Hi,
We have a customer with a PLC Siemens S7-200, CPU224 and a card Ethernet CP243-1.
He use a Ewon Flexy201. (11.2s2)
He have read the documentation of your website about the communication between them with ISOTCP.

aug-017-0-en-s7-200_ppi_monomaster_remote_connection.pdf
The customer have had an error when he have configured the IOServer S7200 on Ewon.
Impossible to finished the configuration.
He have tried the IOServer S73&400 and this IOServer have worked with his PLC S7-200.
Why the IOServer S7200 did not work with his PLC S7-200 ?
It seems that the Ewon gives a error on the COM (serial COM ?).
The Flexy201 doesn’t have a serial COM.
The communication must to be on Ethernet LAN.
When he ‘apply’ on the IOServer S7200 page, Ewon gave this error :
The error : ERROR: Invalid COM port number specified
I send you pictures…
Thank you for your help,Flexy_S7200_ISOTCP_ERROR.pdf (325.7 KB)
