| Digital I/O Modbus Modules - 15 Bit (1711M & 1712M) |
| Manufacturer: DGH |
| |
|
The D1700M digital I/O modules allow a host computer to control thousands of digital I/O points from one serial port when using RS-485 and repeaters in Modbus RTU format. When using RS-232 in Modbus format you are limited to one module. The status of inputs and outputs is communicated to the host in either Modbus RTU or DGH ASCII format using RS-232 or RS-485 serial communications.
All user selectable options (address, baud rate, etc.) are done through the communications port and are stored in nonvolatile EEPROM memory.
