When Using the Programmable Controller with a PGU
2.2.1
Signals related to the programmable controller
Signal communications between a PGU and a programmable controller are performed via the buffer
memory (BFM) in the PGU by using FROM/TO instructions. General BFM address allocations are
as shown below. (See pages 102 and 125 for details.)

MO to M127, Y440 to Y444, and data registers
70
to 77 are code numbers used for programs
in the PGU.
For example, BFM#2 bO is coded as Y440, and these two numbers indicate the same memory
area. Therefore, when BFM#2 bO is turned
ON
by the programmable controller, the instruction
of the
LD
Y440 instruction in the PGU also goes
ON.
