*1 Can be configured for only the MELSEC-Q series SECS/GEM communication software pre-installed model module.
*2 SECS/GEM communication software uses the time of the SECS/GEM communication software pre-installed model module in log data.
As a result, when the logs are viewed, the order of data may appear different from actual data transmission and reception, in accordance
with the time changes.
*3 Can be configured only by a non-GEM version.
Description
*1
Configure the shared memory synchronization adjustment timer.
Sometimes adjustments are required when shared memory is assigned to a trigger relay.
When shared memory is assigned, the SECS/GEM communication software controls the relay by
handshaking and then verifies that the prescribed relay status has been updated by a refresh of the multiple
CPUs in accordance with the value of this simultaneous adjustment timer.
When ladder program processing requires time, a change in the relay status is not detected even if the SECS/
GEM communication software is delayed by the configured time, resulting in status inconsistency.
At this time, adjust the timer value, taking into consideration ladder program scan processing.
Select this checkbox to configure the time of the MELSEC-Q series SECS/GEM communication software pre-
installed model module when an S2F31 or S2F18 was received.
The SECS/GEM communication software uses an S2F18 or S2F31 for reserved transactions and, upon
receipt of time data from the host, replaces the time of the MELSEC-Q series SECS/GEM communication
software pre-installed model module.
However, it synchronizes with the time of CPU No. 1 automatically when Multiple CPU Setting has been
configured.
For details on S2F18 and S2F31 transactions, refer to the following:

Select this checkbox to configure the time of the MELSEC iQ-R series SECS/GEM communication software
pre-installed model module when an S2F31 or S2F18 is received.
S2F18 and S2F31 do not need to be defined by users as they are regarded as reserved transactions.
When enabling this function, the time synchronization function between the module and a CPU module is
disabled.
For details on S2F18 and S2F31 transactions, refer to the following:

Select this checkbox to clear the messages accumulated in the SECS/GEM communication software sending
queue when a T3 timeout has occurred.
Select this checkbox to clear the messages accumulated in the SECS/GEM communication software sending
queue when a T9 timeout has occurred.
Select this checkbox to clear the messages accumulated in the SECS/GEM communication software sending
queue when a dialog violation has occurred.
Select this checkbox to use the SECS/GEM communication software as a host to communicate with the
equipment.
When the SECS/GEM communication software will be installed on the equipment, clear the checkboxes of
HOST mode and GATEWAY mode.
Select this checkbox to use the SECS/GEM communication software as a gateway to intermediate messages.
When the SECS/GEM communication software will be installed on the equipment, clear the checkboxes of
HOST mode and GATEWAY mode.
If a register is assigned in this setting, the number of messages currently in queue is output to the specified
register.
When the checkbox of "Maximum Queue Counts" is selected, a value set for "Number Of Transaction Queues
For PLC Transmission" is stored in the configured register No. + 1 word.
Configure the data type when storing the Communication disconnection occurrence time.
If "DATE-Q" or "DATE-A" is selected for the storage format, the time is stored in binary.
For an example of a value stored to a register, refer to the following:
Page 96 Register storage formats
Configure the register to store the time when the communication state changed from "COMMUNICATING" to
"NOT COMMUNICATING".
The updating of this register is synchronized with the switching of the CA state notification relay and
Communication established relay from ON to OFF.
This is normally when a line disconnection detection and Communication failure (sending error) occur, but "T3
timeout" and "Set communication as disconnected by receipt of an abort of message subject to spooling" may
also be included in the conditions depending on the settings of the [Control] tab.
File output can be stopped to prevent file corruption before a reset of a SECS/GEM communication software
pre-installed model module.
When the file output stop relay is ON, it operates as though the Mode switch of the SECS/GEM
communication software pre-installed model module is OFF.
