5.4 Set instrument address

An address must be assigned to each Probus PA instrument. The

approved addresses are between 0 and 126. Each address must

only be assigned once in the Probus PA network. The sensor is only

recognized by the control system if the address is set correctly.

When the instrument is shipped, address 126 is adjusted. This ad-

dress can be used for function test of the instrument and for con-

nection to a Probus PA network. Then address must be changed to

integrate additional instruments.

The address setting is carried out either via:

•

The address selection switch in the electronics compartment of

the instrument (address setting via hardware)

•

The display and adjustment module (address setting via software)

•

PACTware/DTM (address setting via software)

The hardware addressing is eective if an address <126 is adjusted

with the address selection switches on the instrument. Hence the

software addressing is no longer eective, the adjusted hardware

address is valid.
