The Parallel Port terminal block at the back of the DL40 connects 20 parallel
input lines from the DL40 to the host PLC. Four strobe lines (MS0 – MS3)
indicate the type of data that is at the parallel port. The sixteen data lines (D0
through D15) provide the DL40 with its data input. The 12 volt power supply
provides a positive supply to drive up to 20 external DC Outputs. For more
information see Chapter 9.
