Serial Communications
Section 8-3
CP1L-EL/EM is set as the link master, so CIO 3000 to CIO 3007 are its write
area. Any data written to these words with the OUT or MOV instructions will
be automatically transferred to LR 00 to LR 07 in the CPM2A. The CPM2A will
use these words as its read area.
CIO 3008 to 3015 are the read area of the CP1L-EL/EM. The contents of LR 08
to LR 15 in the CPM2A will automatically be transferred to CIO 3008 to 3015 in
the CP1L-EL/EM. The words in the PLC’s read area cannot be written using the
OUT, MOV, or any other write instructions.
8-3-7
1:N NT Links
In the CP Series, communications are possible with PTs (Programmable Ter-
minals) using NT Links in 1:N mode.
Note
Communications are not possible using the 1:1-mode NT Link protocol.
High-speed NT Links are possible in addition to the previous standard NT
Links by using the PT system menu and the following PLC Setup. High-speed
NT Links are possible, however, only with NS-series PTs or with the NT31(C)-
V2 or NT631(C)-V2 PTs.
