Operation
Before operating the TIC for the first time the valid and unique serial interface address
has to be set by means of the Profibus address selection switch. Alterations to the
address during operations are not permissible.
Illuminating Displays
This LED provides information on the general unit status and the communication with
the TIC unit. Upon switching on there is a test phase of approximately one second for
the LED. Only thereafter will the
Table 4.0.1 on page 8
be valid.
Please note
☞
In the case of the TCP 350 (TIC 253) the time which elapses between switching on the
instrument until the Profibus is available may amount to approximately
15 seconds!
