16 Bit 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,
ăăDROP=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,
ăăDROP=d, SLOT=s, 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 input module
located in slot 4 of remote I/Odrop 3. This remote drop is connected to the
remote I/Osystem whose master is located in slot 15 in the master rack:
1020 RIODEF LEVEL% [ MASTER_SLOT=15, DROP=3,
ăăSLOT=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/Odrop 2. This remote drop is
connected to the remote I/Osystem whose master is located in slot 6 in the
master rack:
2050 RIODEF STARTPB@[ MASTER_SLOT=6, DROP=2,
ăăSLOT=7, REGISTER=0, BIT=9]
