Basic Functions
Overview of Communications Functions
Overview of Communications Functions
FINS Communications Service
5. UDP (User Datagram Protocol)
6. TCP (Transmission Control Protocol)
7. FINS (Factory Interface Network Service)
8. FTP (File Transfer Protocol)
9. SMTP (Simple Mail Transfer Protocol)
10. POP3 (Post Office Protocol Ver. 3.0)
11. SNTP (Simple Network Time Protocol)
12. DNS (Domain Name System)
FINS commands can be sent to or received from other PLCs or computers on
the same Ethernet network by executing SEND(090), RECV(098), or
CMND(490) instructions in the ladder diagram program. This enables various
control operations such as the reading and writing of I/O memory between
PLCs, mode changes, and file memory operations.
Performs data communications. Data resends, priority control, flow control,
and other measures to ensure communications reliability are not per-
formed for UDP communications, so the transmitted data may not arrive at
the destination node. To increase reliability, it is necessary to program spe-
cial measures into the user applications.
Performs communications after establishing a connection (i.e., a virtual cir-
cuit) with the destination node, providing a highly reliable communications
service.
A protocol that sends messages between PLCs on any of various OMRON
FA networks. To ensure that transmitted messages arrive at the destination
node, it is necessary to program special measures such as retry process-
ing into the user's applications.
Transfers data files.
A communications protocol for sending e-mail by TCP/IP.
A communications protocol for receiving e-mail by TCP/IP.
A communications protocol for automatic clock adjustment by UDP/IP.
A communications protocol for determining IP address names according
to UDP/IP and TCP/IP.
