4. Sequencing Using the Delcos Protocol
This section describes how to connect and configure machines for sequencing using the Delcos protocol.
This protocol is also used for machines connected to a Connect 12 system controller.
4.1 Wiring Connections
-
Wiring connections for the Delcos sequencing protocol are shown in Figure 18 below. Daisy chain
the RS485 connections from the master machine to the first slave machine then second slave
machine, etc. for each machine in the sequenced group. The Delcos RS485 connections are
located on the IO Module at X02 in the control cabinet. Depending on the machine configuration,
RS485-2 at X03 on the IO module can also be used, if populated. Setup and configuration for
RS485-2 is identical to RS485-1.
Figure 18: Delcos RS485 Communication Wiring Schematic
Figure 19 shows the hardware Interface for the RS485 Connections on the IO Module as shown in
the wiring diagram in Figure 18. Make sure that the machines at the end of the sequencing network
have the RS485
terminating resistor DIP switch in the ‘ON’ position. The location of the DIP switch
is highlighted below in Figure 19.
