Communication cycle timing
The timing of the communication cycle is stored.
This area can be used in the inter-module synchronous interruption program (I44).
■ Normal speed (Un\G1277440)
"1" is stored at the timing of the start (first cycle in N cycles)/end (Nth cycle in N cycles) of the basic cycle interval during
normal speed cycle.
[b0]
• 1: Start (first cycle in N cycles)
• 0: Other than start
[bF]
• 1: End (Nth cycle in N cycles)
• 0: Other than end
■ Low speed (Un\G1277441)
"1" is stored at the timing of the start (first cycle in N cycles)/end (Nth cycle in N cycles) of the basic cycle interval during low
speed cycle.
[b0]
• 1: Start (first cycle in N cycles)
• 0: Other than start
[bF]
• 1: End (Nth cycle in N cycles)
• 0: Other than end
Cyclic data send/receive assurance information
■ Multiple cycle setting (low speed) (Un\G1277442)
The setting value of the multiple cycle setting (low speed) that ensures the cyclic data communications (send/receive) is
stored.
This value is stored when a device station exists for which, under "Basic Settings", "CC-Link IE TSN Class Setting" in
"Connection Device Information" is "CC-Link IE TSN Class A" and "Communication Period Setting" is "Low-Speed".
• 0: Calculation not performed
• 16, 32, 64, 128: Low speed cycle for basic cycle
■ Communication cycle interval (calculation value) (Un\G1277443)
The setting value of the communication cycle interval that ensures the cyclic data communications (send/receive) is stored.
This value is stored when a device station exists for which, under "Basic Settings", "CC-Link IE TSN Class Setting" in
"Connection Device Information" is "CC-Link IE TSN Class A" and "Communication Period Setting" is "Low-Speed".
• 0: Calculation not performed
• 125 to 4294967295: Communication cycle interval (unit: s)
