ECOM100 WX Network Write(ECWX) (IB-741)
ECOM100 WX Network Write performs the WX instruction with built-in interlocking with
all other ECOM100 RX (ECRX) and ECOM100 WX (ECWX) IBoxes in your program to
simplify communications networking. It will perform the WX on the specified ECOM100#’s
network, which corresponds to a specific unique ECOM100 Configuration (ECOM100) IBox
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 ECRX and ECWX instructions in ONE RUNG driven by SP1 (Always On).
They will execute round-robin style, automatically.
ECWX Parameters
• ECOM100#: this is a logical number associated with this specific ECOM100 module in the specified
slot. All other ECxxxx IBoxes that need to reference this ECOM100 module must reference this
logical number
• Workspace: specifies a V-memory location that will be used by the instruction
• Slave ID: specifies the slave ECOM(100) PLC that will be targeted by the ECWX instruction
• From Master Element (Src): specifies the location in the master ECOM100 PLC where the data will
be sourced from
• Number of Bytes: specifies the number of bytes to write to the slave ECOM(100) 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 ECOM100 RX and ECOM100 WX IBoxes
on that ECOM100# network a chance to execute.
