DL30-G USERS MANUAL EM-8571-G Rev.2
The GDO channels are used for the control output, alarm output, I/O mapping output, and schedule output.
The I/O mapping output has priority against other types of outputs if more than one function is assigned to a
single channel.
For those GDO channels with no I/O mapping output is assigned, the outputs are handled by OR logic of the
control, alarm, and schedule outputs.
