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,

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,

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,
