Ransburg Serial Node Adapter LECU4002_78553 - Manual (Page 34)

3. Assembly 78149-00:
This is reserved for the Cascading Digital
module (CCDG). The pneumatic connector is
unique to this module. Slots 0, 1, and 2 are
identical. I/O communication is via internal serial
bus (use cable to jumper to serial bus source)
or by discrete wiring to the module's terminal
strip on the rear.

DISCRETE WIRING
1. Serial Atomizer (SerAT) - must be paired with
Discrete I/O module (one DIO per SerAT). Con-
nections are made via the Discrete I/O cable.
2. Serial Digital (SerDG), Cascading Digital
(CCDG) - will accept 24 Vdc signals to 8 pin
terminal strips on rear of motherboard, behind
each slot. Module must be set via dipswitch for
this I/O configuration. The I/O for both Serial and
Cascading Digital is identical.
3. Serial Analog (SerAN) - will accept 0-10 Vdc or
4-20 mA signals to 8 pin terminal strips on rear of
motherboard, behind each slot. Module must be
set via dipswitch for this I/O configuration.
COMMUNICATION -
REMOTE I/O
The Allen-Bradley RIO via the Serial Node Adapter
can talk to any combination of up to 12 SerAT,
SerDG, CCDG, and SerAN modules via its local
CANBus. This requires Serial Node Adapter
Eprom Part #77128-04 (Version 2.02 or higher).
The local CANBus can consist of up to 4, 1/4 rack
motherboards connected together. Each mother-
board has an addressing switch, which must be
set to from 0 to 3, so that each slot has a unique
bus address. The PLC data mapping for the FLEX
mode is shown in the following figures.
