Compare Figure 1.2, and Figure 1.4:

The MPC (Monitor PC) is replace by PC with HSLink Master.

The remote side PLC is replaced by HSLink slave I/O modules

The RS485 or RS232 cable is replaced by simple Ethernet cable.

HSLink as Remote Real-time DAQ
HSLink system gets many beneficial features as described on sections
before. Among those features, two are worthy of being particularly notified.
l
High Speed
l
Real time
To implement a DAQ application, the real-time characteristic is the most
important issue. With HSLink system, all I/O data are time-deterministic
refreshed. The sampling rate (or scan rate) is linearly dependent on the
number of slave I/O module used, ranges from 90µs (less than 3 modules)
to 2 ms (63 modules). These two features with HSLink’s born-nature
remoteness make HSLink very suitable for remote DAQ applications,
especially when real-time is concerned.
