1 OPTOMUX DRIVER DESCR IPTION

The Optomux Driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using
the Optomux Driver protocol.

The Optomux driver is a client only driver. This means that the driver can poll an Optomux protocol compliant
device but cannot emulate one.

The Optomux protocol provides a large command set. Many of the commands are used for OPTO22 device
configuration. This driver supports the full command set and thus the driver may be used to configure as well as to
poll OPTO22 devices.

1.1 Operating Methods

The Optomux driver provides three methods of operation. Users may use any combination of methods.

1.1. 1 Static Operation

The devices to be polled/commanded are configured using the FieldServer CSV file. If the hardware configuration
is fixed and known then this is a suitable method.

1.1. 2 Dynamic Ope ration

The commands set can be configured by changing the values in the FieldServer’s Data Arrays. This data driven
operating mode is suitable if the hardware configuration may change or if hardware settings may change
dynamically or to change some aspect of the hardware configuration without changing the CSV file and resetting
the FieldServer..

1.1. 3 Triggered Operation

This operating mode allows commands to be triggered by changing the value in the FieldServer’s Data Arrays. This
operating mode is useful if requiring an action triggered by a remote device.

1.2 Statistics and Command Reponses

All FieldServer drivers report communication statistics that allow the operation of the driver to be monitored.

In addition to the standard statistics, this driver exposes the communication statistics for each port by presenting
them in a user specified Data Array where they can be monitored by a remote device or HMI system.

The Optomux driver also exposes the response status to each poll and command (if required) by writing the
response statuses to a user specified Data Array. This useful feature allows remote devices to check whether a
command has been completed successfully.

3 HARDWARE CONNECTIONS

The FieldServer is connected to the OPTO22 device as shown below.

Configure the OPTO22 device according to manufacturer’s instructions.

3.1 Connection Notes

 B2 Communication connections are made to the rack (PB4AH, PA8AH, PB16AH), not to the brain board.
 COM points must not be connected to Earth Ground.
 Bridging 4-wire RS-422 to get 2-wire RS-485 may not work in certain applications, and in this case it is

recommended that a RS-232 to RS-422 converter is used in between the FieldServer and the OPTO 22 devices .

4 DATA ARRAY PARAMETERS

Data Arrays are “protocol neutral” data buffers for storage of data to be passed between protocols. It is necessary
to declare the data format of each of the Data Arrays to facilitate correct storage of the relevant data.

5 CO NFIGURING THE FI ELDSERVER AS AN OPTOMUX DRIVER CLIENT

For a detailed discussion on FieldServer configuration, please refer to the FieldServer Configuration Manual. The
information that follows describes how to expand upon the factory defaults provided in the configuration files
included with the FieldServer (See “.csv” files on the driver diskette).

This section documents and describes the parameters necessary for configuring the FieldServer to communicate
with an Optomux Device.

The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable
the FieldServer for Optomux Driver communications, the driver independent FieldServer buffers need to be

declared in the “Data Arrays” section, the destination device addresses need to be declared in the “Client Side
Nodes” section, and the data required from the servers needs to be mapped in the “Client Side Map Descriptors”

section. Details on how to do this can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value being the default.

Data_Array_Name

Name of Data Array where data is to be stored / retrieved
in the FieldServer.

The use of this array is dependent on the Optomux
command used in the Map Descriptor.
For example some commands use one data value for all
module positions to be affected by the command (Driver
will only use one Data Array element). Other commands
may use one data element per module position specified. In
this case the FieldServer may use up to 16 Data Array
elements.
