Variable Name Size/Type Description

Out -
WriteCyclicData

1

Single-bit
Boolean

This is the bit your control and sequencing logic will use to
trigger a cyclic write message. Set this bit to one (1) whenever
no other messages are active and when you want to send
PROFIBUS cyclic slave output data.

Out -

RegisterCount

1

16-bit integer

Will hold the total number of 16-bit register words of
PROFIBUS cyclic output data that need to be written. This
value will be the same as what you entered in the PCB
configuration for the [PROFIBUS

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 - Routing
Register

1

16-bit Integer

Default value for Quantum processors with built-in Ethernet
port is 254 (16#FE00 hex)

For details, see "MBP_MSTR, Ethernet (Quantum) - Control
Block for TCP/IP Ethernet" in Quantum Help Files, or

In -
WriteOperation
Active

1

Single-bit
Boolean

The DFB will set this bit when the Modbus TCP/IP message
has been initiated and is being processed.

In -
WriteOperation
Error

1

Single-bit
Boolean

The DFB will set this bit when the Modbus TCP/IP response is
successfully received and the PROFIBUS cyclic input data
variables have been updated.

In -
WriteOperation
Success

1

Single-bit
Boolean

The DFB will set this bit when the Modbus TCP/IP response is
successfully received and the PROFIBUS cyclic output data
variables have been updated.
