Continuous Channel Data Read/Write Area

The GX/GP reserves up to 50 channels of register area per module.

For example, reading 100 channels of data from 10 analog input modules through normal

input registers would be inefficient because there would be a lot of empty registers.

The “continuous channel data read/write area” is a special area that enables continuous

reading and writing by limiting the number of channels of each module to 10.
