ACS355 with MODBUS TCP¶
Used drive Communication Module: FENA-x1:
Question: How many values should be exchanged?
- only status word, actual speed, control word and speed reference:
- communication profile in drive parameters: ABB Drives classic
- communication Function Block in AC500 program: Use ACS_COM_MOD_TCP ACS_COM_MOD_TCP Communication for ACS / DCS Drives via MODBUS TCP, if PLC firmware is less than V2.4, else use ACS_COM_MOD_TCPx ACS_COM_MOD_TCPx Communication for ACS / DCS Drives via MODBUS TCP
- control Function Block in AC500 program: ACS3XX_DRIVES_CTRL_BASIC ACS3XX_DRIVES_CTRL_BASIC Basic Control of ACS3XX / ACX550 Drives with ABB Drives Profile, Including Scaling of Actual and Reference Values
- scaling: the scaling is included in the ACS3XX_DRIVES_CTRL_BASIC ACS3XX_DRIVES_CTRL_BASIC Basic Control of ACS3XX / ACX550 Drives with ABB Drives Profile, Including Scaling of Actual and Reference Values Function Block
- status word, actual value1 (speed), actual value2 (torque), control word, reference1 (speed) and reference value2 (torque):
- communication profile in drive parameters: ABB Drives classic
- communication Function Block in AC500 program: Use ACS_COM_MOD_TCP ACS_COM_MOD_TCP Communication for ACS / DCS Drives via MODBUS TCP, if PLC firmware is less than V2.4, else use ACS_COM_MOD_TCPx ACS_COM_MOD_TCPx Communication for ACS / DCS Drives via MODBUS TCP
- control Function Block in AC500 program: ACS_DRIVES_CTRL_STANDARD ACS_DRIVES_CTRL_STANDARD Control of ACS Drives with ABB-Drives Profile
- scaling: ACS_REF_SCALING ACS_REF_SCALING Scaling for ACS / DCS Reference and Actual Values(optional)
- status word, actual value1 (speed), actual value2 (torque), control word, reference1 (speed), reference value2 (torque) and up to 10 more values read from drive and up to 10 more values write to the drive
- communication profile in drive parameters: ABB Drives enhanced
- communication Function Block in AC500 program: Use ACS_COM_MOD_TCP_ENHANCED ACS_COM_MOD_TCP_ENHANCED Communication for ACS / DCS Drives via MODBUS TCP, if PLC firmware is less than V2.4, else use ACS_COM_MOD_TCPx_ENHANCED ACS_COM_MOD_TCPx_ENHANCED Communication for ACS / DCS Drives via MODBUS TCP
- control Function Block in AC500 program: ACS_DRIVES_CTRL_STANDARD ACS_DRIVES_CTRL_STANDARD Control of ACS Drives with ABB-Drives Profile
- scaling: ACS_REF_SCALING (optional) ACS_REF_SCALING Scaling for ACS / DCS Reference and Actual Values
- to exchange more than above mentioned values use additionally the following blocks:
- ACS_MOD_READ_N_PRM ACS_MOD_READ_N_PRM Read N Parameters from an ACS Drive via MODBUS RTU
- ACS_MOD_WRITE_N_PRM ACS_MOD_WRITE_N_PRM Write N Parameters to an ACS/DCS Drive via MODBUS RTU
