FUNCTIONS
4.3.1 Block guarantee of cyclic data per station
This function allows cyclic data to be ensured for each slave station.
Depending on the read/write timing, a block of cyclic data might be split into new and old
data in double-word (32-bit) units.
However, using this function ensures data consistency for each slave station.
(1) Applicable module
The following CC-Link module supports the block guarantee of cyclic data per station.
Remark
For new functions added to the C Controller module by functional upgrade, refer
to Appendix 7.
(2) Accessible devices
The following devices are accessible using the block guarantee of cyclic data per
station.
• RX on its own station
• RY on its own station
• Link registers (for sending) on its own station
• Link registers (for receiving) on its own station
• Buffer memory on its own station
POINT
This function is valid for the range of link refresh devices, which correspond to the
stations set with the parameters (Station information setting) of the CC-Link
master station.
For details of the link refresh devices (buffer memory) assigned to each station,
refer to "Slave station offset, size information" (buffer memory address: 3E0
H to
5DF
H) in the buffer memory list for the CC-Link module.
For details of "Slave station offset, size information", refer to the following.
