Variable Name Size/Type Description
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 -
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 -

For details on how the set this parameter, see Set Slave
Mode Message Structure (page 206)
Out - MailBoxData Multi-variable

In - MessageDone 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP response
is successfully received.
In - MessageError 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.
