DH-485 channel offers:
• configurable isolation via the 1747-AIC or 1761-NET-AIC interfaces.
• maximum network length of 1219 m (4000 ft).
• RS-485 electrical specifications.
• Belden 9842 or Belden 3106A cable connection between nodes (daisy-chain connection).
Processor Communication Options
The SLC 500 processors support several communication options.
The following sections describe the available physical connections and protocol options used by the SLC 500 processors.
Physical Connection Options
Ethernet (10/100Base-T) channel offers:
• 10/100 Mbps communication rate.
• ISO/IEC 8802-3STD 802.3 (RJ45) connector for 10/100Base-T media.
• TCP/IP communication protocol.
• built-in isolation.
Heat/Cool Minimum On-times
Words 6 and 8 for channel 1
These values determine the minimum cycle time after which loop
TPO bits will turn ON. They are used to allow contactors time to close
or pull in. If the contactor is energized for less than this value, the
contactor will not close, but the attempt will count as a cycle.
For example, suppose you set the TPO period for 10 seconds and the
minimum ON time to 1 second. Then if the module calculates a CV%
of 10% or less, the TPO bit for that zone will not turn ON.
Universal Remote I/O (RIO) Network
The strength and versatility of the Universal Remote I/O network comes from the breadth of products it supports.
In addition to 1746 I/O, the Universal Remote I/O network supports many Allen-Bradley and third-party devices.
Typical applications range from simple I/O links with controllers and I/O, to links with a wide variety of other types of devices.
You connect devices through remote I/O adapter modules or built-in remote I/O adapters.
Using the Universal RIO Network instead of direct-wiring a device over a long distance to a local I/O chassis reduces installation,
tart-up, and maintenance costs by placing the I/O closer to the sensors and actuators.
SLC 5/03, 5/04, and 5/05 processors support pass-thru which lets you configure RIO devices remotely from an Ethernet,
DH+, or DH-485/DF1 network, as well as block transfer instructions for faster reading and writing of I/O data.
