Device Replacement Without Programming Device; Media Redundancy - Siemens SIMATIC ET 200eco PN M12-L System Manual

8.3.8

Device replacement without programming device

Requirement
A topology must be created in the project.
Device replacement without programming device
IO devices with this function can be easily replaced:
• The device name does not have to be assigned with the programming device.
The replaced IO device receives the device name from the IO controller, no longer from the
programming device. For this purpose, the IO controller uses the configured topology and the
neighborhood relationships determined by the IO devices. The configured setpoint topology
must agree with the actual topology.
If an I/O device was already in operation, reset it to factory settings before further use.

8.3.9

Media redundancy

Media redundancy
Function for ensuring the network and system availability. Redundant transmission links (ring
topology) ensure that an alternative communication path is made available if a transmission
link fails (STEP 7 V5.5 and higher).
