B2. Types of Relays and Registers
This module provides input relays and input/output data registers for accessing
the module from a CPU module. This chapter describes these relays and registers.
B2.1 Types of Relays
This module has 7 input relays for each loop and 4 system-wide input relays, but no
output relay. Table B2.1 (1/2) lists the loop-specific input relays. Table B2.1 (2/2) lists the
system-wide input relays. For details on each relay, refer to the text section indicated in
the “See Also” column.

TIP
A “

” mark in the “Interrupt” column denotes that the module allows an interrupt to be sent to the CPU
module when the input relay changes from 0 to 1. This allows a program on the CPU module to easily
detect, say, an alarm. For details on interrupt handling, read the instruction manual for the software used.
TIP
Input relays are refreshed at intervals defined by the input sampling period (100 or 200 ms) of the
module, except that the HOUT.R and COUT.R relays are refreshed at refreshing intervals for output
terminals (1/1000 of cycle time or 10 ms, whichever is longer).
An interrupt that is sent to the CPU module immediately after module startup may be
ignored if the CPU module is not ready to receive interrupts. Therefore, always check the
status of the module immediately after startup by reading the state of individual relays.
