Variable Name Size/Type Description
Out -
ReadAcyclicData 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 read
PROFIBUS DP-V1 Acyclic Data from 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 - 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 - SlaveAddress 1
8-bit Byte
Valid entries 0 - 125
Enter the node address of the slave device from which you
wish to receive 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 from which you
wish to retrieve 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 - Length 1
8-bit Byte
See slave device manufacturer for valid entries. Maximum
value is 200 bytes. See NOTE below.
This parameter specifies the number of bytes of the data
block that has to be read. If the slave data block length is
less than requested, the length of the response will be the
actual length of the data block. If the slave data block is
greater or equal, then the response will contain the same
amount of data.
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 - 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.
