Variable Name Size/Type Description
Out - SetSlaveMode 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 change
the operating mode of a single slave or group of slaves. 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, 127
If you enter a value from 0 to 125, the acyclic message will
affect only the one slave device at this address.
If you enter a value of 127, the acyclic message will affect a
group of slaves, specified by the Out-GroupSelect
parameter.
Out - GroupSelect 1
8-bit Byte
For details on how to set this parameter, see Set Slave
Mode Message Structure (page 206)
Out -
CommandControl 1
8-bit Byte
For details on how the set this parameter, see Set Slave
Mode Message Structure (page 206)
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 -
SlaveModeActive 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP message
has been initiated and is being processed.
In - SlaveModeError 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 -
SlaveModeSuccess 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.
Note 1: It is only possible to send Sync and Freeze control acyclic messages when operating
mode is either "CLEAR" or "OPERATE".
Note 2: Not all slaves support this feature. Refer to the documentation for the actual slave for more
information.
