Configuration

micrologix driver configuration

Each I/O point (e.g. B3:0/0) must be associated with an element of the PLC data file. Note that you can use any data file for Bool, Float and Integer but the following rules apply:

  • For Bool Inputs/Outputs, Count represents the number of bits. This means that if you would need 32 bits for Bool Inputs you would have to define, at least, 2 elements (Word) in the corresponding data file.

  • For Float and Integer points, Count represents the number of elements (Word).

When connected to a PLC, non-existent tags or tags with an error are grayed out. Hove the mouse cursor over a grayed out point to get relevant information about the error.

Auto connect Periodically tries to connect to the PLC until a successful connection is established.
Model PLC model.
Firmware PLC firmware version (only required for MicroLogix 1100).
Host PLC network name or IP address.
Bool Inputs Each point corresponds to a bit of an element (Word) - (max 128).
Bool Outputs Each point corresponds to a bit of an element (Word) - (max 128).
Float Inputs Each point corresponds to an element (Word) - (max 32).
Float Outputs Each point corresponds to an element (Word) - (max 32).
Int Inputs Each point corresponds to an element (Word) - (max 32).
Int Outputs Each point corresponds to an element (Word) - (max 32).
Default Each point corresponds to an element (Word) - (max 32).
