In a ControlLogix chassis, if the tag for a device is Local:4:I:Data.7, which slot should you check for the I/O module?

In a ControlLogix chassis, the tag format Local:4:I:Data.7 provides specific information about the module's location and the data being accessed. The first part, "Local:4," indicates that the module is located in slot 4 of the local chassis. The "I" signifies that it is an input module, while "Data.7" refers to the specific data point or element within that module.

Since the module in question is specified as being in slot 4, it directly correlates to the address indicated in the tag. When analyzing such tags, recognizing the slot number associated with "Local:" is crucial for determining where to look within the chassis for the appropriate module. Therefore, slot 4 is the accurate choice to check for the I/O module referenced in the tag.
