High Speed Counter Encoder Module User Manual
3.1 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. W ord outputs contain user -defined counter
configuration setups and preset values.
T able 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.
