AN-X-DCSNet2 Module Overview
The AN-X-DCSNet2 firmware runs on an AN-X AutoMax
communications module and connects a computer or other device to a
Reliance DCS network, using Ethernet. The module can act as a DCS
master or a DCS slave.
As a DCS master, the module:
• Scans up to 55 slave drops
• Transmits 8 words of broadcast data every 2.8 ms.
• Maintains standard DCS diagnostic counters
As a DCS slave, the module:
• Acts as any drop from 1 to 55, with drop depth from 1 to 55. It
supports 32 words of input data and 32 words of output data per drop
• Receives 8 words of broadcast data from the master every 2.8 ms.
• Monitors the input and output data on others drops on the network
• Maintains standard DCS diagnostic counters
You can use the AN-X-DCSNet module to communicate with an
AutoMax processor, using AutoMax Programming Executive 3.9A or
4.3A or above. Refer to page 18 for details. Note that AutoMax
programming software access is not supported under Windows Vista.
The AN-X-DCSNet2 firmware differs from the standard AN-X-DCSNet
firmware in that it supports up to 15 scheduled data connections to a
ControlLogix processor, whereas the standard firmware supports just one
scheduled connection.
Use the AN-X-DCSNet2 firmware in applications where you have a
large DCS network and want the data to update quickly.
The AN-X-DCSNet2 firmware does NOT support direct AN-X to AN-X
communication over Ethernet. If you need this function, use the standard
AN-X-DCSNet firmware.
The AN-X-DCSNet module supports exchanging scheduled data over
Ethernet with a ControlLogix processor, with RPIs from 5 to 750 ms.
Refer to page 22 for details.
The AN-X-DCSNet module has a web interface for configuration of
DCSNet operation and for monitoring operation and data. You can
communicate with the module using any standard web browser such as
Internet Explorer.
The module firmware can be updated over Ethernet using the Windows
utility supplied. Refer to page 61 for details.
