Network WX Write (NETWX) (IB-702)
Network WX Write performs the WX instruction with built-in interlocking with all other
Network RX (NETRX) and Network WX (NETWX) IBoxes in your program to simplify
230 communications networking. It will
perform the WX on the specified Network
240
#, which corresponds to a specific unique
250-1
Network Configuration (NETCFG) at the
260
top of your program.
The Workspace parameter is an internal,
DS5 Used
private register used by this IBox and
N/A
HPP
MUST BE UNIQUE in this one
instruction and MUST NOT be used
anywhere else in your program.
Whenever this IBox has power, it will write
data from the master's V-memory buffer to
the specified slave starting with the given slave element, giving other Network RX and
Network WX IBoxes on that Network # a chance to execute.
For example, if you wish to read and write data continuously from 5 different slaves, you can
have all of these NETRX and NETWX instructions in ONE RUNG driven by SP1 (Always
On). They will execute round-robin style, automatically!
NETWX Parameters
• Network#: specifies the (CPU port's, DCM's, ECOM's) Network # defined by the NETCFG
instruction
• Workspace: specifies a V-memory location that will be used by the instruction
• Slave ID: specifies the slave PLC that will be targeted by the NETWX instruction
• From Master Element (Src): specifies the location in the master PLC where the data will be sourced
from
• Number of Bytes: specifies the number of bytes to write to the slave PLC
• To Slave Element (Dest): specifies the slave address the data will be written to
• Success: specifies a bit that will turn on once the request is completed successfully
• Error: specifies a bit that will turn on if the instruction is not successfully completed
