ControlNet Adapter Modules
The 1747-ACN15 and -ACNR15 modules enable up to three 1746 chassis of I/O
modules to produce/consume scheduled I/O on the ControlNet network. Both modules
are compatible with all 1746 discrete, analog, and specialty I/O, except those requiring
G-file configuration, such as the 1747-SN and 1747-BSN modules. The 1747-ACN15
and ACNR15 modules consume 0.9A at 5V dc.
The ControlNet Adapter Modules feature:
• optional media redundancy via dual BNC connectors (1747-ACNR15).
• individual connection to single modules or chassis connections to groups of
discrete modules.
• ability to upgrade firmware via ControlFlash.
The table below indicates with a “✓” which ControlNet controllers can communicate to
the 1747-ACN via scheduled messaging.
DeviceNet Network
The DeviceNet network is an open, low-level communication link that provides
connections between simple industrial devices like sensors and actuators to high-level
devices like controllers. Based on standard Controller Area Network (CAN) technology,
this open network offers inter-operability between like devices from multiple vendors. A
DeviceNet network reduces installation costs, startup/commissioning time, and system
or machine downtime.
The DeviceNet network provides:
• inter-operability – simple devices from multiple vendors that meet DeviceNet
standards are interchangeable.
• Common network - an open network provides common end-user solutions and
reduces the need to support a wide variety of device networks.
• Lower maintenance costs – replace devices without disrupting other devices.
