(4) As setting range of the following setting items is changed by changing the input
range, the previous setting value may be out of the setting range after changing
the input range.
In this case, the setting items which have been out of the setting range detect a
write data error. Changing of the input range should be executed after having
set the value of the following items within the input range.
• Set value (SV) setting (buffer memory address: 34, 66)
• Proportional band (P) setting (buffer memory address: 35, 67)
• Alert set value 1 to 4 (buffer memory address: 38 to 41, 70 to 73)
• AT bias (buffer memory address: 53, 85)
• Upper limit setting limiter (buffer memory address: 55, 87)
• Lower limit setting limiter (buffer memory address: 56, 88)
• Loop disconnection detection dead band (buffer memory address: 60, 92)
• Scaling range upper limit value (buffer memory address: 197, 213)
• Scaling range lower limit value (buffer memory address: 198, 214)
• Zone 1 to 8 proportional band (P) setting
• Segment 1 to 16 set value (SV) setting*2
*1: Set by buffer memory address: 282 to 313, 538 to 569. (Refer to Section
3.5.1)
*2: Set by buffer memory address: 320 to 372, 576 to 628, 384 to 436, 640 to
692, 448 to 500, 704 to 756. (Refer to Section 3.5.1)
(Example) When changing the input range from thermocouple K to J at the set
value (SV) 1300 .
Thermocouple
As the set value (1300 ) is within the input range (-200 to 1372 ), a
K
write data error is not detected.
As the set value (1300 ) is outside the input range (-200 to 1200 ), a
J
write data error is detected.
