Access/attribute code
*1 Any device other than the above cannot be accessed. To access a bit device, specify 0 or a multiple of 16.
*2 When the target station is other than the CC-Link IE Controller Network module and CC-Link IE Field Network master/local module, refer
to the manual of the target station.
*3 None of D65536 and the subsequent extended data registers and of W10000 and the subsequent extended link registers are accepted.
The RIRD instruction can set the arrival monitoring time and the number of resends in the following link
special registers (SW).
• RIRD/RIWT instruction: Arrival monitoring time (SW0009)
• RIRD/RIWT instruction: Number of resends (SW000B)
When "RIRD/RIWT instruction: Number of resends (SW000B)" is set, the time taken for the RIRD instruction
to be completed with an error is determined by the following.
(RIRD/RIWT instruction: Number of r 1)

RIRD/RIWT instruction: Arrival monitoring time
However, if the target station (relay source station when addressed to another network) has been
disconnected at the time of RIRD instruction execution, no retry is executed. If the RIRD instruction is
completed with an error, re-execute the RIRD instruction after the target station (relay source station when
addressed to another network) returns.
If an error (error code: E504H) occurs in CC-Link IE Controller Network, a retry cannot be performed. Wait
until the instruction completes with an error, and execute the RIRD instruction again.
