Module I/O Map

The HSCE module communicates with the PLC using word inputs and word
outputs. The PLC reads current count values, holding registers, and module
status bits from word inputs. Word outputs contain user-defined counter
configuration setups and preset values.

Table 3-1 lists the definitions for the word inputs (WX) and the word
outputs (WY), relative to a starting address of 1. If you assign a different
starting address for your I/O configuration, then all the address numbers
are relative to that starting address. For example, if you assign 9 as the
starting address, then WX1 through WX18 in the table become WX9
through WX26, and WY19 through WY32 become WY27 through WY40.
