eipAdapter

 Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Provides information about the current state of the Scanner connection.

Inputs

Input	Data Type	Range	Unit	Default	Description
N/A	N/A	N/A	N/A	N/A	This function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. block has no Inputs. It automatically refers to the adapter in the project.

Outputs

Output	Data Type	Range	Unit	Description
Run	BOOL	FALSE, TRUE	N/A	TRUE, if the EIP stack is running.
IOcnx	BOOL	FALSE, TRUE	N/A	TRUE, if an I/O connection is established with the Scanner.

Remarks

• This function block is used in a program The act of performing a sequence of instructions or commands. on the Adapter side.
• The servers (adapters) accessed by this block must be configured in the EtherNet IP EtherNet/IP™ is an open industrial application layer protocol for industrial automation applications. The EtherNet/IP application layer protocol is based on the CIP layer. Scanner fieldbus An industrial network system for real-time distributed control (e.g., CAN or PROFIBUS, Sercos®). It is a way of connecting instruments in a plant design. configuration.
• Only one explicit message (read or write) can be sent at one time to the same server.
  • If another message is pending you receive the error report 3 (busy) after calling the block to start a new exchange.
• Consider SerializeIn and SerializeOut functions for extracting data from the read buffer.

Example

Inst_eipAdapter();   // read the EtherNet Ethernet is a large, diverse family of frame-based computer networking technologies that operate at many speeds for local area networks (LANs)./IP adapter status

EIP_running := Inst_eipAdapter.Run;    // is it running?
EIP_connected := Inst_eipAdapter.IOCnx;   // and connected?
