REMARK
1: For the timer, retentive timer, and counter, bit devices are used for the "contact"
and the "coil", and the word device is used for the "present value".
2: The actual number of usable points varies according to the intelligent/special
function module.
For details regarding the buffer memory's "number of points", refer to the
Intelligent/Special Function Module Manual.
3: Inputs, outputs, step relays, link special relays, link special registers remain at
their default values, which cannot be changed.
