Hello,
I can make tags in IGNITION for inputs outputs in the siemens S7 Protocol but can somebody help me making a tag for an analog flag?
Thanks in advance,
Jan
LOGO! PLCs are not supported by the S7 driver, since they cannot communicate with the S7 protocol. Looks like some of them support Modbus, though.
EDIT: Maybe they can? I'm seeing conflicting info online. The address syntax is available in the docs, but if you can provide more info about the address of the tag on the PLC, I can help get you an exact Item Path for the S7 Driver.
Hello
Thanks for your quick reply.
Yes they can and even with our Kepware server we do have all the information via S7 we want. even analog flags and other we can find . Our company is changing over to Ignition and i'm trying to find out more about other devices. like LOGO
Only inputs and outputs i can find with ignition but no analog values.
i want Input 1 on my LOGO: [Device]IX0.0 and that goes perfect. also Merker and outputs= OK
in logo you have to choose S7 Client:
in Ignition i can find the LOGO as S7 device and i do find values like in-and outputs but i want to find an analog flag and here i dont know how to make the tag.
The tag i am looking for is AM3 : Analog Merker 3
Thanks in advance,
Jan
What is the address used in Kepware? You can address the flags area with the Ignition driver using M in your address. E.g. -MX0.0
Hello,
I’ve tried allready several tags that responds well:
[device name]MX0.0 is working perfect
[device name]IX0.0 is working perfect
But what I use for a analog Flag?
Sorry, I'm not familiar with the Analog Flag area, learning as I go here. If this is the area typically addressed with AM, it's not supported within the Siemens driver.
Hello again,
this is the situation but i'll try on to find out
I1 responds on IX0.0 and M2 reponds to MX0.1
I'm looking to find a tag for AM3
Thanks anyway Jan
As far as I know, the Siemens driver does not support reading from the AM area. However, it does seem possible to read this area on a LOGO! PLC via Modbus. Let me know if you go this route, and I can try to help with the Modbus addressing.
Thanks again
on Modbus it works perfectly with HR531 for my AM but my boss wants me to try over S7 protocol.
On all our S7 PLC's it works fine you know but they use DB's and so on
this possibilities we don't have in a LOGO. I ve tried whit VB's and VM but no results
anyway some devices are LOGO and they wants me to find out what are the possibilities....
I'll let you know what is possible in S7 protocol with LOGO when i find out.
Thanks for your time
Jan
Thanks for the info, Jan! If the Kepware driver can read it, it may very well be supported within the S7 protocol, but unfortunately this is not an area that is supported within the Ignition driver. The only areas you can address with this driver are:
- Inputs
- Outputs
- Flags
- Data Blocks
- Counters
- Timers
Good luck with your testing, and feel free to reach out with more questions or info.
Hello Cody, Good news!!
I never give up so here is what i was looking for. 44 is the value for AM3
My Force on T1 S7 is 44 Ton in AM3 and this what i was looking for.
I found more help on the siemens forum: VB1=DB1.DBB1 and i did that before on S7 300 I can give more exemples but this forum only give 2 attachments...
In the LOGO i had given the name of VB2 For AM3 : and to read it with the Kepware server i used VB3.
TSAP is 30.XX when you use S7300 to read the LOGO. TSAP20.00 is standard for LOGO but also for S7 200 ( we are expecting some machines with S7 200 and thats why the boss wanted to use the siemens protocol)
The tric whit DB1,I2 it was a little bit of searching but io think this is always when you look for tags. I do have exemples from normal S7300 PLC's where i do the same.
Thanks anyway,
Jan
Cool, glad you got something working! To clarify for my understanding, you are mapping AM3 to VB2, then mapping VB2 to an offset within DB1?
Hello Cody,
Yes exactely. I allready left the company(Europe)
AM3 (Analog Merker 3) to VB2 ( Variabel Block 2) and then VB to DB1
VB is something you have to make when you change the LOGO to S7 connection. When you don't make it then you can't find it...
LOGO: "Tools"-->Ethernet connections--> allow S7 acces as client from your server ( you have to click right on the mouse) then double click on the connection you made-->"Connection (S7 client of IP adress)" and you arrive in a new screen --> TSAP is standard for LOGO or S7200 the TSAP for the server you have to make : in my case S7 300 i searche via IGNITION so i give it 30.01 and the richt IP adress. her you can create your VB1-2-3-etc.... and then via IGNITION you hvae to find VB2 (in my case) via: DB1 komma I2.
The komma and the I is something i had to ad also earlier when I was making Tags in IGNITION true a S7300 connection.
Sory for my explanations but first my English is not very good and second i'm not very IT...
But you start looking in DB1 and then a komma and than "I" and then 2

Good find! Thanks for sharing.
