1: If parameter setting has been made using the dedicated instructions, the data is
held. If parameter setting has been made using GX Works2, the data is clear
when the RY refresh device is set to Y, the data is cleared or held when the RY
refresh device is set to other than Y. (Refer to Section 8.2.5.)
2: When the RY refresh device is set to "Y" for the local station that has stopped,
only the receive area is cleared from the stopped local station; the receive area is
retained or cleared when the RY refresh device is set to other than Y. (Refer to
Section 8.2.5.)
Operation continues for the receive areas from other stations.
