MGate 5105-MB-EIP Series User Manual

Parameter
Value
Notes
Connection type Point to Point, Multicast
When using a Multicast connection, Target (i.e.,
EtherNet/IP Adapter) must reply to the Multicast IP
address for the MGate to listen.
Timeout multiplier
x4, x8, x16, x32, x64, x128,
x512
Timeout value = packet rate x timeout multiplier (e.g., For
packet rate = 100 ms and timeout multiplier = 16, the
connection timeout = 1,600 ms).
Instance 1 to 2147483647
When the MGate is set as Scanner Mode, the user can set
the device’s Configuration Instance. An EIP adapter device
needs to set this value. If the Configuration Instance
setting is wrong, it will respond “invalid connection path.”
Modbus RTU/ASCII Settings
According to the Modbus RTU/ASCII settings, the MGate 5105-MB-EIP will act as a Modbus client/master or
Modbus server/slave to communicate with your Modbus RTU/ASCII devices. For slave mode, the MGate acts
as a server/slave and waits for the incoming connection from the Modbus client/master. In this mode, you
only need to specify the slave ID for the MGate gateway. For master mode, the MGate works as a
client/master and will try to send Modbus commands to the Modbus server/slave devices, so you will need
to specify the server/slave device IDs and the relative Modbus commands.
Slave Mode Settings
You will need to specify which Modbus protocols will run in slave mode. The MGate 5105-MB-EIP supports
Modbus RTU and Modbus ASCII protocols in slave mode.
