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" in register r".
m =
Slot number that the master remote I/O module is
plugged into. This number may range from 0Ć15.
d =
Drop number for the slave remote I/O module that is in
the same rack as the input module. This number may
range from 1Ć7.
s =
Slot number that the module is plugged into. This
number may range from 0Ć15.
r =
Specifies the register that is being referenced. For long
integers this number must be either 0 or 3. For all other
references this number may range from 0Ć7.
b =
Used with boolean data 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 UPPER_LIMIT! to the
module located in slot 10 of remote I/O drop 7. This remote drop is connected to
the remote I/O system whose master is located in slot 9 in the master rack:
1000
RIODEF UPPER_LIMIT![MSTR_SLOT=9, DROP=7, SLOT=10, REG=3]
WARNING
IF YOU USE DOUBLE INTEGER VARIABLES IN THIS INSTANCE, YOU MUST
IMPLEMENT A SOFTWARE HANDSHAKE BETWEEN THE TRANSMITTER AND
THE RECEIVER TO ENSURE THAT BOTH THE LEAST SIGNIFICANT AND MOST
SIGNIFICANT 16 BITS HAVE BEEN TRANSMITTED BEFORE THEYARE READ BY
THE RECEIVING APPLICATION PROGRAM. FAILURE TO OBSERVE THIS
PRECAUTION COULD RESULT IN BODILYINJURYOR DAMAGE TO EQUIPMENT.
The following statement assigns the symbolic name COUNT% to register 1 on
the 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 COUNT%[MASTER_SLOT=15, DROP=3, SLOT=4, REGISTER=1]
2050
RIODEF PULSE_MULTIPLIER@[MASTER_SLOT=6,DROP=2, SLOT=7, ăăăăăăă&
REG=5, BIT=12]
