Programming Examples of 4-Word Mode
Example 2
Reading a Block of Memory Map Locations
The RTD Module occupies locations 002, 003, 004, and 005. This example
reads a block of data from module locations DM01 thru DM18 and stores it in
PLC memory locations D01001 thru D01018. Note that the lower two digits of
the two memory areas correspond. This was done intentionally to simplify
programming.

The latch enables the
read cycle until it
completes
The memory counter is
initialized to the starting
location...
then incremented on the
falling edge of PC Read
Finished...
until the final location is
reached. Then the read
cycle is complete
The memory address is
moved to word N+1
When the module has
read the address, this
latch is set
When the module has
provided the requested
data in word N+2, it is
moved to D00197
The handshaking is
controlled by the
response of the module
