The Head number of the data sent to the RMC100 is designated by (S2) in the BIDOUT
instruction. The data must be according to the following format:
Each box is a 16-bit word.
Count: The number of registers to read.

format. See the PROFIBUS Register Map topic in the RMCWin help for details.
After receiving the request, the RMC100 will return the requested data. The BIDIN instruction is

read from the QJ71C24 buffer. To read the returned data, (D1) in the BIDIN instruction indicates
the head number of the device to store the data in.
