The company is based in Southern California and sells solid state relays and Ethernet-based input/output systems and controllers, it is based in California. Opto 22 was founded in 1974 as a manufacturer of solid state relays; the company soon expanded its offerings to include a variety of computer-based industrial automation, remote monitoring, data acquisition products. In 1978, Opto 22 developed the first computer-based plug-in I/O modules, created the Yellow-Black-White-Red color scheme used to identify digital AC input, digital AC output, digital DC input, digital DC output modules respectively. In 1982, the company created a serial-based I/O system using the ASCII protocol; the following year, with the introduction of the personal computer prompting a shift in the automation industry to PC-based control, Opto 22 developed what was to be the first in a series of software packages for designing control strategies on a PC using flowcharts.
This provided a new alternative to the more popular ladder logic programming model. Opto 22 introduced the mistic controller, which had many of the same features and functionality of a modern programmable logic controller. Opto 22 markets the SNAP brand of Ethernet products, including industrial processors, controllers, I/O racks and modules and accessories. In 2007 the company introduced the SNAP PAC System, adding higher powered controllers with redundant Ethernet communications, new programming and human machine interface development software, higher density I/O modules, database connectivity tools and software that simulated the SNAP PAC controller hardware; the result was a suite of control system components, suitable for simple cell control or complex, distributed control architectures.

RS-422 known as TIA/EIA-422, is a technical standard originated by the Electronic Industries Alliance that specifies electrical characteristics of a digital signaling circuit. Differential signaling can transmit data at rates as high as 10 Mbit/s, or may be sent on cables as long as 1,500 meters; some systems directly interconnect using RS-422 signals, or RS-422 converters may be used to extend the range of RS-232 connections. The standard only defines signal levels. RS-422 is the common short form title of American National Standards Institute standard ANSI/TIA/EIA-422-B Electrical Characteristics of Balanced Voltage Differential Interface Circuits and its international equivalent ITU-T Recommendation T-REC-V.11 known as X.27. These technical standards specify the electrical characteristics of the balanced voltage digital interface circuit. RS-422 provides for data transmission, using balanced, or differential, with unidirectional/non-reversible, terminated or non-terminated transmission lines, point to point, or multi-drop.
In contrast to EIA-485, RS-422/V.11 does not allow multiple drivers but only multiple receivers. Revision B, published in May 1994 was reaffirmed by the Telecommunications Industry Association in 2005. Several key advantages offered by this standard include the differential receiver, a differential driver and data rates as high as 10 Megabits per second at 12 meters. Since the signal quality degrades with cable length, the maximum data rate decreases as cable length increases. Figure A.1 in the annex plotting this stops at 10 Mbit/s. The maximum cable length is not specified in the standard. Limitations on line length and data rate varies with the parameters of the cable length and termination, as well as the individual installation. Figure A.1 shows a maximum length of 1200 meters, but this is with a termination and the annex discusses the fact that many applications can tolerate greater timing and amplitude distortion, that experience has shown that the cable length may be extended to several kilometers.
Conservative maximum data rates with 24AWG UTP cable are 10 Mbit/s at 12 m to 90 kbit/s at 1200 m as shown in the figure A.1. This figure is a conservative guide based on empirical data, not a limit imposed by the standard. RS-422 specifies the electrical characteristics of a single balanced signal; the standard was written to be referenced by other standards that specify the complete DTE/DCE interface for applications which require a balanced voltage circuit to transmit data. These other standards would define protocols, pin assignments and functions. Standards such as EIA-530 and EIA-449 use RS-422 electrical signals; some RS-422 devices have 4 screw terminals for pairs of wire, with one pair used for data in each direction. RS-422 cannot implement a true multi-point communications network such as with EIA-485 since there can be only one driver on each pair of wires; however one driver can fan-out to up to ten receivers. RS-422 can interoperate with interfaces designed to MIL-STD-188-114B. RS-422 uses a nominal 0 to 5 volt signal while MIL-STD-188-114B uses a signal symmetric about 0 V.
However the tolerance for common mode voltage in both specifications allows them to interoperate. Care must be taken with the termination network. EIA-423 is a similar specification for unbalanced signaling; when used in relation to communications wiring, RS-422 wiring refers to cable made of 2 sets of twisted pair with each pair being shielded, a ground wire. While a double pair cable may be practical for many RS-422 applications, the RS-422 specification only defines one signal path and does not assign any function to it. Any complete cable assembly with connectors should be labeled with the specification that defined the signal function and mechanical layout of the connector, such as RS-449; the most widespread use of RS-422 was on the early Macintosh computers. This was implemented in a multi-pin connector that had enough pins to support the majority of the common RS-232 pins; the ports could be put into either RS-232 or RS-422 mode, which changed the behavior of some of the pins while turning others on or off completely.
These connectors were used both to support RS-232 devices like modems, as well as AppleTalk networking, RS-422 printers, other peripherals. Two such ports were part of every Mac until they were replaced, along with ADB ports, by Universal Serial Bus on the iMac in 1998. RS-422 is a common transport mechanism for RS-232 extenders; these consist of RS-232 ports on either end of an RS-422 connection. Before hard disk based playout and editing systems were used, Broadcast automation systems and post-production linear editing facilities used RS-422A to remotely control the players/recorders located in the central apparatus room. In most cases the Sony 9-pin connection was used; this is the de facto industry standard connector for RS-422, still found on much broadcast equipment today.

Highway Addressable Remote Transducer Protocol
The HART Communication Protocol is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog only host systems. HART is used in process and instrumentation systems ranging from small automation applications up to the sophisticated industrial applications. According to Emerson, due to the huge installed base of 4–20 mA systems throughout the world, the HART Protocol is one of the most popular industrial protocols today. HART protocol has made a good transition protocol for users who wished to use the legacy 4–20 mA signals, but wanted to implement a "smart" protocol; the protocol was developed by Rosemount Inc. built off the Bell 202 early communications standard in the mid-1980s as a proprietary digital communication protocol for their smart field instruments. Soon it evolved into HART and in 1986 it was made an open protocol. Since the capabilities of the protocol have been enhanced by successive revisions to the specification.
There are two main operational modes of HART instruments: point-to-point mode, multi-drop mode. In point-to-point mode the digital signals are overlaid on the 4–20 mA loop current. Both the 4–20 mA current and the digital signal are valid signalling protocols between the controller and measuring instrument or final control element; the polling address of the instrument is set to "0". Only one instrument can be put on each instrument cable signal pair. One signal specified by the user, is specified to be the 4–20 mA signal. Other signals are sent digitally on top of the 4–20 mA signal. For example, pressure can be sent as 4–20 mA, representing a range of pressures, temperature can be sent digitally over the same wires. In point-to-point mode, the digital part of the HART protocol can be seen as a kind of digital current loop interface. In multi-drop mode the analog loop current is fixed at 4 mA and it is possible to have more than one instrument on a signal loop. HART revisions 3 through 5 allowed polling addresses of the instruments to be in the range 1–15.
HART revision 6 allowed addresses 1 to 63. Each instrument must have a unique address; the request HART packet has the following structure: Currently all the newer devices implement five byte preamble, since anything greater reduces the communication speed. However, masters are responsible for backwards support. Master communication to a new device starts with the maximum preamble length and is reduced once the preamble size for the current device is determined; this byte specifies the communication packet is starting. Specifies the destination address; the original addressing scheme used only four bits to specify the device address, which limited the number of devices to 16 including the master. The newer scheme utilizes 38 bits to specify the device address; this address is requested from the device using either Command 0, or Command 11. This is a one byte numerical value representing. Command 0 and Command 11 are used to request the device number. Specifies the number of communication data bytes to follow.
The status field is two bytes for the slave. This field is used by the slave to inform the master whether it completed the task and what its current health status is. Data contained in this field depends on the command to be executed. Checksum is composed of an XOR of all the bytes starting from the start byte and ending with the last byte of the data field, including those bytes; each manufacturer that participates in the HART convention is assigned an identification number. This number is communicated as part of the basic device identification command used when first connecting to a device. FieldComm Group. NET Open Source project
PROFIBUS is a standard for fieldbus communication in automation technology and was first promoted in 1989 by BMBF and used by Siemens. It should not be confused with the PROFINET standard for Industrial Ethernet. PROFIBUS is published as part of IEC 61158; the history of PROFIBUS goes back to a publicly promoted plan for an association which started in Germany in 1986 and for which 21 companies and institutes devised a master project plan called "fieldbus". The goal was to implement and spread the use of a bit-serial field bus based on the basic requirements of the field device interfaces. For this purpose, member companies agreed to support a common technical concept for production and process automation. First, the complex communication protocol Profibus FMS, tailored for demanding communication tasks, was specified. Subsequently, in 1993, the specification for the simpler and thus faster protocol PROFIBUS DP was completed. Profibus FMS is used for communication of data between Profibus Masters.
Profibus DP is a protocol made for communication between Profibus masters and their remote I/O slaves. There are two variations of PROFIBUS in use today; the many standard diagnostic options, in particular, are focused on here. PROFIBUS PA is used to monitor measuring equipment via a process control system in process automation applications; this variant is designed for use in explosion/hazardous areas. The Physical Layer conforms to IEC 61158-2, which allows power to be delivered over the bus to field instruments, while limiting current flows so that explosive conditions are not created if a malfunction occurs; the number of devices attached to a PA segment is limited by this feature. PA has a data transmission rate of 31.25 kbit/s. However, PA uses the same protocol as DP, can be linked to a DP network using a coupler device; the much faster DP acts as a backbone network for transmitting process signals to the controller. This means that DP and PA can work together in hybrid applications where process and factory automation networks operate side by side.
In excess of 30 million PROFIBUS nodes were installed by the end of 2009. 5 million of these are in the process industries. PROFIBUS Protocol To use these functions, various service levels of the DP protocol were defined: DP-V0 for cyclic exchange of data and diagnosis DP-V1 for acyclic data exchange and alarm handling DP-V2 for isochronous mode and data exchange broadcast The security layer FDL works with a hybrid access method that combines token passing with a master-slave method. In a PROFIBUS DP network, the controllers or process control systems are the masters and the sensors and actuators are the slaves; each byte is secured with an parity and transferred asynchronously with a start and stop bit. There may not be a pause between a stop bit and the following start bit when the bytes of a telegram are transmitted; the master signals the start of a new telegram with a SYN pause of at least 33 bits. Various telegram types are used, they can be differentiated by their start delimiter: SD1 = 0x10 SD2 = 0x68 SD3 = 0xA2 SD4 = 0xDC Three different methods are specified for the bit-transmission layer: With electrical transmission pursuant to EIA-485, twisted pair cables with impedances of 150 ohms are used in a bus topology.
Bit rates from 9.6 kbit/s to 12 Mbit/s can be used. The cable length between two repeaters is limited from 100 to 1200 m, depending on the bit rate used; this transmission method is used with PROFIBUS DP. With optical transmission via fiber optics, star-, bus- and ring-topologies are used; the distance between the repeaters can be up to 15 km. The ring topology can be executed redundantly. With MBP transmission technology and field bus power are fed through the same cable; the power can be reduced in such a way. The bus topology permits branching to field devices; the bit rate here is a fixed 31.25 kbit/s. This technology was specially established for use in process automation for PROFIBUS PA. For data transfer via sliding contacts for mobile devices or optical or radio data transmission in open spaces, products from various manufacturers can be obtained, however they do not conform to any standard. PROFIBUS DP uses two core screened cable with a violet sheath, runs at speeds between 9.6 kbit/s and 12 Mbit/s.
A particular speed can be chosen for a network to give enough time for communication with all the devices present in the network. If systems change then lower communication speed is suitable, if the systems change then effective communication will happen through faster speed; the RS485 balanced transmission used in PROFIBUS DP only allows 126 devices to be connected at once. PROFIBUS PA runs at fixed speed of 31.25 kbit/s via blue sheathed two core screened cable. The communication may be initiated to minimise the risk of explosion or for the systems that intrinsically need safe equipment; the message formats in PROFIBUS PA are identical to PROFIBUS DP.
