Hardware settings (DIP switches)

!
Note!
The simulation mode via the hardware setting has priority over the software setting.
You can make the following hardware settings for the FOUNDATION Fieldbus™ interface using
miniature switches (DIP switches) on the transmitter (→ å 9, Item no 4). There are eight DIP
switches. Only DIP switch 1 and 2 are in use.
• Switch 1: Simulation ON/OFF
With activated simulation, the sensor input transferred from the transducer block to the
function block can be set by the control system independent from the hardware input of an
input channel. For safety reasons, is strongly recommended to set the switch to OFF for
normal operation.
• Switch 2: Hardware write protection ON/OFF
Parameterization of the device via the bus is no longer possible when write protection is
activated (setting ON).

Commissioning

5.5.1 Identification, Device ID, PD Tag
In the case of the FOUNDATION Fieldbus™, the device is identified in the host or configuration
system by means of the device ID (DEVICE_ID). The DEVICE_ID is a combination of the
manufacturer ID, device type and device serial number. It is unique and can never be assigned
twice.
The DEVICE_ID of the device is composed as follows:
• DEVICE_ID = 452B4810CD-XXXXXXXXXXX
• 452B48 = Endress+Hauser
• 10CD = TMT125
• XXXXXXXXXXX = device serial number (11-digit)
The serial number is also provided on the name plate:
• On the upper right side of the DIN rail transmitter
• On the upper side of the field housing cover
The PD Tag contains as default a cleartext identification for the device and the serial number,
"EH_TMT125_ xxxxxxxxxxx".
