Parameters	Memory area code (command): The data area to read.

Beginning address (command): The address of the first word/bit/flag to read from memory. Specify 00 (Hex) for the 3rd byte.

No. of items (command): The number of items to be read. Specify 0000 to 03E7 (Hex) (0 to 999 decimal). The command can be completed normally even if zero items are specified.

Data (response): The data from the specified words is returned in sequence starting from the beginning address. PVs for timers and counters are returned as BCD. The required number of bytes in total is calculated as follows:

No. of bytes required by each item ⋅ No. of items
