2800 & 2900 Series PLC Drivers
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:
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.
