2.3 IT Communication
2.3.1 Preliminary Remarks
In addition to S7 communication via Industrial Ethernet, the CP 243-1 IT also sup-
ports the services XPUT/XGET and READ/WRITE parallel to a variety of IT func-
tions. These include data communication via FTP, sending e-mails, and the capa-
bility of permitting up to four Web browsers to access data and status information
on the S7-200 system at the same time. See Fig. 2.
Sending an e-mail or active file access via FTP are initiated by the S7-200 user
program. Only one job at a time can be active for each of these two functions. Not
until the CP 243-1 IT has positively or negatively acknowledged the job can the
user program start another job.
