So I installed release 1.09.003
So... is it working? Or do you still have to test?

Has this been working before, or is it the first time for you with Citect and S7-1500 ?
If this the first time, then I can imagine a few things that you must be aware of.
I doubt that Citect can read S7-1500 addresses symbolically (I might be wrong).
If I am correct, then you must setup each tag with absolute address access.
And, the accessed variables in S7-1500 must be set to non-optimized.
And, PUT/GET access must be enabled on the S7-1500 - default is not enabled.
When setting up the connection, it is basically the same as for S7-300, except that the rack/slot which was always 0/2 in S7-300 is always 0/1 in S7-1500.
If the S7-1500 has enabled PUT/GET, and the tags are accessed with absolute addresses, then it is exactly as for an S7-300 - except for the rack/slot.
So even legacy software that knows nothing about S7-1500 should work as long as it did work with S7-300.
edit: I studied the help pages, and it seems that for S7-1500 the only thing you must specify is the IP address. So the rack/slot is probably implied for S7-1500.
Any help pages for the setup of the tags ?
The whole point of the S7TCP driver is to read/write addresses symbolically. I managed to get the older PSDIRECT driver working with the S7-1500 using PLCSIM Advanced V2.0 SP1 (originally it worked with S7-300), and in this case I had to set to non-optimized using absolute addresses.
No. It's only used with the PSDIRECT driver only. No "middleman" with the S7TCP.Do I have to use PSDirect as middleman to use S7TCP driver?
Yes.If I to use PSDirect then I have to use absolute addresses, is it?
No it is not working. I get the warming message saying it is not the final release or need license. Here is the image.

No, I have no experience with Citect (except 20 years ago, and that was with an AB PLC).ZamkuD said:When you say basically it is same as S7-300, you mean use S7NT driver?
I didnt say anything about that. But I do know that Citect supports various alternative ways to communicate with Siemens, amongst these are Simatic Net (S7API driver) or OPC.ZamkuD said:So, you have to use middleware like SImatic Net or PSDirect software to talk to S7-300 CPU. So DO I need to configure any middleman software to configure it.
ZamkuD said:Do I have to use PSDirect as middleman to use S7TCP driver?
Wow, that is confusing. The "direct" driver is actually not direct but requires a middleman.No. It's only used with the PSDIRECT driver only. No "middleman" with the S7TCP.

How you simulated using PLCSIM? Maybe I can try that and see if it is working. Then I at least know that driver is working.
