This is chosen separate of the next from my network (192.168.1.x). Now i can reach from 192.168.1.x the logo8 but not the cmr module. If I change my pc to the logo network (192.168.20.x), I can reach the cmr module. Are there other people with the same issue ?

Thus are the IP addresses in the range of 192.0.0.0 to 223.255.255.255, the subnet mask is 255.255.255.0. The IP address consists of 4 segments, XXX.YYY.ZZZ.NNN. For all devices with which the logo is to communicate, must be in the same subnet, the first 3 segments (xxx.yyy.zzz) must be the same, only in the fourth segment, the device must be different. Example for my logo and my PC: PC = 192.168.178.NNN Logo = 192.168.178.030 Now I have changed to test the IP address to 192.168.078.030. The Logo software notes the transmission attempt that the logo is in a different subnet as the PC and proposes to create an additional, temporary Ip address for the PC. If you confirm the proposal with Yes, this temporary IP address is created for the PC and the Logo software can communicate with the logo and the program can be transferred. This is clearly the indication that the logo can not communicate with other devices, which are in a different subnet. Attachment Test.wmv (195 Downloads)
