Standard UL/cUL
*1 The I/O device after the actual input points can be used as MELSECNET(/B), MELSECNET/MINI, or C.C-
Link.
*2 The maximum total memory that can be used for parameters, T/C set values, program capacity, file
registers, number of comments, sampling trace, and status latch is 32 k/64 k bytes. The memory capacity
is fixed. No expansion memory is available. Section 4.1.7 shows how to calculate the memory capacity.
