Choosing Communication Methods
How do you need to communicate with SNAP PAC R-series controllers to match the tasks your application
requires? Check the following table for help in choosing communication methods and finding out where to
look for more information on them.
This task
Can be done using these methods
Details and references for information
Recommended Alternate
Configure controllers.
PAC Manager (I/O
points and other
functions) or PAC
Control (I/O points
only)
For A-B systems,
use EtherNet/IP
Configurator.
OptoMMP Software
Development Kit or
IEEE 1394-based
protocol.
If you are using PAC Control, configure the system in PAC
Control configure mode. See the
PAC Control User’s
Guide
.
For A-B systems, see
EtherNet/IP for SNAP PAC Proto-
col Guide
.
For the Software Development Kit or IEEE 1394-based
protocol, see
OptoMMP Protocol Guide
.
Monitor and control processes.
PAC Control flow-
chart logic
PAC Manager
Inspect window or
OptoMMP Software
Development Kit or
IEEE 1394-based
protocol

PAC Control User’s Guide
&
Command Reference
.
CAUTION! Events and reactions set up using alternate
methods are faster than flowchart logic, but be careful if
you use them. They can conflict with PAC Control logic,
because both write to the controller’s memory map. For
Software Development Kit or IEEE 1394-based protocol,
see
OptoMMP Protocol Guide
.
Send email to or page someone.
Send SNMP trap.
Monitor devices through an
enterprise management system.
PAC Manager (for
configuration),
PAC Control
OptoMMP Software
Development Kit or
IEEE 1394-based
protocol If you are using PAC Control, configure email using PAC
Manager. See the
PAC Manager User’s Guide
.
For Software Development Kit or IEEE 1394-based proto-
col, see
OptoMMP Protocol Guide
.
Give technicians an Opto 22 HMI
with alarming and trending.
PAC Display See
PAC Display User’s Guide.
Give technicians a mobile opera-
tor interface for monitoring and
controlling systems/equipment
groov
See www.groov.com .
Monitor and control SNAP PAC
R-series controllers on the net-
work.
PAC Control
PAC Control with a SNAP PAC R-series or SNAP PAC
S-series controller (see
PAC Control User’s Guide
&
Command Reference
)
Share strategy variable data with
Opto 22 controllers and other
SNAP PAC R-series controllers
(peer-to-peer communication). PAC Control
(writes to memory
map Scratch Pad
areas)
Memory map
Scratch Pad areas
PAC Control does not write directly to peers, but places
data in the memory map so peers can retrieve it by read-
ing memory map addresses.
See
PAC Control User’s Guide
&
Command Reference
.
Also see controller’s memory map in
OptoMMP Protocol
Guide
.
Securely access I/O point and
variable data for use in data-
bases, other systems, or Inter-
net of Things (IoT) applications
PAC’s RESTful API
and HTTP/HTTPS
server
See the API and instructions at developer.opto22.com.
Communicate with Modbus/TCP
hardware or software.
Modbus/TCP See the
Modbus/TCP Protocol Guide (
form1678).
Communicate with Allen-Bradley
Logix PLC systems
EtherNet/IP
See the
EtherNet/IP for SNAP PAC Protocol Guide
(form 1770).
Exchange I/O point data with
third-party software such as
HMIs. OptoOPCServer
and controller’s
memory map Purchase OptoOPCServer separately. See
OptoOPC-
Server User’s Guide
and the memory map in
OptoMMP
Protocol Guide
.
Exchange PAC Control strategy
variable data with third-party soft-
ware such as HMIs.
FTP and control-
ler’s file system
OptoOPCServer
Purchase OptoOPCServer separately. See
PAC Control
User’s Guide
and
OptoOPCServer User’s Guide.
