(3) Operation of the forced output function
The forced output function operates as follows.
(a) Shift to a forced output status
When the value in Forced output command (buffer memory address: 204,
220) is changed to 1 (Forced output commanded), the manipulated value
(MV) at that point is stored in Forced output manipulated value (MV) (buffer
memory address: 205, 221). The value to be stored is Manipulated value
(MV) (buffer memory address: 13, 14) (-50 to 1050) scaled into a value
range of -200 to 4200.
(Example) When the manipulated value (MV) is 250 (25%), 1000 is stored in
Forced output manipulated value (MV) (buffer memory address:
205, 221). (Refer to the part
After a manipulated value (MV) was stored, 1 (With forced output command)
is stored into Forced output status flag (buffer memory address: 266, 522).
(b) In a forced output status
After 1 (With forced output command) is stored in Forced output status flag
(buffer memory address: 266, 522), any value can be set to Forced output
manipulated value (MV) (buffer memory address: 205, 221).
Setting a value into the area stores a manipulated value scaled into a value
range of -50 to 1050 (-5.0 to 105.0%) in Manipulated value (MV) (buffer
memory address: 13, 14).
The following figure is an example of when 1000 is set to Forced output
manipulated value (MV) (buffer memory address: 205, 221).
