Modules in IO devices of the type ET 200SP HA

Principle
If you are planning plant changes in RUN using CiR, pay attention to the following
information even during the planning phase of the ET 200SP HA stations:
● Select permitted CiR configurations for integration of the IO devices in the PROFINET
subsystem.
● Insert a sufficient number of slot covers for additional I/O modules in the IO device.
Rules for plant changes in run
● You may only add I/O modules directly behind the last existing I/O module or remove
them starting at the end of the existing I/O modules. A gap is not permitted in either case.
● You need at least two downloads to the CPU to replace an I/O module with an I/O module
of a different type for a configuration that already exists in the CPU:
– 1st download: The CPU receives the configuration that no longer contains the I/O
– 2nd download process: The CPU receives the configuration with the newly added I/O

DP and PA Slaves

Principle
When you are planning systems during operation via CiR, you must observe the following
already at the planning stages:
● Provide a sufficient number of branch points for tap lines or disconnect points (tap lines
are not permitted for operation at a transmission rate of 12 Mbps).
● ET 200M stations and DP/PA links must be designed with an active backplane bus.
Always try to equip the station with the maximum number of bus modules, as you can not
insert or remove a bus module during runtime.
● You must design the ET200iSP completely with terminal modules. Then equip all the
terminal modules that are assigned to the reserve area with reserve modules.
● Terminate the PROFIBUS DP and PROFIBUS PA bus lines with active bus termination
elements at both ends to ensure proper bus termination also during system
reconfiguration.
● PROFIBUS PA bus systems should be equipped with components of the SpliTConnect
product family to avoid having to disconnect cables.
