1: Cannot be used if the executing station or target station is a safety CPU.
2: Writing to a safety CPU is not allowed from other stations.
3: When the target station is an A2UCPU(S1), A3UCPU, A4UCPU, A2ASCPU(S1), or
A2USCPU(S1), use the CPU module with the following version or later.
• A2UCPU(S1), A3UCPU, A4UCPU: Version AY (manufactured since July, 1995) or later
• A2ASCPU(S1), A2USCPU(S1): Version CP (manufactured since July, 1995) or later
