4.3 Input (XW), Output (YW) and configuration (MW) Register allocation
For Digital Expansion Models:
The Physical Inputs and Outputs in the Expansion modules are accessed using XW and YW registers respectively.
The digital inputs in the Digital Expansion Models are updated in the (Input) XW registers.
The expansion model may have XW or YW registers depending on availability of the physical input/outputs for that
model type. As given in Section 7.2 ‘Memory Allocation of XW, YW and MW’, different expansion models have
different number of XW, YW and MW memory assigned for them in the base model.
e.g. The digital expansion model FLD1600 has 1 XW register memory assigned for it.
There are no outputs so no YW memory. So the input condition of FLD1600 is read in Input Register XWxx00. Same
inputs are shown in the input coils Xxx000 to Xxx015. Here xx denotes the slot number in which the expansion
model is connected to FlexiLogics.
Similarly, outputs register for FLD0016R model is YWxx00. For FLD0808R model it has one XW and one YW, but
only 8 bits are used. Other bits are not used.
For Analog Expansion Models:
Analog Inputs and Outputs in the Analog Expansion models are accessed using XW and YW registers respectively.
The type of input channel is configured from configuration registers MW.
