| Part Number: | UE20 | - | 1 | MCOM | - | 485 | / | 232 |
|---|---|---|---|---|---|---|---|---|
| Explanation: |
Platform UE20 - UE20 I/O platform |
Channels 1 - 1 serial communication channel |
Function MCOM - Modbus RTU master communication; this breakdown covers UE20-1MCOM-485/232 only |
Interface 485 - RS485 capability; retain the complete 485/232 suffix |
Interface 232 - RS232 capability; RS485 and RS232 are alternative interfaces for the single channel |
The UE20-1MCOM-485/232 provides one serial communication channel with RS485 or RS232 interfaces. It operates as a Modbus RTU master station and supports synchronization messages and communication timeout detection.
| Characteristic | UE20-1MCOM-485/232 |
|---|---|
| Communication channels | 1 |
| Physical interface | RS485 or RS232 |
| Protocol role | Modbus RTU master |
| Maximum RS485 network nodes | 32 |
| Selectable baud rates | 1200, 2400, 4800, 9600, 14400, 19200, 38400, 56000, 57600 and 115200baud |
