Standard Input Types:
Code Input
J
J thermocouple -50 to 1400 F
K K thermocouple -110 to 2500 F
T T thermocouple -120 to 750 F
U 0 to 100%, 0 to 60mv
See hardware sections for scaling milliamp and voltage inputs when using the U
range.
Setpoints for millivolt inputs are in percent of full scale to the nearest 0.1% i.e.,
values from 0000 to 1000.
Setpoints for thermocouple inputs are in degrees F to the nearest degree.
Example: [NOTE: CR is carriage return, LF is line feed]
Command: C3J1200CR sets loop 3 as J thermocouple with 1200F
setpoint
Response: C3J1200CRLF
To Query for the input type and setpoint:
Command: C(n)QCR
Example:
Command: C3QCR
Response: C3J1200CRLF
7.3 CONTROL CONSTANTS
To set the proportional (gain) value:
K(n)P(abc)CR K is the constant indicator
n is the loop number 1 to 8
P indicates the proportional constant
abc is the value from 0 to 499
Example:
Command: K5P200CR sets the proportional gain loop 5 to 200
Response: K5P200CRLF
To query the proportional value:
K(n)PQCR
Example:
