Ethernet/Ip Node Status Acquisition Instruction (Eipndst) - Panasonic FP7 User Manual

9.1.2 EtherNet/IP Node Status Acquisition Instruction (EIPNDST)

 Instruction format
R0
Note) A target unit for the instruction is specified with UNITSEL beforehand.
 Operation unit (i)
There is no operation unit.
 List of operands
Operand Description
S Specify the node number of an EtherNet/IP device whose status is acquired.
Specify the device address for setting the acquired status.
D1
Specify the device address for setting execution resutls of instructions.
D2

 Processing
• Stores the status fo the node number specified by S in the device specified by D1, and
stores the execution result in D2.
• Acquires the node status when the trigger (execution condition) turns on.
 Precautions during programming
• Call this instruction after X6B (EtherNet/IP preapration done) turns ON. If it is called before
X6B turns ON, the EtherNet/IP communication preparation incomplete error is returned.
• EIPNDST instruction cannot be executed simultaneously. A multiple execution error occurs.
The next execution must be executed after confirming the completion of an instruction.
