Dial-Out Setup for PPP-Client

FP Web-Server V2.11

 

 

During dial-up connection. Both stations (e.g. 168.128.36.53 and 168.128.36.54 without using the gateway) can communicate with the FP Web-Server during the Internet dialup connection. The other stations (e.g. 11.11.13.129 and 11.11.13.109) that use the gateway may get communication errors while Internet dialup is active. This is valid for all connection modes of TCP communication, e.g. http, email, port communication and configuration (Telnet, FTP).

Blocked emails

Some email ISPs, e.g. GMX, may block sending emails if the PLC sends too many emails or emails are sent in quick succession. No official documentation or explanation could be found at GMX. It can be assumed that GMX blocks sending 'swamp mail'.

Modem connection and setup

The FP Web-Server's dial-out (PPP-Client) function is set up for RTS/CTS handshake (pin 7 and 8 of the 9-pin connector). The following two paragraphs describe how to setup the modem to also support RTS/CTS handshake. Only if the connected modem cannot support RTS/CTS handshake should pin 7 be bridged to pin 8. However, this is not recommended and should only be used with a slow modem baud rate (max. 9600 or 19200 bps).

The FP Web-Server firmware is designed for a FP Modem-EU connected to its 9-pin port for Internet dialup. For this a 1:1 9-pin RS232C cable (standard computer to modem cable) can be used to connect the FP Modem-EU to the 9-pin connector of the FP Web-Server.

The FP Web-Server assumes the FP Modem-EU factory default settings. To make sure that the FP Modem-EU has factory settings, please use a terminal program on your computer and enter the command AT&F&W. Please also make sure that all DIP switches of the FP Modem-EU are set to the OFF position!

If a standard computer modem is to be used it can also be connected by a 1:1 9-pin RS232C cable (standard computer to modem cable) to the 9-pin connector of the FP Web-Server. Before the modem is connected to the FP Web-Server, please use a
