➀ Two of these may be Bulletin 1771 chassis.
➁ PLC 5/15 Series B Revision H or later have partial rack addressing. Earlier versions were limited to (3) devices.
➂ PLC 5/25 Series A Revision D or later have partial rack addressing. Earlier versions were limited to (7) devices.
With the Remote I/O version of the DL40, messages are normally triggered
from a PLC connected to the DL40. However, messages can also be triggered
via the Keyboard Port or the RS-485 Port.
DIP Switch 2-4 Enables or Disables Block Transfers.
