1.1 Serial RS232 and Field Bus Interfaces

This Interface Description explains how to configure, operate and control T-Guard™

Leak Detection Sensor via serial RS232 or field bus (e.g. Profibus).

For using the field bus module nothing has to be changed in the T-Guard menu.

Field Bus is only available with units already having a field bus interface module.

It is not possible to add field bus to a non-field-bus T-Guard unit.

Other field buses like BACnet MSTP, CANopen, CC-Link, ControlNet, CompoNet,

DeviceNet, Modbus-RTU, BACnet/IP, EtherCAT, EtherNet/IP, Modbus-TCP,

Profinet IO and SERCOS III are available on request.

When using the RS232 interface, you can choose between three protocols under:

Main Menu → Settings → Interfaces → RS232 Protocol

Choices are: ASCII, Binary and Printer Auto.

• The RS232 binary interface communication protocol is optimized for fast and

secure communication between T-Guard™ Leak Detection Sensor and a PC or

PLC.

• The RS232 ASCII interface communication protocol is easy to implement and

readable by human beings. It is possible to “talk” to T-Guard™ Leak Detection

Sensor with a terminal program like Hyperterm (refer to Chapter 3).

• The RS232 “Printer Auto” sends date, time, name of the parameter set, operation

mode, leak rate, trigger 1 and trigger 2, if enabled, after every measurement.

For example: 20.09.2009 09:20:09 14 LITERS ACCUMULATION 2.00E-

5 mbarl/ TRIG1: 3.00E-04
