Variable Name Size/Type Description

Out -

WriteAcyclicData

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

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

For details, see Write Class 1 Acyclic Data Message

Structure (page 216)

In - Fault 1

16-bit Integer
