CHAPTER 1: INTRODUCTION Understanding Communication with the I/O Unit Choosing Communication Methods The following table can help you choose communication methods for the tasks you need to do. This task Can be done using these methods Details and references for information Configure I/O units. ioManager (I/O points and other functions) Monitor and control processes. Send email to or page someone. Send SNMP trap. Monitor devices through an enterprise management system. Give technicians an Opto 22 HMI with alarming and trending. Monitor and control Ethernet-based I/O units on the network. Share strategy variable data with Opto 22 controllers and other SNAP Ultimate I/O units (peer-to-peer communication). Communicate with Modbus/TCP hardware or software. Exchange I/O point data with third-party software such as HMIs. Recommended Alternate ioControl flowchart logic ioManager (for configuration), ioControl ioDisplay (purchase separately) ioControl (SNAP Ultimate, Ethernet, or Simple I/O) or OptoControl (SNAP Ethernet I/O only) ioControl (writes to memory map Scratch Pad areas) ioControl (I/O points only) or SNAP Ethernet I/O Driver Toolkit or IEEE 1394-based protocol ioManager Inspect window or SNAP Ethernet I/O Driver Toolkit or IEEE 1394-based protocol SNAP Ethernet I/O Driver Toolkit or IEEE 1394-based protocol Memory map Scratch Pad areas 8 SNAP Ethernet-Based I/O Units Protocols and Programming Guide If you are using ioControl, configure the system using ioManager. See the ioManager User’s Guide. For the Driver Toolkit, see Chapter 3. For the IEEE 1394-based protocol, see Chapter 4. See ioControl 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 ioControl logic, because both write to the brain’s memory map. For the Driver Toolkit, see Chapter 3. For the IEEE 1394-based protocol, see Chapter 4. If you are using ioControl, configure email using ioManager. See the ioManager User’s Guide. For the Driver Toolkit, see Chapter 3. For the IEEE 1394-based protocol, see Chapter 4. See ioDisplay User’s Guide. ioControl with a SNAP Ultimate I/O unit or SNAP-LCE controller (see ioControl User’s Guide & Command Reference) OptoControl with a SNAP-LCM4 controller and Ethernet adapter card (see OptoControl User’s Guide & Command Reference) ioControl does not write directly to peers, but places data in the memory map so peers can retrieve it by reading memory map addresses. See ioControl User’s Guide & Command Reference. Also see Appendix A, “SNAP Ethernet-Based Brain Memory Map.” Modbus/TCP See the Modbus appendix in the SNAP Ethernet-based I/O Units User’s Guide and Chapter 5 in this guide. OptoOPCServer and brain’s memory map Purchase OptoOPCServer separately. See OptoOPCServer User’s Guide and Appendix A, “SNAP Ethernet-Based Brain Memory Map.”

Write your own software application to communicate with the system. FTP and brain’s file system (SNAP Ultimate I/O only) C++ or Active X: SNAP Ethernet I/O Driver Toolkit and brain’s memory map. OptoOPCServer and memory map Scratch Pad areas (SNAP Ultimate and SNAP Ethernet I/O only) Opto 22’s IEEE 1394-based protocol and brain’s memory map. Purchase OptoOPCServer separately. See ioControl User’s Guide, OptoOPCServer User’s Guide and Appendix A, “SNAP Ethernet-Based Brain Memory Map.” For the Driver Toolkit, see Chapter 3. For the IEEE 1394-based protocol, see Chapter 4. Also see Appendix A, “SNAP Ethernet-Based Brain Memory Map.” Accessing SNAP Ethernet-Based I/O Units Over the Internet Since SNAP Ethernet-based I/O units are just like any other hardware on the Ethernet network, you can access them over the Internet in exactly the same way you would access a computer. The details depend on your network and Internet connection. Consult your system or network administrator or your Internet Service Provider (ISP) for more information. Special Notes for SNAP Ultimate I/O Units SNAP Ultimate I/O system architecture is explained in Chapter 2 of the SNAP Ethernet-based I/O Units User’s Guide. (If you haven’t already read this chapter, it’s a good idea to do so now before continuing.) As the chapter explains, the SNAP Ultimate brain handles input/output processing and flowchart-based control on two “sides” of the brain, as illustrated below: Rack Recommended Alternate Brain I/O modules The rack is shown with the SNAP Ultimate brain on the left, and the input/output modules on the right. The modules on the rack connect with devices in the real world, such as the light bulb, to monitor or control them. The combination of rack, brain, and modules shown in the illustration is referred to as an I/O unit. SNAP Ethernet-Based I/O Units Protocols and Programming Guide 9
