    E2s can communicate over both serial and Ethernet networks using Optomux, and simultaneously communicate using Modbus/TCP and the OptoMMP memory-mapped protocol over Ethernet. In addition, E1s and E2s can be used with Opto 22’s ioProject software suite. See form #1546, the E1 and E2 Data Sheet , for more information.

  • Page 7: Chapter 1: Introduction

    CHAPTER 1 Introduction About Optomux Optomux is a protocol used by a family of intelligent digital and analog I/O (input/output) units that operate as slave devices to a host computer. An Optomux I/O unit is a 4-, 8-, or 16-point assembly that accommodates optically-isolated analog or digital I/O modules.

  • Page 8: System Confi Guration

    CHAPTER 1: INTRODUCTION System Confi guration Physical Layout The high cost of electrical wiring and the noise susceptibility of analog signals make it desirable to place thecontrol or monitoring point as close to the controlled deviceas possible. Optomux offers design fl exibility, with as few as 4 points or as many as 4,096 points in one physical location.

  • Page 9: Wiring

    CHAPTER 1: INTRODUCTION Wiring Inputs and outputs are connected to the Optomux mounting rack via an industrial barrier strip with integral cable clamp for each terminal. Spade lugs, other wire terminations, bare wires, and tinned wires are all readily accepted. Serial link connections and power connections are also made via screw terminals. Data Transmission Optomux supports 8 baud rates (300, 600, 1,200, 2,400, 4,800, 9,600, 19.2K, and 38.4K) which are selectable via jumpers located on the Optomux unit.

  • Page 10: Features

    CHAPTER 1: INTRODUCTION Reading the values of 16 analog inputs on an analog Optomux unit requires a total of 79 command/response characters. The command sent by the host consists of 11 characters; the response from Optomux consists of 68 characters. If we assume a response time of 7 milliseconds, the following table shows system throughput based upon reading all 16 positions per transaction.

    CHAPTER 1: INTRODUCTION Time Delays Any or all output positions can function in time delay mode. Outputs can be set to operate with four types of delays. • Delay before turning OFF • Delay before turning ON • Pulse ON •...

  • Page 12: High/Low Value Recording

    CHAPTER 1: INTRODUCTION High/Low Value Recording The B2 can be instructed to remember the highest and lowest readings at input positions for recall by the host computer. Gain and Offset Calculation The B2 can be instructed to calculate and set offsets and gain coeffi cients for input positions allowing for easy calibration under software control.

  • Page 13: Chapter 2: Installation And Wiring

    CHAPTER 2 Installation and Wiring Physical Installation Mounting The B1 or B2 Optomux unit can be mounted in any attitude on any fl at surface. The mounting rack and removable brain board portion of the Optomux unit are supplied with permanently-attached standoffs. All of the standoffs should be secured for maximum phys i cal strength.

  • Page 14: Communications Wiring

    CHAPTER 2: INSTALLATION AND WIRING Communications Wiring A complete data link con nec tion at each Optomux unit (except the last in a string) consists of 10 wires: two twisted pairs (4 wires) and a common coming from the computer or pre vi ous Optomux unit, and two twisted pairs and a common going to the next Optomux unit.

  • Page 15: Unit To Unit

    CHAPTER 2: INSTALLATION AND WIRING Unit to Unit The fol low ing fi gure shows the con nec tion between adjacent Optomux units on the serial link. The Optomux unit at the end of the data link has only 5 wires — “To Host,” “From Host,” and common. HINT: Always think of the previous Optomux unit as the host.

    CHAPTER 2: INSTALLATION AND WIRING Installing Digital I/O Modules CAUTION: Be sure that all Optomux unit power and power to the controlled devices is removed before installing or removing I/O modules. Each position on a digital mount ing rack can accept either input or output modules.

    If an Opto 22 PBSA/B/C power supply is used with the digital racks, the + 5 VDC log ic connection is made by the supply when it is screwed to the rack. In this case, the only connection to be made is the 120 VAC (220 VAC or 10-28 VDC de pend ing on supply type) connection to the PBSA (PBSB or PBSC) supply.

  • Page 21: Brain Board Mount Ing

    CHAPTER 2: INSTALLATION AND WIRING Brain Board Mount ing The brain board mates with the header connector on the rack. The orientation of the digital brain board (B1) should be such that the brain board extends away from the rack. The ori en ta tion of the analog brain board (B2) is such that the brain board covers up the communications and power wiring on the an a log rack when it is plugged in.
