Sending variable from S7-200 to S7-300 via EM277
Hello people,
I have established communication between a S7-200 and a S7-300 via profibus DP using an EM277 module. The network is well configured and i´m using a 32 Bytes Out / 32 Bytes In configuration on the module. I am able to send the bytes i need, but i also need to send one Double Word variable. How can i do that ? Suggestions?
Thanks in advance,

Tool for I/O distribution
Hi,
I am looking for a tool to make I/O distribution in a PLC of around 1000 I/Os. I have a lot of redundant signals (2oo3, 2oo2) and I have to make a consistent distribution in the modules and racks considering some criteria: different channels of redundant signals in different racks, etc. Normally I have done this manually but I wonder if there is a tool to do this much faster and without mistakes.
Builders from manufacturers, like TIA portal from Siemens or IAB from Rockwell, are of course very product oriented, they are a great help to select the right hardware, as far as I know they are not able to distribute redundant I/Os.
Anybody knows if a tool like this is available?

Conversion
Siemens S7-300........I can convert from INT to DI.....and from DI to REAL. I don't see any standard method of going backwards from REAL to DI and from DI to INT
My actual application needs to go from REAL to INT (DI to INT is kinda dumb)
Thanks, Bob

Problem - The statements are not being processed
I may have overlooked something obvious since I have little experience with Siemens. I took an existing S7 (CPU 314) program that I first checked to see if the offline copy the OEM left me was up to date by doing "compare blocks." It seemed to be, so I went to the offline editor and edited an existing function FC6 to add on one more network at the end of the folder. This was after I added a few new symbols of my own and saved them. I saved and compiled FC6 then pulled down Download from the PLC menu with just that block highlighted. It asked me if I wanted to replace FC6 and said yes. The addition I made is showing up in the online file. When I do a compare block for offline/online it is equal. When I click on monitor then highlight my new network I added, the RUN bar at the bottom stops scrolling, usually nothing is shown to the right in the RLO,STA,STANDARD monitor columns (this is a STL program), and the message at the bottom of the screen says "the statements are not being processed." I tried once more this morning to make sure the offline was saved, compiled, error free, etc. and downloaded it once again. This time every once in awhile I get some numbers in the monitor chart to the right (RLO,STA,STANDARD) but 99% of the time the run bar is frozen and the "statements are not being processed" message is there. When I click on Network 15 the run bar scrolls fast and the monitor chart shows up within seconds. When I go back to 16 the run bar freezes and after 10-30 seconds the monitor chart will fill in. It's almost as if the network 16 is trying to work but the update rate is unbelievably slow. I don't know what to make of it. I've searched the internet and my programming manual for a couple of hours for this "statements are not being processed" message and have found nothing to help at all so I don't know what it is trying to warn me that I've done wrong. I'm a little confused since I simply added in a network to an exisiting block with a few new symbols. What did I miss? Did I violate some rules about STL networks? I couldn't find any training material like I wanted about how much you can put in one network but the OEM has many much bigger networks in this program. I had considered making this several different networks but it's all one item. I should have put a title on the network that says "trigger to OPC server and reset." I supplied a screen shot of my network and captured it after the monitor items showed up to the right. Thanks!

Siemen 226 CPU NG connecting Proface
Hi,
Had anyone Have this problem, where the Siemen 226 CPU (s7 200CN) 6ES7 216 2BD23 0XB8 disconnect the Proface Model 3580207-02 AST3301-B1-d24 cause Damage to PLC comm port?
I had just replace the CPU after the machine running for 20 years, it was running fine for 3 months, then Comm Port 1 fail, then i replace the touch screen port to Comm Port 0, it run for few more month also the same problem occur. the CPU is still on run mode.
Can it be the grounding issue? or some other thing i need to check?

Connecting Siemens S7-1200 to WMS
I am curious as to how I can connect my Siemens PLC to a Warehouse Management System.
We will be scanning totes, from there taking the tote number and sending that to the WMS. Then the WMS will send me back the desired lane number.
I don't know where to start on this task. Please help.
Thanks
