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
230
perform the WX on the specified
240
ECOM100#'s network, which corresponds to
250-1
a specific unique ECOM100 Configuration
260
(ECOM100) IBox at the top of your program.
The Workspace parameter is an internal,
DS5 Used
private register used by this IBox and MUST
N/A
HPP
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.
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
