Example Code
Preliminary remark
Enclosed you will find the SIMOCODE pro and STEP 7 Project
example codes with which you can reconstruct the functionality
described here.
The example code is always assigned to the components used
in the Function Examples and functions as necessary. Any further
problems to be solved must be dealt with individually by
the user. However, the example code can serve as a basis.
Downloading the STEP 7 Project
To access the corresponding project file, open the proffered
"CD-FE-I-039-V10-proC.zip" file and extract this into any directory.
To download the S7 Project in the CPU you must have a connection
between the MPI interface of your PG/PC and the MPI
interface of the CPU.
Please proceed as follows:
■ First load the hardware configuration in the S7 CPU
■ Change to SIMATIC Manager
■ Activate the Module folder
■ Click the Load button
The assignment of the cyclical control and signal data that has
been exchanged between the DP Master and SIMOCODE once
in each DP mode is listed in the following table. The control
data is sent to SIMOCODE from the DP Master. SIMOCODE answers
by sending the signal data to the master module. The
CPU 315-2DP is the master in this example. In the PLC program,
access to the cyclical data is via the inputs (signal data)
and the outputs (control data).
Note
The program code for creating the control commands
to switch the direct starter on and off must be individually
created by the user.
The program code for further processing the
"EMERGENCY STOP" signal in the PLC must be individually
created by the user.
The "EMERGENCY STOP" signal is not safety oriented.
