MSA FS-8700-67 Russelectric ATS and Switchgear Instruction Manual

1 Description

The Serial Russelectric Model 2000 driver allows the FieldServer to transfer data to and from devices over either RS-232 or RS-485 using RTU protocol. The Russelectric Model 2000 drivers implement a Model 2000 Client and a Model 2000 Server. The Client driver can read data from a remote Server and send write data commands. The Server driver emulates a Model 2000 device and responds to data read and write poll commands.

Messages

The client driver implements the following RTU message or command types:

• Read_Output_Table – Used to read the bit values of the discrete outputs on the Model 2000.
• Read_Registers – Used to read the integer values of the Model 2000’s internal registers.
• Force_Single_Output – Used to set or clear the bit value of a single discrete output on the Model 2000.
• Preset_Single_Register – Used to load an integer value into a specific single register of the Model 2000.

Addressing

Every Model 2000 has a unique address assigned to it. The client driver can send messages to a specific Model 2000 by using the unique address in the message or by using a special broadcast address of value 0. Only the following messages can be sent in broadcast by the client (other messages are read data types and would cause a communications collision when all Model 2000 devices respond):

• Force_Single_Output
• Preset_Single_Register

All Model 2000 devices must receive and process a broadcast message. No device may send a response message in reply. Subsequent data read commands by the client driver will update the data that was changed or loaded by a broadcast message.

2 Driver Scope of Supply

2.1 Supplied by MSA Safety

2.2 Provided by the Supplier of 3rd Party Equipment

The user has to provide a suitable cable with appropriate connectors that will connect the Model 2000 either directly to the FieldServer or to the RS-232 to RS-485 converter. When connecting to a converter, consult the converter’s documentation for pinouts.

3 Hardware Connections

The FieldServer is connected to the Model 2000 as shown below.
Configure the Model 2000 according to manufacturer’s instructions

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.

5.3 Client Side Map Descriptor Parameters

5.3.1 FieldServer Specific Map Descriptor Parameters

characters

be stored in the FieldServer.

| One of the Data Array names from

Section 4

Data_Array_Offset| Starting location in Data Array.| 0 to (Data_Array_Length -1) as

specified in Section 4

5.3.3 Timing Parameters

5.4 Map Descriptor Example

Map_Descriptor_Name| , Scan_Interval| , Data_Array_Name| , Data_Array_Offset| , Function| , Node_Name| , Data_Type| , Address| , Length
---|---|---|---|---|---|---|---|---
RUS_MBA1| , 3.0s| , RTU_Digital_Out| , 0| , Rdbc| , Node_1| , Flag| , 1| , 34

In the above example:

• Map_Descriptor_Name – This can be any name but each name must be unique. Name will appear in FieldServer Map Descriptor status information screens.
• Scan_Interval – Scan interval must be adapted for multiple Map Descriptor scans to prevent a situation where not all Map Descriptors can be executed in a certain time. Take remote device response time into consideration here.
• Data_Array_Name – The data array name must be one found under Data_Arrays. Data from the scan will be stored into the array at Data_Array_Offset.
• Data_Array_Offset – This value specifies the offset into the data array (RTU_Digital_Out) where the data fetched must be stored.
• Function – The function may be read for read commands and write for write type commands. Continuous operations are allowed.
• Node_Name – Node name must be one found under Nodes, Node_name. Data will be fetched from this node and port during a scan. Use Node_0 with id of 0 to execute a broadcast command.
• Data_Type – Use Register to access Model 2000 registers or Flag to access the output table.

6 Server Side Configuration

For detailed information on FieldServer configuration, 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” sample files provided with the FieldServer).
This section documents and describes the parameters necessary for configuring the FieldServer to communicate with a Russelectric Model 2000 Client.
The configuration file tells the FieldServer about its interfaces, and the routing of data required. In order to enable the FieldServer for Russelectric Model 2000 communications, the driver independent FieldServer buffers need to be declared in the “Data Arrays” section, the FieldServer virtual node(s) needs to be declared in the “Server Side Nodes” section, and the data to be provided to the clients needs to be mapped in the “Server Side Map Descriptors” section. Details on how to do this can be found below.
NOTE: In the tables below, * indicates an optional parameter with the bold legal value as default.
