1BSCOPE OF DELIVERY, COMPATIBILITY
2.2 Compatibility
The SIWAREX U modules with the new order number 7MH4950-*AA01 are
fully compatible as regards software with the modules with order number
7MH4601-1*A01, which were produced from May 1997 to ca. November 2007.
As regards hardware, compatibility is also guaranteed, although from ca. November
2007 the modules work with a lower supply voltage for the load cells (6 V instead of
10 V), thus requiring less energy. The remaining hardware features (ports, frame
size, pin assignment, etc.) remain unchanged. In this way, the replacement of a
defective module 7MH4601-1*A01 with the order number 7MH4950-*AA01 is
possible without any difficulty.
Newly implemented was the possibility with the modules 7MH4950-*AA01 to
process the communication with the SIMATIC CPU alternatively via a function
block, which is prepared in the project "Getting Started". The functioning of the
new function block has already proven itself with the SIWAREX modules
(SIWAREX FTA, SIWAREX FTC, SIWAREX CS).
The program SIWATOOL U was also updated and corresponds in its design and
functionality to the SIWATOOL programs for SIWAREX FTA, SIWAREX FTC,
SIWAREX CS, and SIWAREX MS.
With the new SIWATOOL U, the modules with the order number 7MH4601-1*A01,
which were produced up to ca. October 2007, can also be operated. In this way,
the saved scale data (xxx.sku) can be imported into the new SIWATOOL U
environment and further used (xxx.swu).
