12.1 Function List
Description
This function establishes a
connection and periodically perform
data communications between the
CC-Link IE TSN Plus module and
the EtherNet/IP device.
This function performs Explicit
message communications point-to-
point between the client (message
sending side) and the server
(message receiving and processing
side).
This function executes the service
specified by a command request
sent by the client and returns a
response.
Stop or restart of cyclic transmission is enabled individually for each connection with 'Class1 cyclic pause
specification' (Un\G7735808 to Un\G7735823).
Sets whether to stop or continue EtherNet/IP communications when RUN state is changed to STOP state
or a stop error occurs on a CPU module on which the CC-Link IE TSN Plus module is mounted.
■Class1 instance communications
Periodically performs data communications between EtherNet/IP
devices using an instance ID (number) for the connection. This
function is used for periodically communicating with an adapter.
■Class1 tag communications
Using a tag name (character string) for the connection, data
communications are periodically performed between EtherNet/IP
devices. This function is used for periodically communicating with
a scanner.
■UCMM message communications
Without establishing a connection between the CC-Link IE TSN
Plus module and the external device (server), message
communications are performed at any timing.
■Class3 message communications
By establishing a connection between the CC-Link IE TSN Plus
module and the external device (server), message
communications are performed periodically.
■UCMM tag communications
Without establishing a connection between the CC-Link IE TSN
Plus module and the external device (server), data is read and
written periodically for a tag through message communications.
■Class3 tag communications
By establishing a connection between the CC-Link IE TSN Plus
module and the external device (server), data is read and written
periodically for a tag through message communications.
■UCMM message communications
Without establishing a connection between the CC-Link IE TSN
Plus module and the external device (server), the command
request accepted from the client is processed and response data
is sent.
■Class3 message communications
By establishing a connection between the CC-Link IE TSN Plus
module and the external device (server), the command request
accepted from the client is processed and response data is sent.
■UCMM tag communications
Without establishing a connection between the CC-Link IE TSN
Plus module and the external device (server), data is read and
written for the set tag.
■Class3 tag communications
By establishing a connection between the CC-Link IE TSN Plus
module and the external device (server), data is read and written
for the set tag.
