Siemens
It is based on TIA Portal with STEP7 Professional and WinCC Professional.
This review is by no means “complete”. It is the result of testing during 3-4 days.
Overall about TIA Portal.
TIA Portal is supposed to encompass all Siemens Simatic software products.
At the moment there are some holes in the line-up.
Lacking are the following:
Integration with DRIVES.
Safety.
S7-300 T CPUs.
S7-400 H CPUs.
WinCC redundancy.
CFC.
As to the S7 programming, it is worth noting that the new S7-1200 platform uses a different strategy compared to the older S7-300/400 platform. The programs for S7-1200 are compiled to machine-near instructions, whereas the programs for S7-300/400 are compiled to MC7 code. This means to end-users, that the instruction set for S7-1200 and S7-300/400 are not 100% identical. Also, when a programming functionality is released for one platform it isn’t necessarily released for the other platform. For example is the programming language SCL available for S7-300/400, but not for S7-1200. SCL for S7-1200 should be released at a later time.
It has been rumored that S7-300/400 will change to the same program strategy as S7-1200 sometime in the future. This will be logical so that there will be one uniform programming platform from top to bottom. TIA Portal requires a hefty computer. It does not run very fast on my average specified machine with
2GB RAM.
Starting a major activity, such as inserting an entire station, takes 20-30 seconds.
More irritatingly is that there is a minute delay for every activity in the editors that are used for coding the programs.
Also, the software has so many windows, menus, side-menus, tabs and sub-tabs, that you absolutely must have a large screen, and preferably two screens.
The next pages shows examples of some of the screens in TIA Portal.
