4 INTELLIGENT COMMUNICATION MODULE REPLACEMENT
4 - 1
(1) Replacement of intelligent communication modules AD51H-S3/A1SD51S
Point
(1) The serial communication module (QJ71C24N(-R2/R4)) can be used, depending on applications.
For details, refer to the TECHNICAL BULLETIN (FA-A-0059).
(2) Using the QA6
B as an extension base unit allows the AD51H-S3 to be used in the Q series
system.
Using the QA1S6
B allows the A1SD51S to be used in the Q series system.
Note that the QA6
B and the QA1S6 B cannot be used for the universal model QCPU (soon will
be supported).
If the QA6
B or the QA1S6B is required, consider replacing with the High Performance model
QCPU.
For replacement with the High Performance module QCPU, refer to "Transition from MELSEC-A/
QnA (Large Type) Series to Q Series Handbook (Fundamentals)".
Remarks
For how to replace the A1SD51S with the QD51(-R24), refer to Appendix 2.
