Single Register Reference
Use the following method to reference the entire module 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,ă&

REGISTER=0]

Bit Reference
Use the following method to reference individual bits on the module. For the

entire 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,ă&

REGISTER=0, BIT=b]

where:
nnnnn Ć BASIC statement number. This number may range from 1Ć32767.
SYMBOLIC_NAME% Ć 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@ Ć 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 Ć Slot number that the master remote I/O module is plugged into.

This number may range from 0Ć15.
DROP Ć Drop number of the slave remote I/O module that is in the same rack as

the input module. This number may range from 1Ć7.
SLOT Ć Slot number that the module is plugged into. This number may range

from 0Ć15.
REGISTER Ć Always zero for this module.
BIT Ć Used with boolean data types only. Specifies the bit in the register that is

being referenced. This number may range from 0Ć15.

Examples Of Remote I/O Definitions
The following statement assigns the symbolic name LEVEL% to the output

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 STARTPL@ to bit 9 on the

output 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 STARTPL@[ MASTER_SLOT=6, DROP=2, SLOT=7,ă&

REGISTER=0, BIT=9]
