(Taskcode Communication)
Test mode
*1: It is required to operate dipswitch setting when changing the operation mode.
*2: You need to make the user program for error procedure at communication abnormal according to your
system.
Table 3.3 Functional Specifications
- Set up EH-ETH2's Communication parameter with the dedicated software
"EH-ETH2 Configurator".
- The configuration for IP address setting and Taskcode communication should be
done at Configuration mode.
- The ASR information should be changed at Configuration mode or normal
(*1)
operation mode.
- IP address or configuration for taskcode communication can be also done by the
user program.
There are two sending functions.
1. "Cyclic Sending" is periodically-sending function.
2. "Event Sending" is voluntarily-sending function.
- It is possible to change the sending functionality for every ASR connection.
- It is possible to use EH-ETH2 Configurator to change function of sending, to
specify the attention of sending data and to specify the source of sending area.
This should be specified when it is no need to keep synchronizing the data of
source area.
- It is possible to send the data with only specifying the attention of destination,
area of source and time of cyclic.
- There is no need to prepare the user program to take care the operation for
(*2)
sending.
The user program is required to control the everything related with sending
operation.
There are two types Receiving mode. One is Normal mode. The other is Optional
mode.
[Normal mode]
This should be specified when it is no need to keep synchronizing the data of
destination area.
- It is possible to receive the data into destination area with only specifying the
attention of source and area of destination.
- There is no need to prepare the user program to take care the operation for
(*2)
receiving.
[Optional mode]
This should be specified when it is need to keep synchronizing the data of
destination area.
- It is required to prepare the user program to take care the receiving data into the
destination area.
- It is possible to specify TCP/IP or UDP/IP.
- It is possible to communicate using H/EH series taskcode (H-protocol).
- Peer to peer sending and receiving test is available.
