8 Programming in SIMATIC STEP 7
8.1 General Information
SIWAREX FTA was developed specifically for operation with the SIMATIC S7.
The hardware set-up is described in detail in chapter 4 Hardware Configuration.
SIWAREX FTA is projected as a function module in the SIMATIC Manager. If the
SIWAREX FTA is not available in the component catalog for the SIMATIC Manager
(SIMATIC S7 classic) it should be installed using the HSP for the SIWAREX FTA
(HSP_2036_FOR SIWAREX_FTA_FTC on the configuration package CD).
Attention: if the SIWAREX FTA has already been installed via the Object Manager,
it must first be uninstalled before starting the HSP.
The example program – "Getting Started" is part of the configuration package. It
contains the S7 blocks necessary for operation of the SIWAREX FTA in SIMATIC.
The example program also shows how application software can be created.
We recommend using the example program and expanding it for different
applications.
Another level concerns programs that can be pre-fabricated for certain applications
(SIWAREX Multiscale and SIWAREX Multifill). These programs are professional
extensions of the example programs concerning functionality, number of weighing
procedures and/or materials.
8.2 SIWAREX FTA in the HW Configuration
During project planning for the hardware configuration in the SIMATIC manager,
the basic properties of the module are defined:
-
The peripheral address of the module
-
Diagnostic alarm enable
-
Process alarm enable
-
Behaviour for CPU stop
SIWAREX FTA requires 16 bytes in the input and output areas.
