CompoBus/S Distributed I/O Functions (SRM1 Only) Section 1-8
Application Example
(Scheduled Interrupt
Mode)
In this example, an interrupt is generated every 4.0 ms (1.0 ms × 4) after input
00005 goes ON; the interrupts execute interrupt subroutine number 23.
1-8 CompoBus/S Distributed I/O Functions (SRM1 Only)
No. of Connected Nodes A maximum of either 16 or 32 CompoBus/S nodes may be connected.
The maximum no. of nodes can be set from a Programming Device by making
the following settings in DM 6603.
Note When changes are made to these settings, always turn the power off and on
again to make the new setting effective.
Slave Interrupts Input bits in IR 000 to IR 007 and output bits in IR 010 to IR 017 are used as
interrupts for CompoBus/S I/O Terminals. The CompoBus/S I/O Terminal
interrupts (IN 0 to 15 and OUT 0 to 15) are allocated as indicated in the follow-
ing table.
IN0 to IN15 are the node addresses for the Input Terminals and OUT0 to
OUT15 are the node addresses for the Output Terminals.
