T510 MODbus -> PA - Fieldbus International AS

General description:

The T510 is DIN rail module for interfacing Modbus instruments to a PROFIbus PA network.

The T510 is a complete transmitter module. It allows interfacing of up to 4 Modbus instruments. The dynamic variables can either be presented in the standard PROFIbus PA 3.0 format or as a block of data. The data length, the Modbus addresses and the Modbus data-rate are configurable using DPV1 services or through a Hyperterminal window on a PC. The module supports both a standard 3.0 profile Ident No as well as a Manufacturer specific Ident No.

T510 includes a Modbus master in order to communicate with a Modbus instrument. The module reads the variables from the instrument and converts this to a dynamic variable on PROFIbus. Four AI Function Blocks are supported. The location of the Modbus registers and data type of the Modbus variable can be configured.

The Primary Variable (PV) will be continuously read and updated. Any Modbus communication problem will be reported in the PROFIbus Diagnostics message.

The physical interfaces is RS 485.

The T510 supports alarm flagging in the module. The user can configure four alarm levels using a standard configuration tool.

The T510 supports low-pass filtering in the module. The user can configure the damping value using a standard configuration tool.

A transparent Modbus channel is available.

Configurations can be selected to allow for 2, 4, 8, 16 or32 bytes to be cyclically read and/or written to the device per Modbus instrument.

Applications

The T510 is intended for integration of existing Modbus instruments into PROFIbus PA network. It is intended for system integrators that are building PROFIbus PA based systems, and manufacturers of measuremt devices who want to offer PROFIbus PA capabilities in their Modbus instruments.
