ETC2002 Network Communicator
A wireless network is used as a transparent media for delivering Modbus
RTU messages. To identify devices on the network, each slave node is
assigned a network ID that is identical to the device Modbus address. See
Configuring Wireless RF Connections
in Chapter 5 for information on
configuring the IP-Link module parameters in the ETC2002.
Internet Connections
Starting with V21.5.4, the ETC2002 provides connections to slave devices
that are linked to the Internet via the Modbus/TCP or DNP3/TCP protocol.
The device routing table is used for assigning the IP addresses to slave
devices. See
Routing Messages over Slave Networks
information on using the device routing table in the ETC2002.
To configure Internet connections for your devices:
1. In the device routing table, specify the IP addresses for Internet
devices connected to the ETC2002. See
in Chapter 5 for more information.
2. Enable the routing table in your ETC2002 via the ETC2002
Gateway Options Setup (see
Chapter 5).
Master Network Connections
Internet Connections
The ETC2002 provides a TCP server for master client connections on one of
the standard TCP ports: 502 (Modbus/TCP), 20000 (DNP3/TCP) or 5002
(SATEC ASCII/TCP). The TCP server supports eight simultaneous client
connections.
NOTE:
Starting with V21.5.4, the ETC2002 provides the permanent
Modbus/TCP server on port 502. Selecting the TCP service port in
the ETC2002 (see
additional server either on the DNP3/TCP port 20000, or on the
SATEC ASCII/TCP port 5002, allowing simultaneous connections on
both ports.
The TCP server can be accessed via a local Ethernet network or via a Dial-
up PPP Internet connection using an embedded 56K modem.
The ETC2002 Dial-up port is programmable either for dial-in connections
from a remote TCP client via Windows Dial-Up Networking services, or for
dial-out connections to a remote TCP server via a local Internet Service
Provider (ISP).
Ethernet Connections
To setup your Ethernet connections:
1. Define the network IP parameters via the ETC2002 Network
Setup. If you use the ETC2002 eXpertPower client connections
via the Ethernet network, define a non-zero default gateway
address, so the client connections will be directed to the Ethernet
network (see Note in “Dial-Out Connections” below).
2. Define the TCP service port number for your application protocol.
See
in Chapter 5 for information on programming
the TCP service port in your ETC2002.
Dial-In Connections
To set up your dial-in connections, define the IP parameters for the modem
interface: the IP address, subnet mask and default network gateway, and the
number of rings before answering an incoming call.
