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,
pull

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 which is over 99, you must s
et it via web
console.

Hardware Installation Procedure
1. Connect the power adapter. Connect the 12-48 VDC power line or
DIN-rail power supply to the MGate 5111’s terminal block.
2. Use a PROFIBUS cable to connect the MGate to a PROFIBUS PLC or
other PROFIBUS master.
3. 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.
4. 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. The following figure illustrates the two mounting
options:

5. 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 mm2conductor 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.
ATTENTION
For installations in hazardous locations (Class 1, Division 2):
These devices are to be installed in an enclosure with a
tool-removable cover or door, suitable for the environment.
