Dfb_Eip_Exp Function Block; Parameters - Delta AHCPU560-EN2 Series Operation Manual

Et herNet / I P O perat i on Manual
All connections in EtherNet/IP can be divided into explicit messaging connections and implicit (or I/O) messaging
connections. Explicit messaging uses TCP/IP and request/response communications procedure or client/server
connection, requiring that the memory location of the information to be sent to the client be defined in the instruction itself.
Implicit messaging uses UDP/IP and is when a server sends information from predefined memory locations to a client at a
given interval, using a requested packet interval (RPI) parameter to specify the rate at which data updates.

5.1. DFB_EIP_EXP Function Block

See the DFB_EIP_EXP function block below. Refer to the section 9.8 for objects that are supported by AH10EN-5A. For
using slaves via the AH10EN-5A, refer to the slave manual for related information on Objects.
When the AH10EN-5A acts as scanners for EtherNet/IP, users can use the function block DFB_EIP_EXP to read/write the
objects of the adapters. When the EIP builder uses Objects as its parameters, every Object has various parameters.
The parameter unit is Attribute and the read/write path is ClassInstanceAttribute.

5.1.1 Parameters

The meaning of each parameter in the function blocks are stated below.
Name
Execute (Execution Bit)
BID (Backplane number)
SID (Slot number)
PID (Port number)
IP1 (IP address 1)
IP2 (IP address 2)
5 - 2
When the execution bit turns from Off to On, the function block will be
executed and will send out an explicit message. When the operation is
complete, the Done bit will be On. While an error occurs, an Error bit will
be On, and an error code will be shown in the ERRCode.
The backplane number of the scanner module: 1
The slot number of the scanner module:0-11
Assigned Ethernet Port for the scanner module
This parameter is used to assign the first two IP addresses of the
adapter for the assigned scanner to read/write.
Example: IP = 192.168.1.5, IP1 will be written as 16#C0A8.
This parameter is used to assign the last two IP addresses of the
adapter for the assigned scanner to read/write.
Example: IP = 192.168.1.5, IP2 will be written as 16#0105.
