Rockwell Automation 57C415 24V AC/DC Input Module - Manual (Page 32)

EĆ4
Single Register Reference
Use the following method to reference all 16 bits as a single register. Only one
statement is required in the configuration task for the entire module. The symbolic
name of the register should be as meaningful as possible:
nnnnn RIODEF SYMBOLIC_NAME%[ MASTER_SLOT=m, DROP=d, SLOT=s,
REGISTER=0]
Bit Reference
Use the following method to reference individual bits on the module. A maximum
of 16 statements can be included in the configuration task (one for each bit). The
symbolic name of each bit should be as meaningful as possible:
nnnnn RIODEF SYMBOLIC_NAME@[ MASTER_SLOT=m, DROP=d,
SLOT=s, REGISTER=0, BIT=b]
where:
nnnnn - BASIC statement number. This number may range from 1-32767.
SYMBOLIC_NAME% - A symbolic name chosen by the user and ending with
(%). This indicates an integer data type and all references will access the entire
module.
SYMBOLIC_NAME@ - A symbolic name chosen by the user and ending with
(@). This indicates a boolean data type and all references will access bit number
b" only.
MASTER_SLOT - Slot number that the master remote I/O module is plugged
into. This number may range from 0Ć15.
DROP - Drop number of the slave remote I/O module that is in the same rack as
the input module. This number may range from 1-7.
SLOT - Slot number that the module is plugged into. This number may range
from 0-15.
REGISTER - Always zero for this module.
BIT - Used with boolean data types only. Specifies the bit in the register that is
being referenced. This number may range from 0-15.
Examples Of Remote I/O Definitions
The following statement assigns the symbolic name LEVEL% to the input module
located in slot 4 of remote I/O drop 3. This remote drop is connected to the
remote I/O system whose master is located in slot 15 in the master rack:
1020 RIODEF LEVEL% [ MASTER_SLOT=15, DROP=3, .SLOT=4,
REGISTER=0]
The following statement assigns the symbolic name STARTPB@ to bit 9 on the
input module located in slot 7 of remote I/O drop 2. This remote drop is
connected to the remote I/O system whose master is located in slot 6 in the
master rack:
2050 RIODEF STARTPB@[ MASTER_SLOT=6, DROP=2, SLOT=7,
REGISTER=0, BIT=9]
