Chapter 5 – Programming5-2NIBA-01 Installation and Start-up GuideCOMM. MODE This parameter selects the operating mode of the NIBA-01. TheNIBA-01 InterBus-S Adapter Module has two operating modes.PCPProcess data channel and PCP channel enabled. This setting shouldbe selected if drive parameters are to be adjusted through the fieldbus.IOProcess data channel enabled only. This setting is ideal for applicationsthat do not require drive parameter adjustment through the fieldbus.Furthermore, equipment set-up is also simple, requiring only thedefinition of addressing areas by means of the controller program.IB TIME-OUT If the communication between the NIBA-01 and the host fails, thisparameter defines the time after which the NIBA-01 stopscommunicating with the drive. (See the drive manuals for informationon drive behaviour if this occurs.) Setting the parameter to 0 disablesthe function. Otherwise, 1 unit corresponds to approx. 0.1 seconds.Control Locations ABB drives can receive control information from multiple sourcesincluding digital inputs, analogue inputs, the drive control panel and acommunication module (e.g. NIBA-01). ABB drives allow the user toseparately determine the source for each type of control information(Start, Stop, Direction, Reference, Fault Reset, etc.). In order to givethe fieldbus master station the most complete control over the drive,the communication module must be selected as source for thisinformation. See the user documentation of the drive for information onthe selection parameters.
