Ignacio,
The value of RI01 should not change since all steps in the Calc Block up
to "END" or Step 50 are processed each time the Block is processed.

Subject: [foxboro] CALC block
Hi list, I have a question about the CALC block. Suppose that we have a =
CALC block with this instruction in the first line:
Step 1 IN RI01
and the same instruction is repeated in the 40th line, as follows:
Step 40 IN RI01
If the value of RI01 has changed in the time between those two steps in =
the same BPC, the values that the block will read will be different?.
Suppose that the CALC block and the block where the value of the RI01 =
comes from are in the same compound.
Thanks,
Ignacio Queirolo Olivera
