Allen-Bradley DF1 Global Parameters

This global parameter allows you to configure the use of single precision floating point values when accessing an Allen-Bradley device. A value of Y will configure ABDF-1 to use single precision floating point values on the specified port name, which is required by some devices (e.g. SLC devices). By default, the value is N, which configures the ABDF-1 to use double precision floating points, which is required by some devices (e.g. PLC-5 devices).

Note: if this global is configured to Y, a message will be written to the Project Status Logs indicating that single precision floating point values have been selected for the channel listed in the message.
