Hello edwin; Ethernet standards limit the length of a segment to 100m over copper wire (CAT 5, CAT 6...). To extend a segment (for another 100m) you can use a hub, preferably a switch. What you call remote IO, Siemens calls distributed I/O. Same concept. So, ET 200M stations can be setup on Profibus or Profinet as extensions of the central rack of the CPU with the I/O modules. Once they are configured in the CPU's hardware configuration, you read and write to them as if they were in the central rack. When you use Profinet or Profibus with another CPU, you can use the concept of i-device or i-slave (i- for "intelligent"). This means that you have to define the I/O areas in the device/slave that will be used exclusively for data exchanges with the IO controller/ master. The following application example should show you how the i-device concept is used in a Profinet connection between CPUs: https://support.industry.siemens.com/cs/ww/en/view/109478798 Hope this helps,

Hello edwin; What do you want to do exactly? You cannot us a CP 1243-7 LTE to connect to a distributed I/O station; it does not support Profibus or Profinet. You can use a CP 1243-7 LTE to exchange data with another CPU, using specialized functions. See the following application examples, they allow a CP 1243-7 LTE as one of the partners in the link. Links over TCP, UDP and ISO-over-TCP are discussed in the example.

no, in the case of wireless it doesn't use ET200M
