Is it possible to have rs232 connection to peripheral port of omron cpm1 plc to be used for uploading and downloading of program and if so does anyone have wiring diagram .
thanks Robert
The CPM1/CPM1A only has a peripheral port connector.
The CPM1-CIF01 is an adapter unit, DB9 on the front with a short cord with the peripheral connector to plug into the plc.
So ,if it is only an adaptor does anyone have the pinout of this unit going back to the peripheral plug like a one to one connection from db9 to the peripheral plug for omron cpm1 plc ?
