5.9 Communication Tasks
5.9.1 Reading Plots from the Communication Module
Overview
To load all plots on eight axes, the user would need to reserve 49,152 PLC registers. A single-
axis full plot requires 6,144 PLC registers. A plot of a single piece of information on one axis
requires 1,024 PLC registers.
The chart below can be used to determine the start of a given plot. n represents the axis number
(0-7). Remember that there are 1024 registers per plot, so for non-Allen-Bradley addressing, the
1024 sequential registers hold each sample, but for Allen-Bradley addressing, only 256 registers
fit in a register file. Therefore, the first 256 samples are in the register file calculated by the table
below as elements 0-255. The next 256 samples are in the next register file, and so on.
