Hi, I have a 1212C PLC. The IP address configured is unknown and there is no technical details available with user. I tried using proneta and tried below with a test setup with spare Siemens PLC that I already had. 1. Configured PLC IP as 192.168.1.50 (assuming that this IP is not known to me) 2. Configured TIA Step 7 Prof station's IP as 10.9.9.168 (IP configured at PC) 3. Pinged at PLC IP from command prompt. No response received. used "arp -a" to detect list of connected Ethernet devices but the PLC IP not listed in response. The only time PLC IP was listed in arp-a command response when i configured additional IP to the network card of PC and the additional IP was 192.168.1.168 i.e. PLC & PC has the same IP layer/range. Alternate IP scanner software tools also detects PLC IP only when addition PC-IP is configured as described above. Please recommend solution to detect the IP configuration of an unknown PLC CPU. ------------------------------------------------------------------------------------------ |
