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
communications networking. It will perform the WX on the specified Network #, which
corresponds to a specific unique Network Configuration (NETCFG) at the top of your
program.
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

The Workspace parameter is an internal,
private register used by this IBox and 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.
