MELSEC-A
AnCPU is suitable for simple systems up to large scale systems
- When used for large systems with A4UCPU, 4,096 I/O points and program memory capacity of 120k steps are supported.
- Systems of an even higher processing capacity can be built using A3A, A3U or A4UCPU instead.
- Systems can easily be expanded to a larger scale by utilizing the network, since A2U, A3U, A4UCPU are compatible with the MELSECECNET/10.
