Variable Name Size/Type Description
Out - ReadcyclicData 1
Single-bit
Boolean
This is the bit your control and sequencing logic will use to
trigger a cyclic read message. Set this bit to one (1)
whenever no other messages are active and when you
want to update the PROFIBUS cyclic slave input data.
Out - RegisterCount 1
16-bit
integer
Will hold the total number of 16-bit register words of
PROFIBUS cyclic input data that need to be read. This
value will be the same as what you entered in the PCB
configuration for the [PROFIBUS
M ASTER DPV1] I NPUT
D ATA S IZE parameter
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 Quantum Communication Control and Data Buffer
Variables and DDTs (page 137)
In - ReadOperationActive 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP
message has been initiated and is being processed.
In - ReadOperationError 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP
response is not successfully received. When this bit is set,
it indicates your control and sequencing logic should retry
the command.
In -
ReadOperationSuccess 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.
