Ip Filter; User Defined Format - Delta Electronics IFD9506 Operation Manual

Ethernet Communication Module IFD9506
Device address: Address of the slave PLC, which is different from that of Gateway
Relay IP address: IP address of the receiving terminal

5.6 IP Filter

The IP filter is used for restricting the connection of the network in case some uncertain IP will cause errors.
Only the IP set within a certain range can establish a connection. Other IPs will be rejected.
1. Enable IP filter function:
Check the box to enable IP filter.
2. IP address:
IP addresses that are allowed to establish connections. Max. 8 IPs are allowed.
3. Subnet mask:
Subnet mask of the IP that is allowed to establish a connection. To see whether the subnet mask is
allowed, conduct bitwise AND operation between the allowed IP and subnet mask and destination IP and
subnet mask. If the two values obtained are the same, the subnet mask is allowed by the network. For
example, assume the IP is 192.168.0.1 and subnet mask 255.255.255.255, the IP allowed to establish a
connection is 192.168.0.1 only. If the subnet mask is 255.255.255.0, the IPs allowed to establish
connections are 192.168.0.0 ~ 192.168.0.255.

5.7 User Defined Format

You can define your own format for the data to be transmitted. The items to be defined include the fixed length,
start item and stop item.
 Select RS-232 (User Define COM1) or RS-485 (User Define COM2) to connect the device.
 After clicking "Apply", switch to "User Define" page to set the "Fix Length", "Start Item" and "Stop Item" and
etc.
