GE Series Six to 9070 Program Conversion

GE Series Six to 9070 Program Conversion

GE Series Six to 9070 Program Conversion

(OP)
I have been given the task of upgrading a ge fanuc series six cpu to a ge 9070 plc. This involves keeping all of the original i/o and just replacing the series six cpu rack. The new 9070 cpu rack will run the old code which has been "converted" to run in the 9070. The 9070 will talk to the old series six racks through a S6PIO card.  The old series six has three i/o chains branching from io transmitters in the main rack. There is a CCM2 card in the old series six rack as well as 2 CCM cards in a remote i/o rack as well as some bus controllers. I guess these will have to be removed when the 9070 is installed and new 9070 cards will have to take their place ? Does anyone have any experience with this ( program conversion, S6PIO card, CCM cards ) ? Are there any pitfalls to watch out for.Any help will be appreciated.

RE: GE Series Six to 9070 Program Conversion

There is a software program offered by GE called "Softech" by GE Tools.  It will take the series six code and convert it to 9070 code for you.  Double check constants in Hex format, we had to clean some values after the code conversion.  You may also have to rename some variable names that begin with a number.  

Hardware-wise, there is little differences between the 9070 and the series six field I/O.  One issue we ran into was that all genius blocks with part #BBD100 needed to be changed to #BBD101 due to slightly different communication differences.  As far as communicating between the S6 and 9070, We set up a Global Genius Communication Network where the S6 and 9070 could see a block of memory from eachother on the same network line.  It was a somewhat small application, but there was plenty of space available for shadowing input signals.

The S6PIO supports expanded channel scanning, so you may be able to service the three I/O chains using just 1 S6PIO card.  The S6PIO card also supports intelligent devices such as IOCCM modules, ASCII/BASIC modules and Genius Bus Controllers.  A DP REQUEST instruction in Series Six code should be translated to an S6XWIN C block call in the 90-70 code along with one or more S6MOVE C block calls to move the data.

The CCM module in the Series Six CPU rack can often be replaced with an additional IOCCM module in an I/O rack.  Otherwise replace the CCM with a 90-70 CMM module.

There is no need to change Genius Blocks if the Series Six Genius Bus controller is kept.  The S6PIO supports genius I/O, datagrams and global data.
