Variable Name Size/Type Description
Out -
WriteAcyclicData 1
Single-Bit
Boolean
This is the bit your control and sequencing logic will use to
trigger a message to tell the PROFIBUS Master to write
PROFIBUS DP-V1 Acyclic Data to a specific slave on the
network. Set this bit to one (1) whenever no other messages
are active and you want to send this acyclic message.
Out - SlaveAddress 1
8-bit Byte
Valid entries 0 - 125
Enter the node address of the slave device to which you wish
to send Acyclic Data.
Out - Slot 1
8-bit Byte
Valid entries 0 - n (where 'n' is the highest configured slot
number on the target slave address - depends on device
configuration.)
Enter the slot number on the target node to which you wish
to send the acyclic data.
Out - Index 1
8-bit Byte
See slave device manufacturer for valid entries.
This parameter is used to address the desired data block in
the target slave.
Out - LengthOfBytes 1
8-bit Byte
Valid entries: 1 - 200
Enter the number of acyclic data bytes you wish to write to
the target slave.
Out - IPAddress[ ] 4-element
16-bit
Integer Array
Each of the four integer elements holds one octet of the
message destination device's IP Address. For this
application, it will be the the ProLinx gateway's Ethernet port
address.
Out - WriteData 200-element
8-bit Byte
Array This array will be used to hold the acyclic data, in bytes, that
you wish to write to the target slave.
Out - RoutingRegister 1
16-bit
Integer
Default value for Quantum processors with built-in Ethernet
port is 254 (16#FE00 hex)

and DDTs (page 137)
In - ErrorDecode 1
8-bit Byte
If 'Fault' contains error code 0010h, more information can be
found here. For information on how to interpret these values,
refer to the slave device manufacturer's documentation or
the EN50170 (DP-V1) protocol specification.
In - Error1 1
8-bit Byte
If 'Fault' contains error code 0010h, more information can be
found here. For information on how to interpret these values,
refer to the slave device manufacturer's documentation or
the EN50170 (DP-V1) protocol specification.
In - Error2 1
8-bit Byte
If 'Fault' contains error code 0010h, more information can be
found here. For information on how to interpret these values,
refer to the slave device manufacturer's documentation or
the EN50170 (DP-V1) protocol specification.
In - Length 1
8-bit Byte
The value seen here specifies the number of valid data bytes
returned by the slave, if any.
In - ExtendedFault 1
16-bit
Integer
