TSX ETY 110 Module : General points
Introduction The communication channel of the ETHERNET TSX ETY 110 module offers two connection types : z connection to an ETHWAY network with common word and X-WAY messaging facilities on an ETHWAY profile, z connection to a TCP/IP network with X-WAY UNI-TE and Modbus messaging facility on a TCP/IP profile,
Because it functions as an SNMP agent, the module can be supervised by one or two SNMP managers.
Architecture type This module can be used in three different situations: z in a closed proprietary ETHWAY architecture z z in a proprietary ETHWAY architecture connected to a TCP/IP network by an intermediate gateway in open TCP/IP architecture via direct connection to the network.
According to your choice of architecture, the recommended method of use is different. See
Example of proprietary architecture ETHWAY, p. 187
.
z z
Note: When the ETHERNET network load passes 30%, it is recommended that you use : the TCP/IP profile instead of the ETHWAY profile, switch type accessories, routers to reduce the load.

Characteristics
Messaging
Maximum capacity of the module
The TSX ETY 110 module supports: z maximum 32 parallel connections on TCP/IP, z but only one connection to a remote device.
The maximum frame size depends on the type of transaction : z
In synchronous messaging, the maximum frame size is 256 bytes.
z
In asynchronous messaging, the maximum frame size is 1 Kbyte.
The number of communication functions handled simultaneously depends on the type of profile: z z where a TCP/IP profile is used, maximum 16 simultaneous messages, where an ETHWAY profile is used, maximum 16 simultaneous messages.
The module provides the following capacities: z z z in the case of ETHWAY messaging : 130 messages per second, in the case of X-Way messaging on TCP/IP : 140 messages per second,
in the case Modbus messaging on TCP/IP : 100 messages per second.
z z
Note: A message can be: sending a communication function, the response to a communication function.
Common words A common word message is equivalent to 0.5 data messages.
Example of application dimensioning :
5 stations exchange common words every 100 ms and X-Way messaging on
TCP/IP.
The flow of common words received by each module is 50 messages per second of common words, around 25 messages per second on TCP/IP.
So the remaining maximum capacity on each module on TCP-IP is:
140 – 25 + 115 messages per second

Performances
Example The performances below are given for a communication between two PLCs equipped with TSX 57-30 processors.
The values are expressed in ms and represent an average period of time described in the table.
Opening time of a TCP/IP connection
Transaction time for a UNI-TE request of 128 bytes in 50 ms periodic mode (MAST task)
Transaction time for a UNI-TE request of 128 bytes in 4 ms cyclic mode
(MAST task)
Transfer time for common words (turnaround ) in 50 ms periodic mode
Module feed-through time
10 ms
150 ms
80 ms
250 ms
15 to 30 ms
The transaction time takes into account the time it takes to send a message and receive a reply.

Module TSX ETY 110 operating modes
Introduction
General chart
The following graph describes the TSX ETY 110 module’s operating modes.
Module stopped Module off
Power up
Operation
Module configured Function of communication
Module at self-test stage
Reset
Configuration Module not configured
Self-tests OK z z z
After power-up the module self-tests. During this stage the warning indicators flash.
The module does not operate with a default configuration. This has to be transmitted to it by the local PLC’s PL7 application.
The configuration values are given in the list of %KW language objects.
The network, station address is given by the code selectors on the front panel.
When the configuration is received, the module resets the current communication to zero before configuring itself (terminates current exchanges, shuts down TCP connections).

Common functions on the ETHWAY and TCP/IP profile
Duplicate MAC address
Managing IP parameters
Detecting a duplicate MAC address (defined by the code selector) between stations which have a Schneider MAC address is done when the device is switched on.
So that this detection is operational, the connection cable to the network must be plugged in before being switched on.
The RUN and ADR LEDs light up on the front panel of the module when a duplicate is detected.
In a closed architecture you may choose not to configure IP parameters and to keep the default values.
In an open TCP/IP architecture, the IP parameters (IP address, subnet mask, gateway address) must be configured.
The default value of the local IP address is derived from the MAC address (its uniqueness is not guaranteed in an open TCP/IP architecture). It is a class A IP address.
MAC Address
16# 00 80 F4 00 <network address> <station address>
Default IP address
16# 54 00 <network address> <station address>
The default value of the subnet mask is 0.0.0.0 (no subnet knowledge).
The default value of the default gateway is 0.0.0.0 (no IP gateway knowledge).
