9200 MMI Protocol Register Mapping
July 16, 2004
The 9200 maps the most common parameters to be as compatible as possible to a MMI FDP VER. 3.X
commonly referred as a Dualpro. (Dualpro). Reads of table 0 blocks 0, 1, 6, 7, and 8 are mapped. Table
31 block 0 is mapped for probe maintenance data only. Data is mapped into the Dualpro format only if
there is a reasonable correlation between the 9200 parameters and the Dualpro parameters. Other values
in these blocks are returned as 0.
The 9200 will return an error message instead of data under the following conditions:
Table number greater than 12, except table 31 block 0.
Block number greater than 9.
Block number greater than 3 except for table 0.
Reads of blocks not mapped or returning an error read the equivalent Modbus registers. For table zero the
24 words (registers) start at the block number times 24. Therefore, block 2 would start at Modbus register
48, block 3 at 72, etc. For tables 1 through 12 the start register of the block is equal to 900 plus the table
number times 100 plus block number times 24. Tables 1 through 12 access the slave instrument data on
the 9200.
The parameter write command (X) is mapped for seven parameters.
PF1 is mapped to CO factor.
PF2 is mapped to H2 factor.
Ref Num is mapped to ID num.
Set point 1 is mapped to Loop 1 set point.
Set point 2 is mapped to Loop 2 set point.
Alarm 1 set point is mapped to Alarm 1 set point.
Alarm 2 set point is mapped to Alarm 2 set point.
The Program control command (P) should be able to start and stop SSi recipes.
