S7-400 Dial Out

Would anyone have an Siemens Step7 routine to set up an alarm paging system? The S7-400 PLC with CP441-2 must dial a modem and send alarm
messages to an alphanumeric pager.

Hi All

It would be better to do this using industrial ethernet, preferrably the IT version as it has the capability to link the PL program to a mail server with out any extra software costs (obviously other than the PLC program itself)

The serial option is probably possible, I doubt it will be easy.
