3.2 Head Station STL-BT1 (CC-Link)
The head station STL-BT1 is used in a remote station or a remote I/O station on CC-Link. It displays the
peripheral data of all connected STlite modules to the CC-Link.
The head station determines the physical structure of the node and automatically creates a local proc-
ess image from this with all inputs and outputs. This could involve a mixed arrangement of analog
(word by word data exchange) and digital (byte by byte data exchange) modules.
The data of the analog modules are mapped into the process image according to the order of their
position downstream of the head station.
The bits of the digital modules are compiled to form bytes and also mapped into the process image
attached to the data of the analog modules. Should the number of digital I/Os exceed 8 bits, the head
station automatically starts another byte.
The process image is subdivided into an input and output data area. The process data can be read in
via CC-Link and further processed in a control system. The process output data is sent via CC-Link.
The STL-BT1 can occupy up to four stations.
