Global Communications
Data may be read from or written to the following memory types using Global data communications:
Memory Type | Description |
%I | Read discrete inputs from Genius BIU |
%AI | Read analog inputs from Genius BIU * |
%Q | Write discrete outputs to the Genius BIU Discrete Output table |
%AQ | Write analog outputs to the Genius BIU Discrete Output table * |
%GL | Read Global Data from Analog and Digital blocks Read Global Data from programmable controllers Write Outputs to Digital Blocks Read Global Data from other Genius devices (such as PCIM cards) |
%EO | Enable Outputs to Blocks Enable Outputs to Genius BIU |
%DO | Directed Outputs to Analog Blocks |
* Analog points configured in Discrete memory on a BIU must be configured to start on even-byte boundaries.
