Ok, thanks for your help, now I found out how it should work. Doesn't work right now but I'll get it... Chris

I have an AS-i/CC-Link Gateway according to AS-i specification 2.1 and it should work. But there must be some function in GX Developer to get the 16bit data. With a Siemens PLC it works like you send an order to the Gateway and get the 16bit data return, stored in the PLC memory (as far as I know). But actually I have a Mitsubishi PLC...

Thanks for your help. I have already set all network parameters as suggested in the manual. The point is that I can see the bits in the device monitor change (see screenshot), but that is no use as the 4x16bit output of my second slave is somehow transformed into a permanently changing 'number'. But I need the whole 4x16bit number and it is, actually, constant as someone who is used to this slave told me. I just attach some screenshots in a Word document, maybe they help... Attachment.doc

More infos ... here they come: I have a Q CPU (Q02HCPU) and a QJ61BT11 CC-Link Master (I/O address: 20). That is the Mitsubishi part. Connected to my CC-Link Master I have a Pepperl + Fuchs CC-Link/AS-i Gateway with two AS-i Slaves, but only one makes problems. One Slave has an analog Input 2x0...10V and a digital output (P+F, VBA-2E-G4-U) and my problem is that I don't know how to get this output data to my PLC. The Gateway has 4 bits for the input of one slave but the output data is much more. In the Device batch monitor I can see the bits (D1000.8 ... D1000.B) changing but thats no use. I just need the whole output data as a constant number. Now the main problem is that I don't know if there is a special function to get the output data stored in my D registers or how else I can cope with this problem. Would be great if someone could help me with this. Thx in advance. Chris

Thank you for this detailed response. I'll try to work my way through it, should help me with my problem.

Sorry, I don't know what you mean because I started to deal with this stuff only two weks ago, but I can try explain what I need: Actually I have a Mitsubishi PLC and CC-Link Master, a P+F AS-i/CC-Link Gateway and two AS-i Slaves. Now I have a 4x16bit input signal from a "Analog/Digital-Converter" - Slave which I'd like to receive with my PLC. Now I'm trying to find out how it works and someone told me that the function I have to use (transient transmission function) works similar to the mailbox function that is to be used for this purpose. At least it is used together with P+F products. That's all I know because I have to learn everything with user manuals and product explanations! Chris

Hey all Can someone please give me a rough overview of the mailbox function. What is it and how does it work. Would be great. Thanks in advance Chris

Thanks for the reply. What do you mean with modules. I have a Mitsubishi PLC and CC-Link Master. The rest is one CC-Link Gateway and two slaves. Do you mean the CC-Link Master if you say module. If yes, I don't know what module should have the Start I/O No 0000. Would be great if you could help me as I'm trying to figure this out since 3 days. It's quite depressing. Thanks Chris

Hey all I don't get along with these Mitsubishi manuals... What is a "Start I/O No". I just used 0020 in the 'network parameters' as said in the manual and it works, but with 0000 my network refuses to work. So what is this number standing for and why do I have to use 0020?? Thanks Chris

Thanks. I just registered as I will be working on my topic for the next six months. Seems as if I'll have to use this forum quite often.
