<strong>MODBUS</strong>/<strong>TCP</strong> <strong>Fieldbus</strong> <strong>manual</strong><br />
The I/O sub-tab allows the user to exercise functions 0x01 (read<br />
multiple coils), 0x05 (write single coil) and 0x0F (read multiple discrete<br />
inputs).<br />
The read coils and inputs will display two ways:<br />
1. The checkboxes will display as checked if the I/O point is active.<br />
2. The total active points will display as Binary Coded Decimal (BCD)<br />
in the text fi eld with a range of 0 – 15.<br />
NOTE: The I/O points must be confi gured to the desired function, active<br />
state and sink/source using the manufacturer specifi c function codes<br />
0x41 (write specifi c) and 0x42 (read specifi c).<br />
By default the I/O points are confi gured as general purpose inputs, active<br />
when low, sinking. See section 4.3 of this document.<br />
