Description
Configure the monitoring time from when the SECS/GEM communication software turns ON the
programmable controller CPU reception notification relay to when the programmable controller CPU
turns the relay OFF to confirm the handshake.
If the relay is ON after the specified time passes, the SECS/GEM communication software turns the
relay OFF.
For the operation of the PLC Response Monitoring Timer, refer to the following:
Page 89 PLC Response Monitoring Timer and Secondary Monitoring Timer
Configure the monitoring time from when a primary message is received, and the SECS/GEM
communication software turns ON the reception notification trigger relay to when the programmable
controller CPU turns the secondary message sending request trigger relay ON.
If the secondary message sending request trigger relay was not switched ON after the specified time
has past, the programmable controller CPU is notified if there are queued received messages. The
setting must be larger than the PLC Response Monitoring Timer.
For the operation of the Secondary Monitoring Timer, refer to the following:
Page 89 PLC Response Monitoring Timer and Secondary Monitoring Timer
Configure the delay time until a reconnection is attempted when a disconnection was detected.
Reconnection Delay After Line Disconnection is synchronized with the T5 timer setting.
Configure the number of reconnection attempts when a disconnection was detected.
Setting the maximum number of retries to "∞" (infinity) results in an infinite number of retries.

Configure the time from when a transaction is executed to when the next transaction is executed in the
course of a scenario that sequentially executes a series of transactions.
For details of scenario settings, refer to the following:
Page 114 Scenario Definition
When the ASCII data type is selected for SECS sending data, and the actual number of characters is
fewer than the predetermined number, specify the space filling method (NULL character or space
character).
When the sending data is configured as a fixed value, a number of characters that is fewer than the
number of SECS data sets is still valid.
Sending string data is referenced from the start control register. If there is a NULL character midway, a
character string from the start point to the NULL character is sent.
For operation and configuration of the number of multi-transaction queues, refer to the following:

Select this checkbox to switch the system into offline status upon detection of line disconnection.
After the status has switched to offline, the SECS/GEM communication software turns OFF the online
status of CA status notification.
When this checkbox is cleared, the online status continues even after detection of line disconnection.
