Appendix-2 About Use of Programs from Previous Modules

Here, use of programs created for A1SE51S or AD51H-S3 is explained.
In the QD51 (-R24), there are no switches for mode settings or console and other
settings as in the previous modules (A1SD51S, etc.).
When the QD51 (-R24) is used, be sure to set the mode settings and console and
other settings in the GX Developer parameter setting screen shown below.

POINT
Usable channels are as shown below.
CH. 1 (RS-232)
CH. 2 (RS-232)
CH. 3 (RS-422/RS-485)
CH. 4 (Parallel)
(a) Use in the QD51
If used in the QD51, there is no CH. 3 (RS-422/485) or CH. 4 interface in
the QD51, so they cannot be used.
As for CH. 3 (RS-422/485), correct the BASIC program to another channel
or use the QD51 -R24.
CH. 4 (Parallel) cannot be used.
(b) Use in the QD51 (-R24)
If used in the QD51, there is no CH. 2 (RS-232) or CH. 4 interface in the
QD51, so they cannot be used.
As for CH. 2 (RS-232), correct the BASIC program to another channel or
use the QD51.
CH. 4 (Parallel) cannot be used.
AD51H-S3 A1SD51S
: Can be used
MELSEC-Q
