Description

N/A

This function block has no Inputs.

It automatically refers to the adapter in the project.

Outputs

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

Remarks

This function block is used in a program on the Adapter side.
The servers (adapters) accessed by this block must be configured in the EtherNet/IP Scanner fieldbus 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/IP adapter status

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