13echochange
Echochange - Manual / echochange 13
Connection to the Ethernet network
The device has two RJ45 sockets for Ethernet connection.
Use of 1 x RJ45
If you are using echochange in a heterogeneous network (i.e. the Ethernet protocols are running on
one medium), you will only need one Ethernet connector.

14 echochange
14 Echochange - Manual / echochange
Use of 2 x RJ45
If you are using the echochange as a bridge between two separate networks (i.e. the protocols are
running on different media), you will need both Ethernet connectors.
Connect one end of a TP cable with the TP socket (RJ45 socket) on the front panel of the device.
Plug the other end into an Ethernet hub/switch connected to your network.
The LEDs Eth 1 and/or Eth 2 should blink now. If they don't, please check the network connection
and cabling.
Installation of the configuration software
Using the NetCon echo configuration software, you define the basic configuration of the device and
set the parameters for your connections. The defined parameter settings are either transferred
directly to the device or stored locally for later transmission. The configuration software allows you to
monitor and diagnose configured connections. To configure the device, you will need a PC on which
the NetCon echo configuration software is installed. PC and device have to be connected either
directly or indirectly (see chapter 2.5). To install the configuration software, do the following:
1. Insert the CD-ROM in your CD drive.
2. Select the “echochange” installation.
3. You will be automatically guided through the installation process.

15echochange
Echochange - Manual / echochange 15
Connection of PC and device
A connection between PC and device is required for:
• Online configuration
• Transfer of a parameter file from PC to device and vice versa
• Diagnostic and test functions
• Programming of the S5 / S7 via network
The connection between PC and device can be established indirectly via bus.
Basic configuration
The echo device is configured with the NetCon software.
Resetting the device to default settings

2.6 Constraints of Protocol Conversion
Protocol-specific conditions, such as physical memory, S7 SSLs, PLC diagnostics or PLC circuits,
place constraints on protocol conversion. These elements are not supported and, consequently,
errors cannot be evaluated. Therefore, visualizations that are based on these functions (WinCC with
internal driver) cannot be used.
If requests do not match on both sides, no request is made on the destination side and an error is
immediately returned to the requester. This is the case, for example, with byte requests via word
protocols. Word/byte data is not converted. Byte swapping is processed, however.
Rockwell CLX uses little-endian, S7/S5 and Modbus usually use big-endian.
The S7 element types of the request are not evaluated because standard systems always request
bytes. The setting of the allocation table is used here. The byte setting prevents any swapping from
taking place. Bit requests are not possible. Bits are not included in any of the settings. If the
destination does not reply to the request, the requester waits for the result. The requester must not
make any further requests until it has received the response. To cancel a request, the connection
has to be reset. Standard request systems such as the OPC server or Visu driver behave like this.
PLC requesters sometimes do not know this behavior. They must wait or the PLC program must be
capable of a timeout. S5 protocols are capable of requests of any length and requests with undefined
lengths. The requests with undefined lengths (joker length) are not supported. Requests can have a
maximum length of 750 bytes.
Many protocols recognize detailed data types, but standard systems do not use them (particularly
with S7 and OPC servers). Applications' requests with variable offsets and lengths are combined into
one long request by these systems. Multiple offsets in the allocation table cannot be used in that
case. If necessary, the requester needs to adjust the optimization. Rockwell CLX is capable of arrays
and structure arrays. Arrays can only be processed from the beginning. Structure arrays are not
supported. When browsing, arrays and structure arrays are not resolved. For arrays, the browse
window displays the array length. Browsing of large PLC symbol lists is slow. After a maximum of 10
seconds, a browse request is canceled. This happens, in particular, with slow or overloaded
connections. Usually this behavior is caused by the short CLX frame lengths. The ping time has a
greater effect than the actual line speed. CLX structures that are completely specified in Modbus
register lists, for example, are not able to adapt the data individually.
When the source permits longer requests than the destination, the requests are processed by the
destination one after the other. If this processing exceeds the target length in the destination, the
transmission is aborted with an error message. During the write operation, part of the data has
already been transferred to the destination, however. The possible error signaling varies from protocol
to protocol. If an error occurs, protocol errors are converted although detail information may be lost.
Examples: S5 only recognizes “Data block does not exist” and “Data block is too short”, while S7
recognizes a large number of error codes. Rockwell CLX returns a general protocol error for non-
existent symbols or deviating data types. If both protocol sides support multiple requests in one
frame, the multiple requests are not always used on the destination side.

I. Preamble
The object of the contract is the computer program (called “SOFTWARE PRODUCT” hereafter)
stored on the data medium. The LICENSER states that the state of technology makes it impossible
to make computer software so that it will work correctly in all applications and combinations. Thus
the object of the contract is only a piece of software which works correctly in the sense of the
program description and user’s guide. The SOFTWARE PRODUCT including all contents (e.g.,
figures, graphics, text and sample applications) is and will remain the property of the LICENSER and
is thus protected by copyright.
The LICENSER is willing to give user’s rights as defined in this contract in return for an appropriate
licensing fee.
This license contract is concluded between LICENSEE and the LICENSER by the acceptance of the
SOFTWARE PRODUCT by the LICENSEE.

LICENSEE
Natural or legal persons who purchase this license for the purpose of using the SOFTWARE
PRODUCT.
THIRD PARTIES
Other natural or legal persons.
III. Scope
1. The SOFTWARE PRODUCT is exclusively licensed for use by the LICENSEE. The LICENSEE
may sell the SOFTWARE PRODUCT to THIRD PARTIES under the condition that the THIRD
PARTY agrees to this software licensing contract. In this case, the software license contract is
invalid for the LICENSEE and the utilization rights to the SOFTWARE PRODUCT are cancelled for
him since these rights have been passed on to a THIRD PARTY who has now become the
LICENSEE him/herself.
2. The SOFTWARE PRODUCT may only be used on a single computer. The LICENSEE is obligated
to purchase a separate license for every computer on which the SOFTWARE PRODUCT is used.

20 NetCon – General
20 Echochange - Manual / NetCon – General
A different agreement between LICENSEE and LICENSER applies to the purchase of multiple and
network licenses.
3. The duplication of the SOFTWARE PRODUCT and all related documentations is forbidden except
for the creation of an archive copy for exclusive use by the LICENSEE.
If the LICENSEE’s original data medium becomes defective, it can be exchanged at the
LICENSER for a replacement data medium. The cost of the exchange will be carried by the
LICENSEE.
4. The SOFTWARE PRODUCT is delivered on data medium as a demo version with restricted
function scope.
The demo version may not be used for commercial purposes. After payment of the licensing fee for
the particular desired version, the LICENSEE will receive a code number from the LICENSER for
the release of the corresponding SOFTWARE PRODUCT.
5. If a new program version is given to the LICENSEE due to the purchase of an update or for any
other reason, the user’s rights for the earlier program versions become void. This means that you
may only work with the latest version.
6. The LICENSEE and THIRD PARTIES are forbidden to modify the SOFTWARE PRODUCT or
reverse engineer it (i.e., de-compile or disassemble it).
The LICENSEE is liable for all damages which occur because of the violation of these conditions.
IV. Limited Warranty
The data carriers on which the SOFTWARE PRODUCT was delivered are free from material and
manufacturer’s flaws during normal use during a period of time of 6 months starting on the delivery
date. The data carriers are free of viruses according to the LICENSER. If, however hidden viruses
have snuck in, the LICENSER will not be liable for any subsequent damages which may occur.
1. The preceding limited warranty does not cover data carriers which have been damaged by chance
or misuse or manipulation of unauthorized parties (people other than employees of the
LICENSER).
2. During the stated guarantee period, the LICENSER is obligated to replace a defective data carrier if
this was sent to the LICENSER with a copy of the invoice. Other claims, in particular damage
claims, will not be honored subject to para. 4 and Roman numeral V.
3. No further guarantee claims will be allowed. In particular, no guarantee claims will be accepted for
program content and its freedom from errors or suitability for certain purposes. The responsibility
for software and hardware selection, for installation, use, expected results and data protection and
data backup with backup copies is the exclusive business of the LICENSEE.
4. Exceptions to the preceding warranty restrictions are promised characteristics. These promises
must be in writing to be valid and accompanied by the signature of the authorized representative of
the LICENSER. The LICENSER is only liable for damage claims in accordance with Roman
numeral V.
V. RESTRICTION OF LIABILITY
1. The LICENSER is not liable for damages unless the damage is caused by intent or gross
negligence of the LICENSER.
2. Liability due to any characteristics which may have been promised by the LICENSER is not
affected by this. Liability for subsequent damages due to deficiencies which were not included in the
promises of the LICENSER are excluded.
3. No liability is assumed for calculable damages, in particular lost profit.
4. Any damage claims are limited to the amount of the damage whose possible occurrence the
LICENSER logically had to expect under the circumstances known at that time when the contract
was concluded. In any case, liability is limited to the amount of twice the purchase price that was
paid (license fee), regardless of whether claims pertaining to contract law, damage claims or other
liability claims are concerned.
VI. Validity and Conclusion
1. The license given to the LICENSEE is valid until it is terminated by the licensee or the
LICENSER.
2. The LICENSEE can terminate the license at all times by returning the SOFTWARE PRODUCT
including the archivation copy and all related documentation to the LICENSER.
