Yaskawa, MP930 Memobus Interface
The MP930 interface uses RS-232 signal levels and is intended for point to point communication, i.e., only a single
peripheral device may be connected to the MP930 port. The OIT will be capable of reading and writing data to all MW
and Ml address locations. The 2800 and 2900 communicate using the T-Series Computer Link ASCII protocol.
ScreenMaker 2000 Port setup:
Node address: 1 through 247
Baud rate: 9600 bps or 19200 bps
Command Word Address: (MW Type), one word
Screen Trigger Address: (MW Type), two contiguous words
Byte format:
8 data bits, 1 stop bit, even parity
The following schematic shows the cable connections required between the OIT and the MP930 port 2 . This cable
is available from Quartech in a standard length of ten feet. Cables up to fifty feet in length may be ordered.
NOTES:
The OIT can directly address locations MW00000 through MW32767, and ML00000 through ML32767. Address type
MB is accessed using the Bit Status Field or Bit Status function key designation.
Up to four OITs can be connected to a single MP930 port using the Quartech Model 8517 Multiplexer.
