Modbus Plus to DH-485 Gateway

5301-MBP-DH485

Disponibilidad Limitada: Producto en stock limitado. More Info

The ProLinx Modbus Plus to DH-485 Gateway creates a powerful connection between devices on a Modbus Plus network and DH-485 devices. This stand-alone DIN-rail mounted protocol gateway provides one Modbus Plus DB9F port and one DH-485 configurable serial port.

The Modbus Plus protocol driver supports both Master and Slave implementations of the protocol on the DB9 Female Modbus Plus port. The Modbus Plus port is fully configurable.

The ProLinx DH485 protocol driver supports the Master and the Slave modes of the protocol, providing powerful data transfer capability with Rockwell Automation PLCs and HMIs. User configurable data mapping make the interface an easy to use and powerful data transfer tool.

Especificaciones

Internal Database

The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.

The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.

Application Data Area

The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.

Status Data Area

This area is used to store error codes, counters, and port status information for each port.

Configuration Data Area

This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.

Protocolos

MBP Protocol Specification


The Modbus Plus protocol driver supports both Master and Slave implementations of the protocol on the DB9 Female Modbus Plus port. The Modbus Plus port is fully configurable.


Protocol Specifications

The Modbus Plus protocol driver exists in dual Modbus Plus Ports (MBP). The driver can be configured on an individual port basis as either a master or a slave to interface with other Modbus Plus devices.

General Parameters

Modbus Function Codes

3: Read Multiple Data Registers (MSTR 2)
16: Write Multiple Data Register (MSTR 1)
Global data read (32 words per node max.)
Global data write (32 words per node max.)

Address Scope

1 to 64

Modbus Plus Functioning as a Master

Command List

Up to 200 commands on the master port, fully configurable for function, slave address, register to/from addressing and word count

Polling of command list

Configurable polling of command list, including continuous read or write commands and write on change of data (Function Code 16 Write command only)"

Modbus Plus Functioning as a Slave

Node address

1 to 64 (software selectable)


DH485 Protocol Specification


The ProLinx DH485 protocol driver supports the Master and the Slave modes of the protocol, providing powerful data transfer capability with Rockwell Automation PLCs and HMIs. User configurable data mapping make the interface an easy to use and powerful data transfer tool.


Protocol Specifications

The DH-485 protocol in its native form is a peer to peer token passing network. The ProLinx DH-485 driver accesses the network functioning either as a Master or as a Slave.

General Protocol Information

Error Checking

BCC and CRC

Communication Parameters

Local Station ID: 0 to 31
Port 0 Baud Rate: 110 to 38.4K baud
Port 1 Baud Rate: 110 to 19200 baud
Stop Bits: 1 or 2
Data Size: 7 or 8 bits
Parity: None, Even, Odd
RTS Timing delays: 0 to 65535 milliseconds

DH-485 Slave Mode

In Slave mode, the module accepts commands from one or more Masters to read/write data stored in the module's internal data memory. In this mode, the ProLinx unit is answering DH-485 commands and has the appearance of an SLC processor to the network.

DH-485 Master Mode

In Master mode, the ProLinx DH-485 driver will actively gather data from other devices on the network, controlling the read/write data transfer between the gateway and other DH-485 devices, such as SLC processors. Data transfer can be initiated and executed with the other devices without any ladder logic being required in the Rockwell Automation slave hardware.

DH485 Functioning as a Master

Command List

Up to 100 command per master port, each fully configurable for function, slave address, register to/from addressing and word/bit count

Polling of command list

User configurable polling of commands, including disabled, continuous and on change of data (write only)
