4 HSL Slave Modules
The HSL is a master-slave network system, which features an
innovative distributed architecture that modularizes the communi-
cation, I/O functions and signal termination. ADLINK provides
slave I/O modules and terminal base to meet your particular appli-
cations requirement including discrete I/O, analog I/O, and motion
control. As for motion control module, please refer to the HSL-
4XMO user manuals.
Slave I/O Module: There are three groups of the slave I/O module
with individual dimensions. The slave I/O module gives the termi-
nal base different I/O capability. To identify each slave I/O module
in a HSL network, a module type electronic data sheet is inherent
in the module itself. And the slave I/O module located by address
ID, which is selectable by a 6-bit DIP-switch. Depending on differ-
ent I/O supported, every slave I/O module may consume 1 or 2
address ID. Since the greatest ID number in a HSL master is 63 (6
bit and ‘0’ reserved for master), there are at most 63 slave I/O
modules in one HSL master.
Terminal Base: The job of terminal base (TB) is offering an easy
wiring media. Both power and signal wiring go from terminal base
into the slave I/O modules. Also, the RJ-45 connector used to link
the masters to all the slave I/O modules on it. With the help of TB,
the slave I/O modules are hot swappable without interfering with
other modules in the same HSL network.
U series: In addition to Terminal Base products, ADLINK also
offers the slave modules which were named U-series. U-series
slave modules offer I/O signal wiring on module top directly. It is
more compact size than Terminal Base slave modules, moreover,
it offers several kinds of I/O interface to perform signal linking.
HUB/Repeater: HSL-HUB/Repeater provides customers sub-sys-
tem idea for different topology use.
Wiring Cable: The communication wiring cables among the HSL
master and I/O modules are standard 100 Base/TX with RJ-45
connectors. There are exactly the same as commercial Ethernet
cables.
