Description
Configure the line connection relay.
In case of an HSMS connection, the line is connected, and a Select request is sent by the line
connection relay trigger. In case of an SECS- connection, the port is opened.
The mode can be configured to specify an automatic connection attempt (AUTO) or a connection
attempt based on a request from the programmable controller CPU (MANUAL) during startup and upon
line disconnection detection.
If the startup connection mode and the reconnection mode were configured to "MANUAL", the line
connection relay only is the connection method.
Select the mode during start-up.
• AUTO
After SECS/GEM communication software start-up, TCP/IP and HSMS connections are attempted
automatically.
• MANUAL
After SECS/GEM communication software start-up, TCP/IP and HSMS connections are not attempted
until there is a request by the line connection trigger.
Select the mode during disconnection detection.
• AUTO
When a line disconnection was detected, such as a T6 Timer timeout, TCP/IP and HSMS connections
are attempted automatically.
If the disconnection was intentionally triggered by the disconnection trigger, TCP/IP and HSMS
connections are not attempted until there is a request by the line connection trigger.
• MANUAL
Even when a line disconnection was detected, TCP/IP and HSMS connections are not attempted until
there is a request by the line connection trigger.
Configure the line disconnection relay.
In case of an HSMS connection, the line is disconnected by the line connection relay trigger. In case of
an SECS- connection, the port is closed.
Configure the scenario interruption relay.
Scenario execution is interrupted by the trigger of the scenario interruption relay.
T9 dialog interruption is also possible.
Configure the dialog interruption relay.
Dialog execution is interrupted by the trigger of the dialog interruption relay.
T9 dialog interruption is also possible.
Configure the offline relay.
An offline transition is requested of the SECS/GEM communication software by the offline relay trigger.
When the "Switch Into Offline Status Upon Disconnection" checkbox is cleared at the [Control] tab, the
SECS/GEM communication software does not transition to offline other than by this request.
Nothing occurs when this request was detected in an already offline state.
The SECS/GEM communication software completes the transition to the offline state by this request.
When there is an offline procedure, have it complete before this relay is switched ON.
However, it is not necessary to wait for sending completion of an offline report message or secondary
message reception.
The SECS/GEM communication software switches OFF the offline relay immediately after detecting
that the offline relay is ON. The relay is switched OFF immediately even when there is already is an
offline state.
Completion of offline transition is checked by the "Online" relay.
Select this checkbox to configure a communication-disabled state following the offline transfer.
In a communication-disabled state, messages other than S1F13/F14 received from the host are
*3
discarded.
Furthermore, sending requests other than S1F13/14 are canceled.
Select this checkbox to close the TCP/IP port after the Separate procedure following the offline
*3
transition.
The reconnection procedure is not performed automatically. To start reconnection, use the line
connection relay.
The times that the Line Connection, Line Disconnection, Scenario Interruption, Dialog Interruption, and
Offline relays are held are monitored, and triggers are detected.
If the "Not Monitored" checkbox is selected, trigger processing is carried out without hold monitoring.
Configure the online-start relay to instruct a start in an online state.
To return to an online state after communication establishment (S1F13→F14) without performing an
online transfer (S1F1→F2) because, for example, a reset was performed while maintaining an online
state, set the online start relay to ON, and then start the SECS/GEM communication software.
Use the programmable controller CPU to determine advisability of the online start.
