Receiving data
H-protocol
(Taskcode Communication)
Test mode
*1: It is required to operate dip switch setting when changing the operation mode.
*2: You need to make ladder diagram for error procedure at communication abnormal according to your
system.
Table 3.3 Functional Specification
- The tool for configuration is general Web browser.
- The configuration for IP address setting and Taskcode communication should be
done at IP address setting mode (*1).
- The ASR information and configuration for the area of sending/receiving should
be changed at IP address setting mode or normal operation mode (*1).
- IP address, routing information or configuration for taskcode communication can
be also done by Ladder diagram.
There are two sending functions.
1. Sending the data periodically called "Cyclic Sending".
2. Sending will be done at any time called "Event Sending".
- It is possible to change the sending functionality for every ASR connection.
- It is possible to use Web browser 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 ladder diagram to take care the operation for
sending. (*2)
The ladder diagram 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 ladder diagram to take care the operation for
receiving. (*2)
[Optional mode]
This should be specified when it is need to keep synchronizing the data of
destination area.
- It is required to prepare the ladder diagram 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 series taskcode (H-protocol).
- Internal loop back checking and External loop back checking are available.
- Peer to peer sending and receiving test is available.
