7. See the Appendix ( page 65 ) for information on power supplies and wiring.
8. Before turning on power to the controller, follow steps in the PAC Manager User’s Guide (form 1704) to
assign the controller an IP address to the controller (required for both standard and Wired+Wireless
models).
WHAT’S NEXT?
To start configuring controllers and I/O points, see “Configuring I/O,” below.
To learn more about SNAP PAC R-series controller capabilities and network options, see Chapter 3: System
Information.
To create PAC Control strategies to run on the controller, see the PAC Control User’s Guide (form 1700) and the
PAC Control Command Reference (form 1701). Both are available in PDF format and you can download them
free from our website, www.opto22.com .
To securely access data from I/O points and strategy variables in the PAC via its RESTful API (application
program interface based on the REST architecture), see
developer.opto22.com.
To work with the following items on the controller, see instructions in the PAC Manager User’s Guide :
• File system and FTP
• Security settings
• Port and interface configuration, including wireless communication for a Wired+Wireless model
To use OLE for process control (OPC) with SNAP PAC R-series controllers, purchase OptoOPCServer and see the
OptoOPCServer User’s Guide (form 1439, available with purchase of OptoOPCServer ).
To communicate with controllers using Modbus/TCP, see the Modbus/TCP Protocol Guide
(f
orm1678).
To communicate with an Allen-Bradley Logix PLC or other system using EtherNet/IP, see the EtherNet/IP for
SNAP PAC Protocol Guide (form 1770).
To program your own applications, see the OptoMMP Protocol Guide (form 1465).
Configuring I/O
No matter how you communicate with SNAP PAC R-series controllers, you will need to configure I/O points
and controller features.
If you are not using PAC Control (Opto 22’s flowchart-based control software), follow instructions in the
PAC Manager User’s Guide (form 1704).
If you are using PAC Control , I/O units and points must be configured to match the PAC Control strategy
you will run. You can configure most controller features and point functions either in PAC Control or in PAC
Manager.
In most cases, if you are already in PAC Control, configuration is easier there and you can use the loopback IP
address for SNAP PAC R-series controllers controlling themselves. However, some functions cannot be
configured in PAC Control.
If you use PAC Manager, you can save your configuration to a file, load it to multiple I/O units at once, and use
it for referencing points in OPC. You can also configure some controller features that are not available in PAC
Control. However, you cannot use the loopback address in PAC Manager.
