5-4 Controller and Programmer
On 5G output models (output catalog No. appended with 5G), you can choose between use as a controller or a
programmer. Set this in setup data C 1 8. You can also choose between controller or programmer functions even if
the DCP301 is used for program operation or constant-value operation.
The DCP301 is limited to use as a controller at all times on other models.
● Controller
When the DCP301 is used as a controller, PID control operation is carried out according
to PV, SP AND PID setting values, and the resulting manipulated variable (MV) is out-
put as an analog output.
ON-OFF control, heat/cool PID control and 3-position-proportional is also possible de-
pending on the type of output supported by the model of DCP301.
In the MANUAL mode, the MV can be incremented or decremented in the basic display
state by the console keys.

● Programmer
When the DCP301 is used as a programmer, PID control operation is not carried out, and
the SP is output in the scaled 4 to 20mA range.
In the MANUAL mode, the SP can be incremented or decremented in the basic display
state by the console keys.
