eNod4-T Ethernet
Digital Process Transmitter
For any data to exchange, the encapsulated data format is most significant bit (MSB) transmitted first.
Access to the object model of a device is controlled by one of two objects: the Connection Manager, and the
UnConnected Message Manager (UCMM). We have already stated that EtherNet / IP is a connection-based network
and that most CIP™ messages are accomplished through connections. CIP™ also allows multiple connections to coexist
in a device at any given time.
eNod4 allows up to 4 simultaneous EtherNet / IP connections (sum of explicit and implicit connections).
In addition, it is not possible on the same module to access to different device application-specific Class for multiple
explicit connections. For implicit connection, eNod4 accepts 1 exclusive owner and up to 2 listener only.
eNod4 supports only cyclic connection CIP™ trigger.
6.3. Network configuration
Every eNod4 is identified on the network by an IP address, a subnet mask and a default gateway address. Network
configuration can only be set using eNodView software at minimum version V.
IP address: the IP address is comprised of two parts: the network address or Net ID (first part), and the host address
or Host ID (last part). This last part refers to a specific machine on the given sub-network identified by the first part.
The numbers of bytes of the total four that belong to the network address depend on the Class definition (Class A, B,
or C) and this refers to the size of the network.
Class C subnets share the first 3 octets of an IP address, giving 254 possible IP addresses for eNod4 device. Recall that
the first 00H and last FFH IP addresses are always used as a network number and broadcast address respectively.
eNod4 default local IP* address is 192.168.0.100
*if IP static configuration set
Subnet mask: a Subnet Mask is used to subdivide the host portion of the IP address into two or more subnets. The
subnet mask will flag the bits of the IP address that belong to the network address, and the remaining bits correspond
to the host portion of the address.
