External Loop Setting (Parameter
Address Setting)
GW
Sets the external loop parameter
address
Syntax GW p1,p2,p3<terminator>
p1: Loop number (Ext1 to Ext16) (Ext1 to Ext4
on the CX1000)
p2: Parameter type (PV, SP, OUT, Mode, R/L,
S/R, Alarm, SP.No, PID.No,AT)
(If the connecting model is “Other,”
parameters up to OUT are valid.)
p3: Register address (30001 to 39999, 40001 to
49999, 300001 to 365535, 400001 to 465535)
Query GW[ p1,p2]?
Example Set the register address of parameter PV of
external loop 3 to 40003.
