Program Examples
Section 4-3
as shown below, the data in each block is copied in turn to normal DM Area
words and downloaded to the Cam Positioner Unit. The process must be
repeated 6 times.
Initial Setup
The following dedicated DM Area word data and the ON/OFF data for the 48
cam outputs must be stored in advance using a Programming Console or
other Programming Device. Do not store the cam ON/OFF data in normal DM
Area words at this time. The data will be copied from the cam ON/OFF data
area in sequence by the program for downloading.
• Set the address of the first word in the DM Area that will be used to hold
the cam ON/OFF data for downloading. Here, the address is DM 0000.
• Set the number of cam outputs that will be downloaded for each data
transfer. Here, the maximum number (8) is used.
