WAGO I/O System 750

753-482 2AI 4-20mA 12 Bit S.E. HART

Manual

Version 1.2.0

Function Description

HART (Highway Addressable Remote Transducer) is an established variant of

digital field communication, which has been introduced as an industry standard

and which also enables multivariable field devices to be supported and used in

systems with conventional 4 mA to 20 mA technology. Typical applications are

transducers for the measurement of mechanical and electrical variables.

The HART protocol works using the FSK process (Frequency Shift Keying) in

accordance with the Bell 202 communications standard. Here, the digital signal,

which is made up of the two frequencies 1200 Hz (logic 1) and 2200 Hz (logic 0),

is sinusoidally superimposed on the analog current signal. By coding the digital

signal with zero mean value, additional information can be transmitted at the

same time without affecting the analog signal transmission. This information can

come from the field device and be intended for the process control system or for

maintenance (e.g., process variable, device status). However, information can

also be written to the field device – acyclically – for parameterization or

configuration.

Along with the simplex channel for the current signal (analog controller



field

device), the HART protocol therefore also provides a half-duplex channel for two-

way communication.

Further advantages of HART are simple construction, maintenance and

application as well as flexible data access via up to two operator control units (PC

and hand terminal). HART field devices and also HART masters are compatible

with 4-20 mA technology. HART field devices can therefore be used with non-

HART-compatible masters and vice-versa. This provides the great advantage

that the user can upgrade his system with HART modules step-by-step.

In the as-supplied state of the HART I/O module; i.e., in the default operating

mode, the HART device can be accessed directly from an IEC61131-3 program

via the I/O module. In this case, HART communication is achieved very easily by

means of the pre-prepared PLC library “WagoLibHART_0x.lib”, which is provided

by WAGO as a free download.

FDT tool routing to the DTM of the connected HART device is possible in default

operating mode for connecting the I/O module to various WAGO ETHERNET

controllers with the help of the 759-359 ModbusTCP/HART Gateway DTM.

With the simple parameterization of the HART I/O module via GSD (device

master data) or WAGO-I/O-

CHECK

, 4 operating modes can be selected specially

for using the HART I/O module in PROFIBUS systems, in which up to 4 HART

dynamic variables (PV, SV, TV, QV) can be incorporated in the cyclic process

image.

When using the PROFIBUS DP/V1 Coupler 750-333 or Controller 7509-833, FDT

tool routing to the DTM of the connected HART device is likewise possible in a

further operating mode in conjunction with the 759-360 PROFIBUS/HART

Gateway DTM.
