User guide
When it receives the bus configuration, the S7 CPU makes cyclic attempts to establish a connection to the IO
device. However, because the device is not yet active, an error status is displayed on the CPU by means of the
red LEDs (SF, BF2).
If the device starts up at a later time, the CPU detects this automatically, the IO data exchange is recorded, and
the error LEDs are extinguished. However, the firmware for the IO device must first be compiled, downloaded to
the device, and started.
2.6 Creating a PROFINET IO Configuration with NCM PC
The NCM_PC directory on the DK-ERTEC 200 PN IO CD contains a finished NCM PC project for isochronous
real time communication suitable for the device application. It includes the following:
• Bus configuration with CP1616 IO controller and PNIO device
• Configuration of the inputs and outputs of the PNIO device
We recommend that you use this example unchanged for the initial commissioning. Unzip the
EB200_PNIO_NCM_PC.zip project in the NCM PC Directory Drive:\……\Siemens\SIMATIC_NCM\s7proj
and
open the project with the NCM PC Manager. Select Configuration
to start NCM PC Config with the settings.
1. Save and compile
2. Download the bus configuration
3. Device name EB200PNIO for device in this example
Figure 8: Configuring a PROFINET Device with EB 200 in NCM PC CONFIG
The screen form shows the bus configuration, consisting of a CP1616 as the IO controller and an ERTEC 200
evaluation board as the IO device. The table shows the module configuration for the selected device. In the
example shown here, 2 modules (one 64-byte input module and one 64-byte output module) have been inserted
in slots 1 and 2. The I-address and O-address columns indicate where the I/O data in the process image of the
CP1616 are stored. For example, the data of the digital input module on slot 1 are stored in the process image in
input bytes EB256 to EB319.
