The Romod module family is a set of romutec® local override/indication devices (LO/ID) for mounting on DIN rails. It consists of various types of I/O modules. The connection to the MODBus master device is done via a RS485 connection. The communication takes place via MODBus RTU.
Each module has its own RS485 bus interface, therefore no gateway module is required. The address is set by means of an 8-pin dip switch. The available range of addresses is 0 ... 255.
The local override/indication devices operate as slave modules with any MODBus master. The baud rate of the protocol will be automatically detected when receiving several telegrams.
