3-6-2 Set Value Read
Execute the following on the Programming Console for loops 1 and 2.
1, 2, 3... 1. Read the proportional band.
Default: SP = 100
°
C and PV = 98
°
C
c100 c001
0100 0098
Write the allocation change code “C010” to the output word of the relevant
loop.
c100 c001
C010 0098
Confirm that the input word of the relevant loop will become C010.
c100 c001
C010 C010
Write the set point to the output word of the relevant loop.
c100 c001
0100 C010
Record the value read from the input word of the relevant loop as the propor-
tional band.
c100 c001
C100 0400
2. Read the integral time.
Refer to the above procedure and replace the allocation change code
“C010” with “C020” and write it as the integral time.
3. Read the derivative time.
Refer to the above procedure and replace the allocation change code
“C010” with “C030” and write it as the derivative time.
4. Read the hysteresis.
Refer to the above procedure and replace the allocation change code
“C010” with “C040” and write it as the hysteresis.
