● The ET200M, ET200iSP and the PA-Link have to be connected with unassigned bus
modules.
● RESERVE submodules have to be inserted in the free slots on the ET200iSP.
Note
You can freely combine components which support system modifications
during
operation with those that do not. Depending on your selected configuration, there may be
restrictions affecting the components on which you can make system modifications during
operation.
Permitted system modifications: Overview
During operation, you can make the following system modifications:
● Add modules or submodules with the modular DP slaves ET 200M or ET 200iS
● Use of previously unused channels in a module or submodule of the modular slaves ET
200M or ET 200iS
● Add DP slaves to an existing DP master system
● Add PA slaves (field devices) to an existing PA master system
● Add DP/PA couplers downstream of a PA link
● Add PA-Links (including PA master systems) to an existing DP master system
● Assign added modules to a process image partition
● Change parameter settings for I/O modules, for example selecting different interrupt limits
● Undo changes: Modules, submodules, DP slaves and PA slaves (field devices) you
added earlier can be removed again
