Interface Description 1 General 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.
1.2 RS232 Interface Connecting Cable Pin 2 3 5 Name RxD TxD GND Signal Receive data (T-Guard™ → PC) Transmit data (PC → T-Guard™) Reference Ground Interface Description The RS232 interface is wired as data communication equipment (DCE). T-Guard™ Leak Detection Sensor provides a 9-way sub-D socket for the connector. The signals are assigned as follows: The other pins are not being used.
2 RS232 ASCII Interface Protocol Interface Description The RS232 ASCII protocol is similar to the SCPI, a standard protocol widely used for measurement equipment. 2.1 Communication Parameters Data Format baudrate data bits parity stop bits flow control 2.2 19,200 or 9,600 8 none 1 none Command Format In ASCII mode any command starts with “ * “ (ASCII code 42 dec) and is finished with CR+LF. There is no differentiation between upper and lower case.

Profibus-DP Protocol 5.1 Preface Interface Description 5 In order to use Profibus-DP with T-Guard, you must have ordered a T-Guard in the Profibus version (Cat. No. 540-002). It is not possible to add the Profibus option to Cat. No. 540-001. When setting up the Profibus communication you need to use the GSD file provided by INFICON. 5.2 Process Data Mapping for Cyclic Data Transfer 5.2.

5.3 Acyclic Data Transfer Important Note: Interface Description If you want to use acyclic data transfer with Profibus, you must use a Profibus master which supports DPV1 data transfers. A Profibus master which supports DPV0 only, can only use cyclic data transfer. 5.3.1 Addressing Rules for Acyclic Access Fieldbus jins85e1 4.

Hardware Configuration Interface Description 5.4 Important Note: Sequence of the data words (slots) must be: Output at first, inputs at second. • One or two words are accessible at once. • Output and inputs must have the same memory start address. jins85e1 4.
Assignment of the Profibus Address Interface Description 5.4.1 The Profibus address has to be assigned with the hardware configuration tool. After downloading the configuration to the PLC system, the address of the T-Guard™ Profibus Client can be chosen like shown above. Diagnosis with the T-Guard™ Info Menu The current state of the T-Guard™ Profibus client is to be seen in the menu: (1101) 5.4.
