English | SNAP-PAC-S1 SNAP PAC S-series Programmable Automation Controller for Ethernet Networks |
  |
The SNAP-PAC-S1 programmable automation controller provides powerful, real-time control and communications to
meet your industrial control, monitoring, and data acquisition needs.
One of the four components of the SNAP PAC System, the SNAP-PAC-S1 is fully integrated with PAC Project software,
SNAP PAC brains, and SNAP I/O modules to form a complete control system. The SNAP PAC System includes digital and
analog control, serial string handling, PID loops, and enterprise connectivity.
The controller is compact and industrially hardened. It includes two independent Ethernet network interfaces with
separate IP addresses, which can be used to segment the control network from the company network or for redundant
Ethernet links. You can also set up a system with redundant controllers using two identical S-series controllers, the
SNAP PAC Redundancy Option Kit, and PAC Project Professional 9.0.
The SNAP-PAC-S1 also has three serial ports: an RS-232 port with full hardware handshaking, ideal for PPP
communication using a modem; another RS-232 port for connecting directly to serial devices; and an RS-485 port for
connecting to SNAP PAC Serial brains or to legacy mistic I/O units. (Note: If you are using the S1 with misticI/O units,
use the legacy versions of the PAC Control, PAC Display, and PAC Manager guides.)
If you need Factory Mutual approval, see the SNAP-PAC-S1-FM.
If you need a similar PAC that also communicates wirelessly, see the SNAP-PAC-S1-W.
