OPTO 22 K (OPTOMUX) Communication Server

The Klinkmann Automation OPTO 22 K (OPTOMUX) Communication Server (OPTO22K) is a Microsoft Windows application program that acts as a communication protocol Server and allows other Windows application programs to access data from OPTO 22 OPTOMUX B1 and B2 Digital and Analog Brain Boards. The Server requires an OPTO 22 AC7A or equivalent RS-422/485 converter or adapter to communicate with the OPTOMUX I/O Bus.

Any Microsoft Windows program that is capable of acting as a DDE, FastDDE, SuiteLink or OPC Client may use the OPTO22K Server.

There are following OPTO22K Server versions available:

- OPTO22K DDE & Suite Link Server (32-bit), can be used on MS Windows NT, W2K, XP and 95 (98);
- OPTO22K OPC & DDE Server, can be used on MS Windows NT, W2K, XP and 95 (98).

FEATURES

The OPTO22K Server handles the data exchange between host computer and OPTO 22 OPTOMUX Brain Boards over the RS-422/485 communication link.

The Brain Board configuration is separated from topic configuration, so allowing independently execute Brain Board setup commands.

The OPC support for OPTO22K Server OPC & DDE version conforms to OPC Data Access Custom Interface Specification 2.04. The OPTO22K Server OPC & DDE version is tested for compliance and is compatible with OPC Foundation OPC Data Access Compliance Test Tool.

The OPTO22K Server DDE & Suite Link version supports the Wonderware Suite Link communication protocol.

The OPTO22K Server uses an item/point naming naming is based on OPTOMUX commands used to access Digital and Analog Brain Boards.

Supports the possibility to execute the appropriate Brain Board configuration command at run-time by using special items.

Supports the possibility to suspend the communication with any topic at run-time by using special SUSPEND item.

Minimizes system message traffic by dynamically calculating and optimizing poll lists for client-requested items/points.

Supports multiple topics for each Brain Board, allowing different data update rates.

Provides a communication status flag for each topic.

Supports standard DDE among multiple applications.

SPECIFICATIONS

Hardware: IBM or compatible 386/486/Pentium equipped with a minimum of 4 MB RAM (16 MB RAM for Windows NT). May require more memory to run other Windows programs simultaneously.

Software: Microsoft Windows 95 (98), Microsoft Windows NT 4.0, W2K and XP.

Computer Interface: RS-232 through OPTO 22 AC7A or equivalent RS-422/485 converter or directly RS-422/485 adapter card plugged into computer.

Maximum Connections: The Server can access up to 255 Brain Boards which may be any combination of Digital or Analog Brain Boards.

Devices Supported: OPTO 22 OPTOMUX B1 and B2 Digital and Analog Brain Boards.

Accessible Point Types: The item/point naming system used by OPTO22K Server is derived from available read and write commands supported by OPTOMUX protocol. The Server supports a fixed set of item names, each of them generally may be described as:

PnS

where

n - an I/O module position number and may be from 1 to 16;
P - optionally used position number prefix representing the type of command;
S - optionally used position number suffix representing possible modification of command.

The following groups of items/points are supported:

- Normal digital and analog I/O items: Digital Inputs and Outputs, Analog Inputs and Outputs, Temperature Inputs (Centigrade and Fahrenheit).

- Digital Inputs as Digital Latches: reading the current state of latche, setting the I/O point to latch on OFF-to-ON or ON-to-OFF transition, setting the I/O point to unlatched state.

- Digital Inputs as Event Counters: reading the current value of counter, starting/resuming the counting of OFF-to-ON transitions, stopping the counting of OFF-to-ON transitions, reseting (clearing) the counter value.

- Digital Inputs used in Digital Pulse Duration Measurement commands: any Digital Input position can function as a pulse duration timer.

- Digital Outputs used in Delay/Pulse commands: any Digital Output position can function in time delay mode and specific number of pulses with programmable period and continuous square waves also can be generated.

- Analog Input Averaging commands: any Analog Input position can be instructed to average the values of successive readings.

- Analog Input Range commands: any Analog Input position can be instructed to establish input ranges causing flags to be set when either high or low limits are exceeded and remember the highest and lowest readings at this position.

- Output Waveform Generation commands: square waves, triangle waves and ramps can be generated at any Analog Output position.

- Digital and Analog Set Watchdog Delay commands: to monitor activity on the serial communication link and to instruct the Digital or Analog Brain Board to take a predetermined action if there is no activity within a specified time.

- Special items to control the execution of OPTO22K Server in case power failure happens: transfer configuration commands to separate Brain Board and write back automatically or manually the last values of Digital or Analog Outputs.
