6.4 Communication with PLC Manufactured by Mitsubishi Electric Corporation (MELSEC protocol)
6.4.1 When the MP2300S Acts as Slave (automatic receive function is used)
6-76
Caution
Communication using the automatic receive function is 1:1 communication.
Also, when “Communication Protocol Type: MELSEC” is used in communication with the MELSEC Q series, the MELSEC Q
series (master) side can read/write the holding register of the MP2300S (slave) using fixed buffer communication.
However, when the MP2300S acts as a slave, you cannot use the inter-CPU or random access communication, because of the
MELSEC specifications.
In addition, use the message receive function (MSG-RCV) when communicating with multiple remote devices.
Setting Example
The following figure illustrates one example of writing the contents of the data register (D00201 to D00300) of
MELSEC Q series (master) into the MP2300S (slave) holding register (MW00000 to MW00099).
The particular setup procedure is explained in the subsequent pages.
