1 Introducing HSL

1.1 The HSL System

The HSL is an innovative distributed I/O technology that enables
time-deterministic scanning of thousands of I/O points in millisec­onds using master-slave architecture. The HSL master board
comes in PCI or PMC form factors. The PMC board is used in
embedded controllers. By using commercial Ethernet cable with
RJ-45 connector, you can easily set up the HSL slave modules as
close as possible to the sensor devices, reducing wiring effort.
Aside from the I/O modules, ADLINK provides the remote motion
control module with 4-axis pulse train type. The HSL network suits
a variety of machine-making applications as it integrates discrete I/
O, analog I/O, thermocouple module, and motion control. This
local network delivers rapid response time, time-deterministic
scanning and multiple-axis control. With PMC module, you may
also integrate the HSL network with embedded solution platforms.

The HSL system features:

X Distributed solution based on PC architecture or embedded

platform

X Convenient wiring for remote distributed I/O modules,

including discrete I/Os and analog I/Os

X Space-saving and discrete low-profile U-series form factor

X Hundreds of discrete I/O points

X Time-deterministic, fast scanning

X High-speed data acquisition

X Up to 120 axes of remote motion control with two HSL mas-

ter controller of master board

X Motion control features point table management and motion

Introducing HSL 1

1.1.1 Product Overview

The illustration shows the basic HSL system topology.

Figure 1-1: HSL topology

1.1.2 Product Highlights

High-speed performance

With scanning speed as high as 1000 points per ms, it takes
only 1.895 ms for an HSL master to scan all the discrete I/O
points of slave modules under 6 Mbps. For example, a distrib­uted control system with 63 slave I/O modules of HSL­DI16DO16-DB-NN with 2016 discrete I/O points can be
scanned or updated within 1.895 ms.

2 Introducing HSL

Time-deterministic scanning

The HSL master controller implements a deterministic time
period when scanning all slave I/O modules. The total scanning
cycle time is exactly proportional to the number of slave
indexes. At 6 Mbps, every 30.33 µs is added for another slave
index. For an HSL system with 30 discrete I/O slave modules
(where every discrete I/O module occupies one slave index),
the scanning time period is precisely 30 X 30.33 µs = 909.9 µs.
The scan time unit based on transmission rate is illustrated
below.

3 Mbps 6 Mbps 12 Mbps

Full Duplex 60.67 µs 30.33 µs 15.17 µs

Half Duplex 118 µs 59 µs 29.5 µs

Convenient wiring

The HSL master controller connects to all slave I/O modules
using Ethernet cables. This dramatically reduces the wiring
costs and effort. With Ethernet cables, hundreds or even thou­sands of I/O data can transmitted between the HSL master and
slave I/O modules. The HSL wiring is the easiest and most
cost-effective solution to date. For low profile series, you can
make the connection by direct wiring.

Multiple I/O points

The PCI-7853 offers one HSL master controller while the PCI­7854 offers two HSL master controllers. For maximum installa­tion, users can have eight PCI-7853 and PCI-7854 in one sys­tem. That means users can have 1512 slave indexes in HSL
network system. If choosing all connected modules as HSL­DI16DO16-DB-NN, a total of 24,192 digital input and 24,192
digital output points are supported. For embedded solution,
users can choose the PMC-7852/G.

Easy I/O expansion

Expanding I/O points for centralized configuration requires
more I/O boards and available PCI or ISA slots. Problems
occur when system needs more I/O points while there are no

Introducing HSL 3

available slot. In contrast with centralized configuration, the dis­tributed I/O configuration eliminates this limitation of a central­ized I/O configuration. With the HSL system, adding more I/O
points only requires one more slave I/O module and an Ether­net cable for communication link.

Self-diagnostic function

The HSL provides a self-diagnostic function that eliminates
communication failures. This function continuously monitors
the network status while a status register keeps the accumu­lated slave-no-response count for every individual slave I/O
module. Also, the HSL system features the CRC12 to eliminate
any communication error.

Modular design of slave I/O

ADLINK offers a variety of slave module types Including the
metal-cased M series, non-metal DB series, and U series for
compact systems. The M and DB series require a terminal
board for connection. Terminal boards act as carrier of slave I/
O module with wiring function. The Ethernet port and screw ter­minal on the terminal boards make it easier to replace I/O mod­ules without turning and wiring off the system.

Remote motion control compatibility

ADLINK also offers remote motion control solution based on
the HSL network Including the HSL-4XMO-CG-N/P and HSL­4XMO-CD-N/P that could connect up to four axes. The HSL­4XMO-CG-N/P features a general-type interface for use with
stepper or linear motors, while the HSL-4XMO-CD-N/P has a
D-sub interface. By using a transfer cable, you can connect to
specific servo amplifier. You can easily make a distributed con­trol application that includes discrete I/O, analog I/O, and
remote motion control.

Easy to program

Every HSL master card comes with 32 KB SRAM that carries
all the I/O status information of the HSL system. The ASIC on
the HSL master board communicates with all remote slave I/O

4 Introducing HSL

modules at fixed scanning period and keeps the most updated
I/O status information on the SRAM. You may read and write
the data in the 32 KB SRAM on HSL master card through the
PCI or PMC bus. You can easily read/write the most updated I/
O information and never worry with the HSL protocol.

1.1.3 HSL Applications

HSL as a Distributed PLC

The distributed PLC is an important system in the field of indus­try automation. Via communication modules, such as RS232,
RS485, PLC also performs distributed control. The traditional
architecture of distributed PLC application is shown in Figure

1.2. In this setup, the MPC (Monitoring PC) takes over as the
medium for data transmission from field to MIS.

RS-485

Figure 1-2: Traditional distributed PLC architecture

With the development of communication technology and popular­ity of networking, networking modules with Ethernet interface
became available. This improvement evolved as shown in the
architecture below. The medium character of the MPC was
replaced.

Introducing HSL 5

Figure 1-3: Networking PLC

PLCs that are capable of network communications are usually
very expansive. And since the PLC is not an open architecture,
only hardware vendors are capable of producing it.

6 Introducing HSL

The HSL distributed control architecture is illustrated in Figure 1.4.
With HSL, there is no need for an extra PC for Ethernet communi­cation. You may use only one IPC to control the entire system.

Figure 1-4: HSL as distributed PLC

Comparison between traditional PLC systems and HSL as distrib­uted PLC

X The MPC is replaced by a PC with HSL Master

X The HSL slave I/O module is replaced by a remote side

PLC

X The RS485 or RS232 cable is replaced by simple Ethernet

cable

X The protocol handling is replaced by simple memory read/

write.

HSL as Remote Time-deterministic DAQ

The HSL system, with high-speed performance and determin­istic time-deterministic scanning, is also applicable for remote
time-deterministic data acquisition.

Introducing HSL 7

The time-deterministic characteristic of an HSL system is an
important factor when implementing a DAQ application. With
an HSL system, all I/O data are refreshed in time-deterministic.
The sampling rate (or scan rate) is linearly dependent on the
number of slave indexed occupied, ranging from 91 µs (less
than three slave indexes) to 1.911 ms (63 slave indexes) under
6 Mbps. These two features go with HSL’s remote capability to
make it suitable for remote DAQ applications, especially when
time-deterministic is of utmost concern.

1.4 Technical Information

1.4.1 HSL Technology Introduction

Inside an HSL system, a single master controller communicates
with multi-slave through a command-response. The master con­troller sends commands to slave I/O modules for setting output
values and requesting input information. Every slave module
responds after receiving commands with address ID. The
responses may either be to set output according to the received
values or to reply requested input information to the master con­troller.

The illustration below shows the HSL working theory as regards
the setting of output values.

Figure 1-6: HSL technology brief -1

14 Introducing HSL

The teacher (master) sends message “ID.#, your output values
are XXX” to all students (slave I/O modules). Every student (with
ID.#) then sets its output channels according to the values heard.
The values that the teacher announced to the students are written
on the blackboard (RAM on master cards), and can be easily mod­ified.

The following illustration shows the working theory for gathering

input information.

Figure 1-7: HSL technology brief-2

Introducing HSL 15

The teacher (master) sends the message “ID.#, what is your latest
input status” to all students (slave I/O modules). Every student
(with ID.#) then gives his answer. The teacher writes the answers
on the blackboard (RAM on master cards). When someone (user’s
AP) wants to know the students’ answers, he refers to the black­board. All input information are saved in the memory.

These two procedures take turn and repeat on every slave mod­ule. After each cycle, each slave module sets its newest output
status and the master gathers all these information from the mem­ory. We simulate the polling communication cycle through a
teacher-student conversation:

Teacher: Student No. 1, your output vales are ##, what’s your lat­est input status?

Student No. 1: My input status is ##

Teacher writes the answer on the blackboard.

Teacher: Student No. 2, your output vales are ##, what’s your lat­est input status?

Student No. 2: My input status is ##

Teacher writes the answer on the blackboard.

Until…

Teacher: Student No. 63, your output vales are ##, what’s your lat­est input status?

Student No. 63: My input status is ##

Teacher writes the answer on the blackboard.

The polling cycle is now complete. The process repeats from Stu­dent No. 1.)
