3. SEL NET 2-Channel RS232C Unit (Model H-105)
The Super SEL Controller is equipped with a 1-channel RS232C port as a standard feature. This port is designed for commu-
nication with the Teaching Pendant or with a personal computer through our PC interface software. This port is not designed
for general communication purposes. The H-105 option was developed for users who intend to develop their own programs
and require communication with other devices via an RS232C port.
(1) What is SEL NET?
More and more manufacturers are turning to factory automation to improve manufacturing flexibility, increase efficiency
and streamline their manufacturing operations. Today's factories abound with PLCs, robot controllers, sensors and other
devices related to factory automation. These devices are typically connected by miles of cables and I/O wires. If all of these
factory automation systems could be combined via network, a control system with a high level of efficiency could be built.
Realizing this, the engineers at IAI developed what we call, SEL NET.
SEL NET Production Planning System
The following diagram shows a high-level main frame computer and several personal computers combined via a LAN. A
single PC is used to communicate with a Super SEL Controller via RS232C. In addition, several Super SELs are combined
via SEL NET and exchange synchronized or interlocked information among themselves. Although the main function of this
sample system is an exchange of control information, other information such as production planning information could be
shared.
