RMC100 Serial

RS-232/422/485 Communications for RMC Motion Controllers

Use the RMC Serial module as a cost-effective interface between the high-performance RMC motion controller and your process controller-whether a PC, PLC, or custom system.

The Serial module combines multiple communication protocols with optical isolation and software-selectable RS-232, RS-422, and RS-485 transceivers to form a versatile and industrial-hardened communication platform.

The RS-232 and RS-422 options provide full-duplex point-to-point communications, while RS-485 allows half-duplex multi-drop networking with up to 128 RMCs.

The Serial module is recommended in applications where the RMC's Event Step Table controls the majority of the process, and the communication is only needed for low-bandwidth monitoring or modifications to the process.

In applications where higher throughput is necessary, consider one of Delta's other communication modules.

Supported Serial Protocols

Serial ports are capable of communicating in a wide variety of protocols. The RMC Serial module currently supports the following protocols:

Allen-Bradley DF1
This protocol is supported by most Allen-Bradley PLCs and HMIs including the PLC-5, SLC 5/05, and ControlLogix. Allen-Bradley ControlLogix, SLC5/05, PLC-5, and SoftLogix 5
Modicon Modbus/RTU
This protocol is supported by most Modicon PLCs and a number of third party products.
No Protocol Mode
The RMC100 uses this custom protocol to communicate with the Mitsubishi FX2N.
