+86 15359408275ControlNet Communications Module · 1203 Drive Communication Platform
1203-CN1 is an electronic communication interface between a ControlNet network and one compatible SCANport device. A SCANport cable links the module to the host device.
The official manual shows one or two ControlNet cable taps depending on whether the network uses nonredundant or redundant media. The module transports command, reference, status and feedback data according to the configured host and network connection.
Commissioning requires the node address, network schedule, I/O mapping, host parameters, cable taps, termination and media redundancy to match the approved project. Verify the host-device firmware and complete 1203-CN1 hardware label before replacement.
The official 1203-CN1 user manual identifies catalog number 1203-CN1 as a ControlNet communications module for firmware 2.xxx. The module measures 3.92 x 2.69 x 3.54 in (99.5 x 68.4 x 90.0 mm), weighs 0.52 lb (236.7 g), operates from 0 to +55 °C, and draws 250 mA at 24 V DC.

1203-CN1 is a ControlNet communications module that exchanges command, reference, status and feedback data between one ControlNet network and one compatible SCANport device.
One 1203-CN1 connects to one compatible SCANport device through a SCANport cable, so it is not a multi-device controller or a general network switch.
1203-CN1 uses one network tap for nonredundant media or two taps for redundant media, and the installed topology, termination and cable routing must match the project design.
A 1203-CN1 replacement requires the node address, network schedule, I/O mapping, host parameters and media-redundancy settings to be recorded and restored correctly.
1203-CN1 is a communications interface rather than a standalone processor; operation depends on a compatible SCANport host, correct firmware and a commissioned ControlNet configuration.
A 1203-CN1 inquiry should include catalog number, firmware and hardware revision, quantity, host-device model, network topology, existing cable arrangement and clear nameplate photographs.
Send the complete 1203-CN1 catalog number, revision, quantity, destination and nameplate photo. Identification details will be checked before availability and lead time are confirmed.
