RMC100 Discrete I/0

Discrete I/O Communications for RMC100 Motion Controllers

The RMC100 DI/O module can be used to connect directly to switches in standalone applications or to connect to any PLC in applications that do not require large amounts of data transfer.

This module is also available as a Sensor DI/O module, which adds discrete I/O capabilities to the RMC with any communications option. The module consists of eight discrete outputs and eighteen discrete inputs. With an RMC100 CPU, the Discrete I/O module includes either an edge or quadrature counter.

Communication Modes

The communication modes are supported by the RMC100 only.

Input to Event Mode:
This mode can be used either with a PLC or switches. Each of the DI/O's first sixteen inputs can be used to trigger programmable event sequences on any number of axes on the RMC. The outputs can be configured to indicate in-position and error status or can be program controlled.
Parallel Event Mode:
This mode uses 9 inputs per axis for up to two axes to select any programmable event sequence. The outputs can be configured to indicate in-position and error status or can be program controlled.
Parallel Position Mode:
In this mode, the PLC sends 16-bit positions or open-loop drive values to the DI/O module, and at the same time, uses three other inputs to select the axis and motion profile. Outputs indicate in-position and error status.
Command Mode:
This flexible mode allows a PLC to send 32-bit commands to the RMC and request any 16-bit status word from the module. This includes actual position, drive, status bits, etc.
