Relay Numbers

External input relays (X), External output relays (Y), Internal relays (R), Link relays
(L) and Pulse relays (P)
Since these relays are handled in units of 16 points, they are expressed as a
combination of decimal and hexadecimal numbers as shown below.
1,2,3...
Decimal number
Hexadecimal number
The maximum value that can be selected varies with each relay.
Example: External input relay (X)
X0, X1
X10, X11
X20, X21

Timers (T) and Counters (C)
The addresses for timer contacts (T) and counter contacts (C) are correspond to the
timer and counter instruction numbers and expressed in decimals as shown below.
Example: FP2
Decimal number
T0, T1
C1000, C1001
Note
Counters and timers share the same area. The division of the
area can be changed with system register 5. (The table and
example are when settings are the default values.)
Error alarm relays (E) (FP2SH/FP10SH only)
The addresses for error alarm relays (E) are represented in only decimals.
E0, E1 . . . . . . . . E2047
