GX20-1/GP20-1: C001 to C300
GX20-2/GP20-2: C001 to C500
GX10/GP10: C001 to C050
Specify communication channel
numbers.
Communication channel raw
data (release number 3 and
later)

GX20-1/GP20-1: RC001 to
RC300
GX20-2/GP20-2: RC001 to
RC500
GX10/GP10: RC001 to RC050
Reads the raw values (as-is) applied
to the communication channels.
Specify communication channel
numbers.
Internal switch status S001 to S100 1 or 0.
Flag F01 to F20 1 or 0. Use the event action function
to set the flag (for details, see section
1.6).
Recording status (release
number 2 and later)
4
GX20-2/GP20-2: REC01 to
REC12
GX10/GP10/GX20-1/GP20-1:
REC01 to REC06
Recording (1), not recording (0).
If the multi-batch function (release
number 3 and later, /BT option)
is not in use, “REC01” shows the
recording (memory sampling) status.
If the multi-batch function is in use,
“REC01” to “REC12” show the
recording (memory sampling) status
of each batch group. Recording
status of invalid batch groups is 0.
1 /MT option
2 /MC option
3 /MC option
4 REC02 to REC12 are available in release number 3 and later.
