Introducing HSL 7
The HSL distributed control architecture is illustrated in Figure 1.4.
With HSL, there is no need for an extra PC for Ethernet communi-
cation. You may use only one IPC to control the entire system.

Comparison between traditional PLC systems and HSL as distrib-
uted 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 determin-
istic time-deterministic scanning, is also applicable for remote
time-deterministic data acquisition.
