Relation between the Relay Status and Internal Switch
If the relay status of the internal switches is being displayed, an “S” will be displayed as the first
character. The next two characters show the number of the internal switch which corresponds to
the first batch of the display and range from 01 to 51. There are 60 internal switches.

Relation between the Relay Status and Alarm Output Relay (optional)
If the relay status of the alarm output relays is being displayed, a “0” will be displayed as the first
character. The next character shows the slot number at which the alarm module (/A4 option) or
DI/DO module (/R1 option) is connected. This number depends on the number of input channels
and whether or not the communication interface option is present.
The display of the relay status for the alarm output relays depends on the installed options and is
as follows.
• When the alarm module is installed (/A4 option), 10 indicators are reserved for “
■
” or “
■
”
display.
• When the DI/DO module is installed (/R1 option), 10 indicators are reserved for “
■
” or “
■
”
display, although the alarm output relays correspond to the first two indicators on the left,
whereas the other eight indicators are not used.
• When both the alarm module and the DI/DO module are connected, 20 indicators are reserved
for “
■
” or “
■
” display. The left 10 indicators are used for displaying the status of alarm output
relays for the alarm module, whereas the right 10 indicators are used for displaying the status of
the alarm output relays for the DI/DO module. In this case the first two indicators of the second
batch correspond to the alarm output relays, whereas the other eight are not used.
