[foxboro] RE : Accum value of a CALCA block

B0193AX says that the range of a real is 10 power -38 to 10 power +38
The accumulator can be a real.
 
It would be interesting to see what is displayed if you connect to the block's 
.M24 parameter as the accumulator goes through the full range of a real.
 
The .RO01 of the CALCA has no configurable range. The default display is 
limited to four decimal places and will read 10 digits on the high side.
 
Not sure what OMGET will show you.

Not positive I understand the question but at any point in the CALCA
steps you can store a value in one of the 24 Memory registers provided
for use by the CALCA block. You can then watch the .M01 through .M24
values on the block detail display or display the value on your graphic
by connecting to:
CMPD:CALCA_BLK.M01 through .M24

An example from the CALCA section of B0193AX manual follows:

STEP12 IN 9       Loads accumulator with value 9.0.
STEP13 STM M05    Places value 9.0 into M05.
STEP14 LACI M04   Loads accumulator with contents of M05 (9.0).
STEP15 OUT RO01   Outputs accumulator value of 9.0 to RO01.
