FP7 Thermocouple and RTD Units User's Manual

Each unit attached to the CPU must be configured in an I/O map which is

registered in the CPU. The current I/O map can be displayed in the "I/O

map and unit configuration" dialog. It shows the slot numbers and starting

word numbers of the CPU and its expansion units. I/O addresses are allo-

cated based on the starting word number.

To display the current I/O map and starting word number of a unit in Con-

trol FPWIN Pro, proceed as follows:

1. Open project

2. Double-click "PLC" in the navigator

3. Double-click "I/O map and unit configuration"

4. Double-click the desired slot number

Please refer to the CPU Hardware User's Manual for details on entering

and uploading I/O maps.

After A/D conversion, the digital output values are written to the CPU's in-

put area (WX) and processed. Status flags are also allocated to the CPU's

inputs.

The I/O addresses in the table show offset addresses. I/O addresses actu-

ally allocated are based on the first word number allocated to the unit.

Example: If the first word address is 10, the address numbers for the digi-

tal output value and the error flag on channel 0 will be WX10 and X11F,

respectively.
