DY 5020 + DX 5xx0
AutoLink Modbus TCP and PLC together as 2 different masters
• The combined use of one DY5020 and one DX5xx0 allows the simultaneous use of a Modbus TCP SCADA (e.g.: Ascon AutoLink) and a PLC
(PROFIBUS or DeviceNet or Modbus RTU).
• The SCADA and the PLC can also share the same Modbus RTU instrumentation.
