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.
