Nc, Numerical Converter - Eaton easy800 Manual

5.23 NC, numerical converter

NC02 BCD +
>I1
QV>
This function block is available for easy800-SWD from device version 01 and
for easy800 standard devices from device version 04.
The numerical converter function block is used to convert a value of:
• BCD in binary value.
• Binary value in BCD.
The binary value is further processed in the device. For example it can be
added to a value. The binary value is displayed in the simulator as a decimal
value. easy800 device allows the use of up to 32 numerical converters.
Contacts and Coils
Coil NC..EN is used to activate the function block. If the coil NC..EN is not
active, the entire function block is deactivated and reset. The output value is
set to zero.
