Single Register Reference
Use the following method to reference all 16 inputs as a single register. Only one
statement is necessary in the configuration task for the entire module. The
symbolic name of the register should be as meaningful as possible:
nnnnn IODEF SYMBOLIC_NAME%[ SLOT=s, REGISTER=0]
Bit Reference
Use the following method to reference individual inputs 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 IODEF SYMBOLIC_NAME@[ SLOT=s, REGISTER=0, BIT=b]
where:
nnnnn - BASIC statement number. This number may range from 1Ć32767.
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@ 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.
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

module located in slot 4:
1020 IODEF POSITION%[ SLOT=4, REGISTER=0]
The following statement assigns the symbolic name LIGHT to bit 9 on the input
module located in slot 7:
