Description
The RMS1-GR is a device designed for the acquisition and control of digital and analog inputs and outputs, by means of the Modbus Slave Serial ASCII/RTU. The serial communication is made by means of an RS232 or RS485 serial port. RS232 is via a 9-pin DB9 connector and the RS485 port is an RJ45 connector. Only one port can be used at any one time.
The equipment can have up to 16 opto-isolated or transistor inputs, up to 16 transistor or relay outputs and up to 6 analog inputs (0-10V or 4-20mA), all according to the different models of equipment. By means of a control device or Modbus Master software, it is possible to obtain the status of inputs and modify the status of outputs, individually or in groups.Two RMS1 unit would allow you to create I/O tunnels.
The RMS1-GR equipment features a configuration mode through a very intuitive Serial console that allows quick and simple configuration of the equipment. You gain access to the configuration menu within 7 seconds after powering up the equipment. It starts with a serial port configuration of 9600, 8, N, 1 and you gain access to the menu by entering “CFG” (not case sensitive). The equipment will remain in the configuration menu until a restart or the selection of the exit option in such menu. After this step, the equipment is ready to accept queries from any Modbus master.
