About I/O Tags
There are two kinds of I/O tags: static and dynamic.
Static tags include:
• Device Input (DIP) - physical input point of the device
• Consumed Network Bit (CNB) - network input bit
• Fault Bit (FB)- device fault bit
• Status Bit (SB) - device status bit
• Device Output (DOP) - physical output point of the device
• Produced Network Bit (PNB) - network output bit
Dynamic tags are those created dynamically during configuration.
They are the referenced output bits of latch, counter, and timer
elements. Using reference bits can simplify your ladder logic.
