4.2.3 Termination of Received Data

When data is received on either of the application ports, you must define in the

configuration when this data will be transferred to the ControlLogix processor.

Within the module, this is known as the termination type for port. When the

termination condition is met, the data will be sent from the port’s receive buffer

(data area of 4096 bytes) to the processor using the input image. This

termination type is set using a bit-mapped value, entered into the

GSC.CONFIG.PORTX.TYPE field of the configuration controller tags.
