This diagram shows a SNAP PAC S-series controller
connected to multiple Opto 22 serial-based I/O units over
an RS-485 serial network. The controller is also connected to
a larger, separate enterprise Ethernet network to provide
process data to a PC running Opto 22’s PAC Display HMI
software.
SNAP-PAC-S1 Controller and Serial-based I/O Units
The network shown in this diagram requires PAC Control Professional and PAC Display Professional.

I/O units are connected via a 2-wire RS-485 serial network
and are controlled by the SNAP PAC S-series controller. Each I/O
unit is connected to its own group of sensors and actuators.

Control Professional
The diagram also shows a PC running PAC Control
Professional; the control program (or strategy) that runs on
the SNAP controller was developed in this application. Once
developed, the strategy is downloaded to the controller and
runs independently.
