Functional Devicenet Network Hardware Requirements - Control Techniques UD77 DeviceNet Startup Manual

Functional DeviceNet Network Hardware Requirements

Note: This guide describes a small DeviceNet network, or something larger that has been
reduced to two Unidrives and two UD77s.
Modular SLC 500 PLC, SLC 5/02 processor or better.
•
SLC 5/04 is recommended, unless additional Ethernet connectivity required.
•
SLC 5/05 is recommended if additional Ethernet connectivity is needed.
SLC 500 modular chassis
Needed to house the power supply, processor, scanner and I/O module(s). A 1746-A4 4-
slot-rack is described in this guide.
SLC 500 power supply
A 1746-P1 rated at 2.0A/0.46A (at 5 V/24V) is described in this guide.
At least one Discrete Input Module.
•
A "1746-IO12DC" combination input/output module is recommended for a small DeviceNet
network and is described, but not used, in this guide.
1747-SDN DeviceNet scanner module
PC-to-DeviceNet interface
This is required for configuring the scanner, and useful for commissioning the Unidrives.
• M/N 1770-KFD RS-232 interface is described in this guide. This interface can take its power
directly from the DeviceNet 24.0 VDC supply, so an optional 9.0 VDC supply is not required
unless isolating point-to-point taps are used with the interface.
Note that the interface cable that comes with this scanner can also be used as a 1747-CP3
cable into channel 0 of the processor to permit communication between the processor and
the PC.
•
M/N 1784-PCD PCMCIA interface is usable, but not described further.
•
M/N 1784-PCID PCI interface is also usable, but not described further.
Unidrive size 1 is recommended for evaluation, due to size. This includes Model Number(s)
UNI1401, UNI1402, UNI1403, UNI1404 or UNI1405. The Unidrive comes configured for
open loop operation as default, and this mode is assumed in this guide.
UD77 (UD70 with DeviceNet Interface) for each Unidrive.
The UD77TB (P/N 9290-56) is a small adapter PCB that provides a standard DeviceNet
open-style terminal connector and one is supplied with each UD77. A UD77 that is "up to
revision" contains the following subassemblies and firmware:
•
UD70 System file DNET.SYS (V2.6.0 is earliest, V2.7.6 or later is recommended)
•
UD70 Hardware UD70 issue 3
•
UD77 Firmware (V2.00)
•
UD77 Hardware UD77 Issue 2
DeviceNet Physical Media (the wire, power supply and terminating resistors)
