This document describes the usage of a CC-Link IE Field Basic Slave Protocol Stack for GOAL. CC-Link IE Field Basic is abbreviated to CCLIEFB throughout this document.
Slave Stations
Using the GOAL CCLIEFB slave stack it is possible to setup a slave occupying 1 to 16 stations. Each station can be interpreted as a physical or virtual participant of the CCLIEFB network. To each of the stations there is a fixed amount of I/O data with fixed size, called Link Devices. I.e. to exchange more I/O data the slave may occupy more stations.
Table 3: Link Devices per station.
Link Device | Type | Size | Master access | Slave access |

RX | Bit Input | 64 bits (8 bytes) | read | write |
RWw | Word Output | 32 words (64 bytes) | write | read |
RWr | Word Input | 32 words (64 bytes) | read | write |
