74 DeviceLogix Capabilities

Digital Outputs from Function Blocks

Hardware

Discrete Output 0 through Discrete Output 7 are the eight hardware outputs

available on the module. If these tags are unused (that is, not mapped in the

DeviceLogix program), then there is a virtual mapping from the Data Byte

Output Assembly to the output point. This means that the output is under

control of the owning processor. If the Discrete Output is mapped in logic, it

is controlled by the module.
