PLC - Programmable Logic Controller
The following are examples of what is controlled by the ice & water vending machine’s PLC
The PLC displays a top-level series of numbers & a bottom-level series of numbers
• Top-Level = Inputs
• Bottom-Level = Outputs
The PLC can be programed and the functions can be altered by using the push buttons around the display
or by using software, both of which can be a complicated procedure. Bag of Ice PLC programing is dynamic
and changes often to improve the functionality of your ice & water vending machine. Before attempting any
manual PLC procedures please call Bag of Ice Technical Support for up to date instructions and or allow Bag
of Ice to make the PLC program changes on your behalf.
