Similar to a “property” class in C programming, PLCs can create custom data types that are a combination of the standard data types. These UDTs can then be assigned to groupings of tags in the PLC. The purpose of the UDT is to make scattered tag lists more compact and easier to rea...
These are the 7 types of PLC modules that are mostly used in modular or rack-mounted PLC. These modules are required for communicating and data exchanging through the input or output signal. If you are interested to learn PLC programming, read herestep to step procedure for learning PLC progr...
This is where a programmable logic controller comes into the picture, which doesn’t require any additional wiring and hardware to make sure of a change. Rather it requires a simple change in code, programming the PLC to only turn on the light 30 seconds after the switch is turned ON. So...
