Configuring the data interface
Interface type
The ISD 260 and ISD 280 systems are equipped with one RS 422/485 interface per
unit which can be operated in 2 or 4-wire technology and in the Profibus (DP) and
Interbus-S.
Damage to the interface module!
The interface modules in the ISD 260/280 may be damaged if the DIL switching blocks
S 1 and S 2 are set incorrectly for the required configuration.
Ø
Configure the data interface correctly in accordance with
Fig. 5-11
