Siemens S7-1200 via CP1243-1 Additional Ethernet Interface

General Discussion
1

Hi,

Has anyone connected Ignition to an s7-1200 CPU via a CP1243-1 communications processor and successfully read CPU memory areas?

CPU on board Ethernet interface is being used for Profinet distributed IO on a local subnet.
CP interface is being used for connection to corporate subnet for programming changes and connection to SCADA.

Device has been successfully connected in the Gateway but when creating tags in designer quality is shown as bad.

Did you check these settings in the PLC?

Note that any changes to these settings require you to recompile software and hardware configuration and download both.

Thanks for the help.

After enabling 'permit access with PUT/GET communication' the tags are reading.

Hi, I'm trying to connect an S7 1200 PLC to Ignition software using the CP1243-1. The reasons are the same as yours. However, I don't see the tag communication reflected in Ignition. How did you configure communication between the CP1243-1 and Ignition software? Could you give me an example? Did you use some especial instructions, or was the access done directly through OPC UA on the PLC by CP1243-1?

Hi, have you worked with Ignition before? It sounds like you're fairly new to Ignition, but if not, I apologize for potentially spelling out stuff you may already know.

The original poster in this thread was using the Siemens S7-1200 driver for Ignition. Here is a link to the documentation for this driver: Siemens | Ignition User Manual

To put it more succinctly, in order to make this work you must follow a few steps:

  1. Configure the PLC to allow PUT/GET access and a few other settings. Compile the software and hardware changes, then download them to the PLC. This is described in this section: Siemens | Ignition User Manual
  2. Configure a Siemens S7-1200 device connection on the Ignition Gateway
  3. Configure tags with the appropriate OPC item path, data type, etc. in the tag browser within the designer.

There are a couple of Inductive University video lessons about how to connect to Siemens devices: Connecting to S7 Devices Video at Inductive University
