Watlow 8PID Controller - Manual (Page 35)

Example:
Command: O7V0512CR suspends control and sets output to 50%
Response:O7V0512CRLF control is suspended, output fixed at 50%
To initiate PID control:
O(n)P0000CR O is the output indicator
n is the loop number
P is the start control indicator
0000 is a filler in the command
Example:
Command: O5P0000CR turn on PID control for loop 5
Response: O5P0213CRLF control is on for loop 5 output value is 213 out
of 1024 or 20.8% full scale.
The output value with control on is always changing as calculated by the control
algorithm.
To query the value of the analog output (control on or off):
O(n)QCR
Example:
Command: O7QCR query analog output/status loop 7
Response: O7V0512CRLF control is suspended value is set at 50%
Example:
Command: O5QCR query analog output/status loop 5
Response: O7P0786CRLF control is on, output currently is 786 (78.6% full
scale)
To set the time proportioning cycle time:
T(1)R(abcde)CR T is a time indicator
1 indicates general command, all loops
R indicates cycle time
abcde is a multiplier of the 55ms base
The range is from 0 to 29,999. The cycle time is calculated as 55ms plus 55ms times the
number entered. Thus the range is 0 to 29999 corresponds to 55ms to about 1650
seconds.
