Control Commands
CA
Switches between auto, manual,
and cascade control
Syntax CA p1,p2<terminator>
p1: Switch between auto, manual, and cascade
operation (0, 1, 2)
0: Automatic switching
1: Manual switching
2: Cascade switching
p2: Loop number (1 to 6) (1 or 2 on the CX1000)
Example Set the operation mode of loop 4 to cascade.
CA2,4
OC Switches run/stop
Syntax OC p1,p2<terminator>
p1: Switch run/stop (0, 1)
0: Stop
1: Run
p2: Loop number (1 to 6) (1 or 2 on the CX1000)
Example Switch loop 5 to run.
OC1,5
RL Switches remote/local
Syntax RL p1,p2<terminator>
p1: Switch remote/local (0, 1)
0: Local
1: Remote
p2: Loop number (1 to 6) (1 or 2 on the CX1000)
Example Set the input of loop 1 to remote.
RL1,1
OS Stops/Starts control operation
(common to all loops)
Syntax OS p1<terminator>
p1: Stop control operation
0: Stop
1: Start
Example Start control operation.
OS1
SN Switches target setpoint number
Syntax SN p1,p2<terminator>
p1: Target setpoint number SP (1 to 8)
1 to 8: Target setpoint number 1 to target
setpoint number 8
p2: Loop number (1 to 6) (1 or 2 on the CX1000)
Example Set the target setpoint number of loop 5 to 8.
SN8,5
PX Resets/Runs program
Syntax PX p1<terminator>
p1: Switch reset/run (0, 1)
0: RESET
1: RUN
Example Start program operation
PX1
HU Holds program operation
Syntax HU p1<terminator>
p1: Hold program operation (0, 1)
0: Release hold
1: Hold
Example Hold the program operation.
HU1
AD Advances program operation
Syntax AD p1<terminator>
p1: Segment advance request during program
operation (1)
1: Segment advance request
Example AD1
PN Switches the pattern number
Syntax PN p1<terminator>
p1: Program pattern number (1 to 30)
1 to 30: Pattern number 1 to pattern
number 30
Example Set the program pattern number to 10.
PN10
HJ Changes the manual output
setting
Syntax HJ p1,p2<terminator>
p1: Manual output setting (–50 to 1050 (–5.0 to
105.0%)). However, within the output high-
limit and low-limit.
p2: Loop number (1 to 6) (1 or 2 on the CX1000)
Example Set the manual output setting of loop 1 to 25.0%.
HJ250,1
HV Requests auto tuning
Syntax HV p1,p2<terminator>
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: 0 OFF
1 Carry out PID number 1
2 Carry out PID number 2
3 Carry out PID number 3
4 Carry out PID number 4
5 Carry out PID number 5
6 Carry out PID number 6
7 Carry out PID number 7
8 Carry out PID number 8
9 all
Example Execute PID number 1 of loop 1.
