7.3.1 IP settings

IP address, NetMask, Gateway, DHCP

The network parameters of the INSYS Ethernet can either be allocated, or received dy-

namically from a DHCP server in the network.

Please find a short introduction to this topic in Chapter 4.4.1.

Port

The set default port address indicates at which port the INSYS Ethernet waits for incom-

ing connections. If for outgoing connections no explicit port number is specified with the

ATD command, the default port setting will be used.

Default protocol

The set default protocol indicates with which protocol (TCP or UDP) the INSYS Internet

will wait for incoming connections. Connection requests from other protocol types will

be ignored. If no explicit protocol is specified for outgoing connections in the command

ATD, the default setting will be used.

Pertinent AT commands

AT#IP=<ip address>

Set IP address

AT#NM=<ip address>

Set NetMask

AT#GW=<ip address>

Set gateway address (must be in the same segment)

AT#PORT=<n>

Default port for incoming and outgoing connections

ATT

Default protocol for incoming and outgoing connections

ATU

Default protocol for incoming and outgoing connections

is UDP

AT#DHCP=<n>

Automatic parameter allocation via a DHCP server

7.3.2 Input transfer (I/O tunneling)

The function I/O tunneling allows for transmitting the signals from the INSYS Ethernet

transparently to the outputs of a second INSYS Ethernet.

It is necessary for the transmission that at the two involved devices the set combination

of destination address and destination port equal the according address and the port of

the remote terminal. At both devices, the transfer function must be activated.

The transmission of the inputs to the remote terminal takes place via UDP packets. The

UDP packets are automatically sent every 30 seconds, or within 1 second if changes occur

at the inputs. They include the status of the two alarm inputs UE and UE2. The remote

terminal processes the packets and sets its outputs UA and UA2 accordingly. It is thus

possible to transmit 2 I/O lines from one device to another one in a simple way.

The transmission of the IO signals via UDP takes place in the background and is inde-

pendent from a TCP data connection that may exist parallel.

Note

A UDP connection is not possible in connection with IO tunneling.
