Cryo-con Model 24C
Remote Programming Guide
LOOP commands
Loop commands are used to configure and monitor the controller's temperature
control loops.
Loop 1 is the controller’s primary heater output channel. The Model 24C has three
ranges.
Loop 2 is a secondary output. The Model 24C has a single range linear heater.
LOOP
{1 | 2 | 3 | 4}
:SOURce
{A | B | C | D}
Sets and queries the selected control loop's controlling input channel, which
may be any one of the four input channels.
LOOP
{1 | 2 | 3 | 4}
:SETPt <setpt>
Sets and queries the selected control loop’s setpoint. This is a numeric value
that has units determined by the display units of the controlling input channel.
Values above the one set in the maximum setpoint, or below zero are
rejected.
LOOP
{1 | 2 | 3 | 4}
:TYPe
{
OFF
|
PID
|
MAN
|
TABLE
|
RAMPP
}
Sets and queries the selected control loop’s control type. Allowed values are:
Off
- loop disabled
PID
- loop control type is PID
Man
- loop is manually controlled
Table
- loop is controlled by PID Table lookup.
RampP
- loop is controlled by PID, but is in ramp mode.
RampT
- loop is controlled by PID Table lookup, but is in ramp mode.
LOOP
{1 | 2 | 3 | 4}
:TABLeix
<ix>
Sets and queries the number of the PID table used when controlling in Table
mode. Six PID tables are available to store PID parameters vs. setpoint and
heater range. <ix> is the loop’s control PID table index.
Table index is in the range of 1 through 6.
