(3) Considerations
• The write operation is not synchronized with the remote station controller scan
operation. If synchronization is necessary, applications must perform synchroni-
zation, such as transferring the data to separate registers at the start of the con-
troller scan.
• If the remote controller is PROSEC-T3H or T2N, write protection can be specified
for each register type on the local S controller by using the special coil settings. In
this case, a memory write protect error will occur. For more information about this,
refer to the PROSEC-T3H or T2N user's manual.
• When PC link transmission is used, if an application repeatedly transmits to a
nonexistent remote station at short intervals (less than 100 ms), an insufficient
resources error may occur. Applications should either stop transmitting to the non-
existent remote station or increase the interval between transmissions to prevent
this error.
