6.8 Basic Setting Commands (Control)
Tuning Setting
GU
Turns Off/On the tuning item
Syntax GU p1,p2,p3,p4,p5,p6,p7,p8,p9
p1: Loop number (1 to 6, Ext1 to Ext16) (1 or 2,
Ext1 to Ext4 on the CX1000)
p2: Item number (1 to 21)
p3: Item Off/On (Off, On)
p4: Item ID*
p5: Item name (alphanumeric characters)
p6: Register address (5- or 6-digit number)
(cannot be specified for internal loops
excluding “Others”.)
p7: Decimal point position (0 to 4) (cannot be
specified for internal loops)
p8: Control span low limit (cannot be specified
for internal loops)
p9: Control span high limit (cannot be specified
for internal loops)
*: For internal loops
SP, A1, A2, A3, A4, P, I, D, OH, OL,
MR, H, DR, PO, SB1, FL1, SB2, FL2,
RT, RBS, RFL, W01 to W36
For external loops
SP, A1, A2, A3, A4, P, I, D, OH, OL,
MR, H, DR, DB, PO, ETC (if the
connection model is set to “Other,” only
ETC is valid
Query GU[ p1,p2]?
Example Set the item of internal loop 6 number 18 to Off.
GU6,18,OFF
Set the item ID of internal loop1 number 21 to A1
and item name to “Item”.
GU1,21,ON,A1,Item
Set the item ID of external loop 12 number 1 to
ETC, item name to “etc”, register address to
40003, decimal point position to 1, control span
low limit to –10000, and high limit to 10000.

UT520,UT550,UT750,Others
Query GJ[ p1]?
Example Set communications of external loop 1 to On,
Modbus address to 2, connection model to
UT450, loop select to 1
st
loop, tag to “TAG1”,
and tag comment to “Ext1”.
GJEXT1,ON,2,UT450,FIRST,TAG1,Ext1
GK External loop parameter auto
reading execute command
Syntax GK p1,p2
p1: Loop number (Ext1 to Ext16) (Ext1 to Ext4
on the CX1000)
p2: Auto reading (1, 2, 3)
1: Basic settings
2: Parameter address
3: Tuning setting
Query GK[ p1]?
Example Automatically read the basic settings of external
loop 16.
GKEXT16,1
GV External loop parameter 4,
parameter type/decimal point
position and unit
Syntax GV p1,p2,p3,p4
p1: Loop number (Ext1 to Ext16) (Ext1 to Ext4
on the CX1000)
p2: Parameter type (PV, SP, OUT)
p3: Decimal point position (0 to 4)
