This driver provides an Ethernet connection to Allen-Bradley MicroLogix PLC.

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. Hover the mouse cursor over a grayed-out point to get relevant information about the error.

Configuration Setting	Description
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 256).
Bool Outputs	Each point corresponds to a bit of an element (Word) - (max 256).
Float Inputs	Each point corresponds to an element (Word) - (max 64).
Float Outputs	Each point corresponds to an element (Word) - (max 64).
Int Inputs	Each point corresponds to an element (Word) - (max 64).
Int Outputs	Each point corresponds to an element (Word) - (max 64).
Default	Click to reset to the default options.
