Syntax to use ISOTCP

ISOTCP,IP address,CalledTSAP

IP address : IP address of the PLC (ex:

10.0.120.204)

Called TSAP (*) : Transport Service Access Point

For the S7-200 family, you can use the Called TSAP

4D.57 which is the default TSAP for Step7

Micro/WIN connection.

Example:

Reach by ISOTCP the PLC at IP 10.0.120.204 with

the TSAP 4D.57

Table - ISOTCP device address syntax

(*) for Called TSAP:

● If you do not use the default TSAP 4D.57 and specify your own connection in the S7-200, be

sure to:

- use the same TSAP for the Server and the Client (ex: Local TSAP:12.00, Remote

TSAP:12.00)

- Check the "Enable the Keep Alive function for this connection" feature for this connection

otherwise the eWON will not be able to poll the device after a connection lost due to the

eWON reboot.

8. Save your settings by clicking on Update Config.
