So I have finally had to bite the bullet and do some modifications to some Siemens PLC code written in TIA.
I have got both V10.5 and V11 professional versions.
I am trying to go online to the PLC but keep getting a message saying No accessible devices found in network.
There are 3 PLC's on the network and 2 HMI's with IP Addresses in the 192.168.0.xxx range and a subnet mask of 255.255.255.0. I have set my laptop with the same IP address 192.168.0.xxx and the same subnet mask.
I can ping all devices and get a reply back from all of the PLC's and the HMI's but cannot get online, upload or download from any of them.
I thought it might have something to do with my PG/PC interface, but have read that the TIA doesn't use this method.
I feel I am missing something really simple.
Thanks in advance for any help.
