Command
MF Filter
When the PV/SP Computation Function is OFF
Syntax MF p1,p2,p3,p4
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Input type (PV1, PV2, RemoteSP)
Note) RemoteSP is valid only when using
remote.
p3: Enable/disable filter (Off, On)
p4: Filter value (0 to 120 s)
Query MF[ p1,p2]?
Example Set the filter value of loop 1 PV1 to 60 s.
MF1,PV1,ON,60
When the PV/SP Computation Function Is ON
Syntax MF p1,p2,p3
p1: Control input channel numbers (CI01-CI10,
or CI01-CI05 with the CX1000)
p2: Filter (Off, On)
p3: Filter value (0-120s)
Query MF[ p1]?
Example Set CI03’s filter value to 60 seconds.
MFCI03,ON,60
RS Set the ratio
Syntax RS p1,p2,p3,p4
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Enable/disable ratio setting (Off, On)
p3: Ratio value (0.001 to 9.999)
p4: Rtio decimal point position (0–4)
Query RS[ p1,p2]?
Example Set the ratio value of loop 2 to 1.000.
RS2,ON,1000
Description Valid when remote input is selected with the GS
command.
Control Alarm
AT
Sets the control alarm
When p3=Off (no control alarm)
Syntax AT p1,p2,p3
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Alarm number (1 to 4)
p3: Enable/disable alarm setting (Off)
Query AT[ p1,p2]?
Example Turn off loop 1 number 1 alarm.
AT1,1,OFF
When p1=1 to 6
When p3=On (with control alarm)
Syntax AT p1,p2,p3,p4,p5,p6,p7
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: Alarm number (1 to 4)
p3: Enable/disable alarm setting (On)
p4: Alarm type*1
p5: Alarm standby (Off, On)
p6: Enable/disable relay setting (Off, On)
p7: Relay number*2
*1: PV-High,PV-Low,Deviation-High,
Deviation-Low,Deviation-H&L,
Dev-within-H&L,SP-High,SP-Low,
Output-High,Output-Low
*2: DI001 to DI006
DI101 to DI106
DI201 to DI206
RI001 to RI012 (expansion module)
Query AT[ p1,p2]?
Example Set loop 1 alarm number 4 as follows: Type:
deviation high/low limits alarm, standby and relay
output: On, activate relay 104 when alarms
occur.
AT1,4,ON,DEVIATION-H&L,ON,ON,DO104
AV Sets the control alarm value
When p1=1 to 6
Syntax AV p1,p2,p3,p4
p1: Loop number (1 to 6) (1 or 2 on the CX1000)
p2: SP number 1 to 8
p3: Alarm number (1 to 4)
p4: Alarm value
PV/SP alarm EU (0.0 to 100.0%)
Deviation high or deviation low limit alarm
EUS (–100.0 to 100.0%)
Deviation high/low limit alarm or within
deviation high and low limit alarm
EUS (0.0 to 100.0%)
Output value alarm (–5.0 to 105.0%)
Query AV[ p1,p2,p3]?
Example Set the alarm value of loop 1 SP number 1 alarm
number 1 (whose input type is set to TC type K
and alarm number 1 type set to deviation high
limit alarm) to the maximum value within the
selectable range.
