| The instrument is equipped with two communication ports : |
| - PC/PLC up to 32 instruments (max 99 with line repeaters) by ASCII Laumas protocol (compatible with W60000) or ModBus RTU. Optional protocols: Profibus DP, Ethernet/ModbusTCP, USB and Radio by appropriate converter. |
| - Slave Profibus DP port (instrument registered to Profibus organization - PNO), max 32 instruments without line repeaters; max 126 instruments with line repeaters. |
| - RS485 for connection to : |
| - PC/PLC up to 32 instruments (max 99 with line repeaters) by ASCII Laumas protocol (compatible with W60000) or ModBus RTU protocol. Optional Protocols: Ethernet/ModbusTCP, USB and Radio by appropriate converter. |
| - Remote display. |
| THEORETICAL CALIBRATION is performed via the keyboard. |
