Description
Configure the relay to notify the programmable controller CPU when an online status (S1F1→S1F2)
was established between the host and equipment.
S1F1/F2 is treated as a special transaction.

Configure the relay to notify the programmable controller CPU when the line was disconnected between
the host and equipment.
The relay is ON immediately after the start-up of the SECS/GEM communication software. In the case
of HSMS, the relay is turned OFF at the time when TCP/IP connection completes and when Select.req
 Select.rsp is received.
For SECS- communication, the relay remains OFF after the SECS/GEM communication software
opens the port immediately after start-up. The relay cannot be turned ON even if the line was
disconnected. (A T2 protocol timeout error occurs when sending data.)
Do not use the relay as a disconnection detection condition of the Programmable Controller CPU.
Reconnection Retry Configure the relay to notify the programmable controller CPU during a line reconnection when the line
with the host was disconnected.
The reconnection retry relay is switched OFF when reconnection was completed or the Maximum
Number of Retries after Line Disconnection was exceeded.
For configuration of the Maximum Number of Retries after Line Disconnection, refer to the following:
Page 86 Control
To determine whether communication retries are being performed, refer to the following:
Page 101 Reconnection retry
Configure the relay to notify the programmable controller CPU when the SECS/GEM communication
software starts completely and enters a controllable state.
Note that the processing should be programmed so that the programmable controller CPU does not
detect errors before the CIM Control READY relay is turned ON.
Configure the relay to notify the programmable controller CPU when communication (S1F13→S1F14)
was established between the host and equipment.
Note that the determination of communication establishment depends on the setting that determines
whether S1F13 is used for the communication establishment sequence.
S1F13/F14 is treated as a special transaction.
For setting content, refer to the following:
Page 86 Control
Configure the relay to notify the programmable controller CPU when the sending message queue from
the SECS/GEM communication software reaches a value set for "Number Of Transaction Queues For
PLC Transmission".
The SECS/GEM communication software performs sending processing until the sending queue is full.
After that, however, even when sending is requested, sending fails, and the subsequent messages are
not sent.
Perform sending processing after clearing the sending queue full status.
Configure the relay to notify the programmable controller CPU when messages subject to spooling
have been spooled.
For details on the spooling function, refer to the following:
Page 123 Spool definition settings
 Configure the relay to notify the programmable controller CPU when the SECS/GEM communication
software is sending messages subject to spooling automatically.
*1
Trigger Keep Time
If there is no spool data when an S6F23 was received from the host, this relay is ON only for the time
configured by the trigger keep time.
For details on the spooling function, refer to the following:
Page 123 Spool definition settings
 Configure the relay to verify that the SECS/GEM communication software application is running from
the ladder program.
Detection period The SECS/GEM communication software follows the configured detection period and turns OFF the CA
Error Detection relay.
Configure the relay to notify of any error detection when the SECS/GEM communication software
accessed the memory card.
Configure the relay to notify the programmable controller CPU that the built-in battery of the MELSEC-Q
series SECS/GEM communication software pre-installed model module has died.
