Data type Description
IN Input BOOL If Rising Edge (IN turns from FALSE to TRUE), start the function block with the
precondition that the last operation has been completed.
CtrlCfg Input CIPCONTROLCFG Function block execution control configuration.
See CIPCONTROLCFG data type on page 177.
SymbolicCfg Input CIPSYMBOLICCFG Information for the symbol to Read/Write.
See CIPSYMBOLICCFG data type on page 187.
TargetCfg Input CIPTARGETCFG Target device configuration.
See CIPTARGETCFG data type on page 180.
Data Input USINT[490] Read command stores the data returned from the server.
Write command buffers the data to be sent to the server.
When a MSG is triggered or retriggered, Data is cleared for the MSG Read
command.
See Supported Data Packet Size for CIP Serial Function
Tip: Refer to 2080-qs002_-en-e.pdf
Q Output BOOL Outputs of this instruction are updated asynchronously from the program scan.
Output Q cannot be used to re-trigger the instruction since IN is edge triggered.
FALSE - The function block is not done.
TRUE - The function block is done.
Status Output CIPSTATUS Function block execution status
When a MSG is triggered, or re-triggered, all elements inside Status are reset.
See CIPSTATUS data type on page 178.
DataLength Output UDINT Number of data bytes Read/Written.
When a MSG is triggered or retriggered, DataLength is reset to 0 for MSG Read
command.
