10) Function Block
Numatics DeviceLogix nodes integrates all four types of function blocks; Boolean, Bistable, Counter and
Timers. A maximum of 72 function blocks, in any combination, can be used to develop a program sequence.
Boolean
AND
OR
XOR (exclusive OR)
NOT
NAND (negative output AND)
NOR (negative output OR)
XNO (negative output exclusive OR)
11) Ladder Components
Numatics DeviceNet/DeviceLogix nodes also have the ability to be programmed using the ladder editor in
RSNetworx. The ladder editor still integrates Latches, Counters and Timers, but instead of Boolean logic
blocks, it uses ladder rungs and branches. Also, instead of a maximum function block number, there is a
maximum amount of memory available for use. A percentage will appear in the message window below the
ladder editor window indicating how much memory the user still is allowed.
