1.2 Mapping: "xReset" (global variable) to %IX0.0 in %IW2
– "xReset" is mapped to the first bit in %IW0 of FGEN-IOM88-5001. This is done in the
"ModbusTCPSlave I/O Mapping".
– Double click the field "variable" in the respective line. Use the "..."-button to open the dialog box
"Input Assistant" .
– Select the variable to be mapped. "xReset" can be found in the global variables as it has been
defined there, see CODESYS: Global variables.
– Confirm with "OK". A "1" at bit %IX0.0 will now reset the counter to zero.
