Especificações

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

DFNT Protocol Specification


The EtherNet/IP protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.


Protocol Specifications

The EtherNet/IP protocol is one of the primary connectivity tools to the different Rockwell Automation platforms. The Explicit Messaging aspect of the protocol (only) has been implemented in the ProLinx units to provide the data transfer link between the ProLinx units and the Rockwell Automation hardware.

General Protocol Information

Messaging

PCCC on CIP
Explicit Messaging supported

Miscellaneous

125 word read and write data lengths
Floating point data supported

EtherNet/IP Server Specifications

In Server mode, the module accepts commands from one or more clients to read/write data stored in the module's internal registers.

EtherNet/IP Server Specifications

Connections

Five independent TCP server sockets permit remote clients to interact with all data contained in the module.

Data File

Data Table File Start - Fixed at N10
Data Table File Size - 100 or 1000 words

CIP Services Supported

0x4C - CIP Data Table Read
0x4D - CIP Data Table Write

EtherNet/IP Client Specifications

In Client mode, the module controls the read/write data transfer between the gateway and other EtherNet/IP devices. Data transfer can be initiated and executed without any ladder programming being required in the Rockwell Automation hardware.

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.
