P2), we suggest using AWG (American Wire Gauge) 16-24 as a cable and the corresponding pin-type cable terminals. The connector can withstand a maximum torque of 5 pound-inches. The wire temperature rating should be at least 105°C.
