Communication period setting value (protocol version 2.0)
■Communication cycle interval (calculation value) (Un\G1277444)
Stores the communication cycle intervals that are calculated by the number of slave stations and the number of link device
points set in "Network Configuration Settings" under "Basic Settings".
Stores the communication cycle interval of protocol version 2.0 regardless of the setting value of 'Protocol setting'
(Un\G1294018). When 'Protocol setting' (Un\G1294018) is set to '1: Protocol version 1.0 fixed', if devices supporting protocol
version 1.0 and devices supporting protocol version 2.0 are mixed, refer to the value in this buffer memory, and set the
appropriate value to "Communication Period Interval Setting" in "Communication Period Setting" under "Basic Settings".
• 125 or greater: Communication cycle intervals (unit: s)
■Cyclic transmission time (calculation value) (Un\G1277445)
Stores the cyclic transmission times that are calculated by the number of slave stations and the number of link device points
set in "Network Configuration Settings" under "Basic Settings".
Stores the cyclic transmission times of protocol version 2.0 regardless of the setting value of 'Protocol setting' (Un\G1294018).
When 'Protocol setting' (Un\G1294018) is set to '1: Protocol version 1.0 fixed', if devices supporting protocol version 1.0 and
devices supporting protocol version 2.0 are mixed, refer to the value in this buffer memory, and set the appropriate value to
"Communication Period Interval Setting" in "Communication Period Setting" under "Basic Settings".
• 1 or greater: Cyclic transmission time (unit: s)
■Transient transmission time (calculation value) (Un\G1277446)
Stores the transient transmission times that are calculated by the number of slave stations and the number of link device
points set in "Network Configuration Settings" under "Basic Settings".
Stores the transient transmission times of protocol version 2.0 regardless of the setting value of 'Protocol setting'
(Un\G1294018). When 'Protocol setting' (Un\G1294018) is set to '1: Protocol version 1.0 fixed', if devices supporting protocol
version 1.0 and devices supporting protocol version 2.0 are mixed, refer to the value in this buffer memory, and set the
appropriate value to "Communication Period Interval Setting" in "Communication Period Setting" under "Basic Settings".
• 1 or greater: Transient transmission time (unit: s)
