*1 To perform online change, check the "Permit" checkbox under "RUN write setting".
*2 Devices such as TS, TC, SS, SC, CS, and CC cannot be specified in units of words. For the monitor registration, an
error (4032 ) occurs during the monitor operation.
H
*3 Random read and monitor registration cannot be executed to the CPU module during the conditional monitoring.
*4 Do not execute monitor registration from multiple external devices. If executed, the last monitor registration becomes
valid.
*5 Set the number of processing points within the range of the following calculation formula.
(number of word access points) × 12 + (number of double word access points) × 14  960
•
One point of a bit device corresponds to 16 bits for word access or to 32 bits for double word access.
•
One point of a word device corresponds to one word for word access or to two words for double word access.
