Communicating with the OIT system
The following sections point out the different ways to communicate with the OIT
system. Of note is the Easy Mode option, since this version requires the least prior
knowledge.
TCP/IP communication: This deals with a detailed communicating and
■
logging of the communication between the OIT system and a PLC.
Individual actions must be initiated separately see chapter 7.1.
TCP/IP communication as per RFC1006 standard: a protocol extension
■
for the TCP protocol see chapter 7.2.
TCP/IP communication with Easy Mode: the simplest connection
■
between a PLC and an OIT system. The connection is made through a
simplified set of instructions see chapter 7.3.
TCP/IP communication over a web browser (Diagnosis): Here a
■
connection to the internal OIT system web browser can be made on which
different information about the OIT system is located see chapter 7.4.
TCP/IP communication over FTP (diagnosis): a connection to the
■
internal FTP server of the OIT system can be made on which the fault
patterns are located see chapter 7.5.
7.1
TCP/IP communication:
The TCP/IP protocol enables communication between the PLC and OIT system.
Refer to the network configuration overview to view the configuration data (see
table "Network configuration overview OIT" on page 29). The individual telegrams
that are exchanged in this bidirectional communication are arranged as follows:
