Section 5-3
READ DATA Procedure
1,2,3...
1.
Set common parameters. (Refer to
4-2 Common Parameter Area.)
m:
Set the operating data area either to DM or to EM.
m+1:
Set the beginning word of the operating data area (l).
m+2:
Set the axis parameter designation.
2.
Powering up again or restart.
The data for the common parameters set in 1 above will be enabled.
3.
Set the operating data area.
I+4:
Total number of words to be read from the PCU (Hex)
I+5:
Beginning address of PCU’s data area (Hex).
l+6:
The area in the CPU Unit (DM/EM) where the data will be stored.
I+7:
Beginning word address (Hex) of CPU Unit’s DM or EM area
where read data will be stored.
4.
Execute READ DATA.
Turn the READ DATA Bit (word n+1, bit 13) from OFF to ON.
The operations in (1) and (2) above are required when using the PCU for the
first time or when modifying the data in the common parameter area.
