VFD-MS300/MH300 EtherNet/IP Communication Card CMM-EIP01
CMM-EIP01 Operation Manual
38
Basic configuration settings include device name, network settings, and timer settings.
1. Device name:
There may be several CMM-EIP01 devices present on the network. To select the
correct equipment, you can assign a name to each device. The devices will then
be correctly identified during search.
2. Network Setup:
(1) IP configuration:
There are 2 types of IP configurations: Static IP and DHCP.
Static IP address: Preset or manually modified by the user.
Dynamic IP address (DHCP): Automatically assigned by the DHCP server.
Option Description
Static The user manually enters the IP address, netmask, and gateway.
DHCP The polled DHCP provides the IP address, netmask, and gateway.
(2) IP address:
IP address is the location of a device on the network. Each device connected
to the network must be assigned an IP address. An incorrectly assigned IP
address will result in a device's connection failure. It may also cause other
equipment to disconnect from the network. Consult a network administrator on
how to set up the IP address. The default IP address of CMM-EIP01 is
192.168.1.5.
(3) Netmask:
Netmask: Netmask is an important parameter for setting up the subnet. It is
used to determine whether the IP address of a target device is located in the
same subnet as the local equipment. If it is not in the same network, the
device will send its packets to the gateway, and the gateway will send these
packets to another subnet. Incorrect settings may cause the target device to
be unable to communicate with the CMM-EIP01 properly. To see if your
settings are correct, conduct a bitwise AND operation between your IP
address and the netmask, and another bitwise AND operation between the IP
address of the target device and the netmask. If these two values are the
same, both IPs are in the same subnet. CMM-EIP01's default netmask is
255.255.255.0.
(4) Default gateway:
The gateway is the window of communication between two different subnets; it
allows devices on two different subnets to communicate with each other. For
example, if a LAN needs to be connected to the WAN, a gateway is necessary
to bridge the two communication networks. The IP of the gateway has to be in
the same subnet as the CMM-EIP01. The default gateway of CMM-EIP01 is
192.168.1.1.
3. Timer Settings:
This sets up the network keep-alive time (unit: seconds; range: 10 – 65,535;
default value is 30 seconds). If the connection idle time exceeds the keep-alive
time, CMM-EIP01 will disconnect the idle connection.
4. Exception settings: (detecting disconnection)
If the communication card detects that the network is disconnected, it can ask the
VFD to stop (in accordance with the drive's settings) or ignore the error to
maintain the current status (this function is supported by CMM-EIP01 version
1.04 and later).
