Transferring Data
Parameters and data can be transferred between the CPU Unit and the PCU
using one of the 3 methods explained below. The different types of data can
be classified into the following groups (it is possible to send only parts of these
groups):
Positioning sequences, speeds, positions, acceleration times, deceleration
times, dwell times, and zones
1,2,3...
1.
Writing and reading data to and from the PCU using a data transfer bit.
(Refer to
5-2 Writing Data with the WRITE DATA Bit
and
5-3 Reading Data
with the READ DATA Bit
.)
Large amounts of data can be changed and data can be read by turning
ON a data transfer bit using, for example, OUT in the ladder program.
2.
Writing and reading data to and from the PCU using the IOWR and IORD
instructions. (Refer to
5-4 Writing Data with IOWR
and
5-5 Reading Data
with IORD
.)
During CPU Unit operation, small amounts of data can be changed at high
speed and data can be read using the IOWR and IORD instructions from
the ladder program.
