TRi, together with its technology partner: Kessler-Ellis Products, has developed a special driver for this low
cost, high resolution LCD touch panel to communicate with the TRiLOGI Super PLCs (Nano-10,
FMD, F-series and M-series) using the Native protocol.
Although the Super
PLCs' inherent support of MODBUS protocol means that any off-the-shelf MMI that supports
Modbus protocol can be used with the Super PLC, these are however limited to accessing the
data as 16-bit Modbus words only.
The KEP MMI's
support of the native protocol allows direct access to all the variables inside the Super
PLC without the need to refer to a Modbus memory map table, thereby simplifying the
development of Touch panel program and increasing its flexibility. |
