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 - MailBoxData Multi-variable
nested DDT For details, see Modbus DDT (page 98)
Out - TimeOut 1
16-bit Integer
Used to hold the amount of time in milliseconds to
wait for a response to the Modbus TCP/IP
command before assuming a communication error
has occurred and setting the In-MessageError
status bit.
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 -
LengthOfBytes 1
8-bit Byte
Valid entries: 1 - 200
Enter the number of acyclic data bytes you wish to write to
the target slave.
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 - Extended Fault 1
16-bit Integer

16-bit Integer
