You will need to identify a communication protocol available to both the PLC and the Keithley unit.The most likely protocol would be Modbus RTU. Many GE PLCs can be either Modbus RTU masters or slaves. If the Keithley can be a Modbus master, all you will need to do in the PLC is set up the port in hardware configuration. You will not need any additional ladder logic to support communications, although you may find it advantageous to group all the data exchanged with the Keithley in contiguous addresses. If the Keithley can only be a Modbus slave, you will need to use COMMREQ instructions in the PLC's ladder logic to control the data exchanges.
