56AMXN/B AutoMax DCSNet/RE RIO Module
Overview
This document is a user guide for the 56AMXN/B module, which allows
a Rockwell Automation ControlLogix backplane to communicate with an
AutoMax DCS network or an AutoMax Remote I/O network. The
module can act as a DCS master, a DCS slave or a remote I/O master.
For DCS master or slave operation, the 56AMXN/B uses a specific
RSLogix 5000 56AMXN module profile; for Remote I/O Master
operation, it uses the 1756-MODULE generic module profile.
As a DCS master, the module:
• Scans up to 55 slave drops
• Transmits 8 words of broadcast data
• Maintains standard DCS diagnostic counters
• Supports up to 8 scheduled connections with the ControlLogix
processor for drop data. Each scheduled connection supports up to 7
drops of input data from slaves to the master and 7 drops of output
data from the master to slaves. The connections can update at RPIs
from 3 to 750 ms.
• Supports a separate connection for broadcast data, at a fixed update
rate of 3 ms.
• Allows access to unmapped input, output and diagnostic data using
the Logix MSG instruction or using PCCC messages from RSLinx
and other HMIs
As a DCS slave, the module:
• Acts as any drop from 1 to 55, with drop depth from 1 to 55, with 32
words of input data and 32 words of output data per drop
• Receives 8 words of broadcast data from the master
• Monitors the input and output data on others drops on the network
• Maintains standard DCS diagnostic counters
• Supports up to 8 scheduled connections with the ControlLogix
processor. Each connection supports up to 7 drops of slave input
data from the module to the master and 7 drops of output data from
the slave to the master. The connections can update at RPIs from 3
to 750 ms.
As a Remote I/O master, the module:
• Scans up to 7 drops
