8.4.8 Batch-changing the cam data/limit switch output data
The cam data/limit switch output data stored in block No. 10 to No. 18 of the
memory cassette's extended file register area are imported by the PCPU of the
A273UHCPU/A173UHCPU (-S1) at power-on or reset to exercise control.
Using the sequence program, the cam data/limit switch output data imported by the
PCPU can be batch-changed.
Change the cam data/limit switch output data in the following procedure.
1) Write the cam data/limit switch output data to block No. 10 - No. 18 of the
extended file register area.
(Note-1)
↓
2) Make a batch change request of the cam data/limit switch output data (M2056:
OFF→ON)
(Note-2)
↓
3) Batch-change processing of the cam data/limit switch output data is executed.
↓
4) Reset the batch change request of the cam data/limit switch output data
(M2056).
CAUTION
(Note-1)
: In any of the following cases, do not change the cam data/limit switch output data (data in block No.
10 to No. 18 of the extended file register area).
• During write of cam data to PC from peripheral device (cam data area)
• During write of servo setting data to PC from peripheral device (limit switch output data area)
• At real mode to virtual mode change request (M2043: OFF→ON) (limit switch output data area)
• During cam data/limit switch output data batch-changing (M2056: OFF→ON)
(Note-2)
: In the following case, do not make a batch change request of the cam data/limit switch output data
(M2056: OFF→ON).
• During write of cam data to PC from peripheral device
In other than the above case, you can make a batch change request of the cam data/limit switch
output data (M2056: OFF→ON) in either of the real and virtual modes.
