SETUP AND INSTALLATION
Prior to inserting the modules into the Module Mounting Unit
(MMU), there are four dipswitches that must be set (see Figure
for switch locations). Switch S1 has two functions depend-
ing on the use of the RIO.
S1 Mode Options
LOCAL MODE RMP (Remote Master Processor).
In local mode, S1 sets the slave address on the Expander Bus.
Valid addresses range between 0 and 63 (refer to Table
The slave address must be unique for redundant RIOs on the
MFP Expander Bus.
REMOTE MODE RSP (Remote Slave Processor).
In remote mode, S1 sets the node address. Valid addresses
range between 0 and 63 (refer to Table
). The node address
must be identical for redundant RIOs in the same remote node.
The maximum number of slaves on the Expander Bus is 64
and the maximum number of drops on the serial link is 16.
Address Switch Settings
Table
gives the switch settings that select module or node
addresses. The maximum expander bus and node address per-
mitted is 63. A switch position of 1 represents an open switch;
a switch position of 0 represents a closed switch.
