Introducing HSL 21
Slave Index. A complete HSL system is composed of one master
and 1 to 63 slave indexes. The following diagram illustrates an
HSL system.
Figure 1-11: HSL system layout example-serial wiring
Every master circuit can support up to 32 slaves. However, since
the slave address is assigned by a 6-bit DIP-switch on the I/O
module’s termination board with the value ‘0’ reserved, the maxi-
mum number of slaves is 63, not 64. The slave I/O modules in an
HSL system must have different slave index. Though the slave
index may not necessarily continue from 1, continuous addressing
is more efficient. When an HSL system has only two slave mod-
ules addressed 1 and 63, the I/O refreshing rate is the same with
an HSL system with 63 slave modules addressed from 1 to 63.
Refer to Chapter 3: HSL Slave I/O Module for procedures on how
to set the addresses of slave I/O modules.
