• Use the following formula to calculate the number of device points to be used when setting the PID control data:

Number of device points = 2 + 14  n (n: Number of loops to be used)

• Set each data as a binary value.

• If the number of device points for the number of used loops exceeds the last device number of the specified device, an error

occurs and processing is not performed. (Error code: 4101)

■For complete derivative

• Use the following formula to calculate the number of device points to be used when setting the PID control data:

Number of device points = 2 + 10  n (n: Number of loops to be used)

• Set each data as a binary value.

• If the number of device points used for the corresponding loops exceeds the last device number of the specified device, an

error occurs and processing is not performed. (Error code: 4101)
